  • Article
  • 5 minutes to read

This article describes the symptoms, cause, and resolution steps for cases when Active Directory replication fails with error 1256: The remote system is not available.

Applies to:   Windows Server 2012 R2
Original KB number:   2200187

Symptoms

  1. The DCDIAG reports that the Active Directory Replications test has failed with error 1256: The remote system is not available.

    Starting test: Replications
    [Replications Check, <Destination DC>] A recent replication attempt failed:
    From <source DC> to <destination DC>
    Naming Context: <directory partition DN path>
    The replication generated an error (1256):

    The failure occurred at <date> <time>
    The last success occurred at <date> <time>

  2. REPADMIN.EXE reports that a replication attempt has failed with status 1256. REPADMIN commands that commonly cite the 1256 status include but are not limited to:

      Sample output from depicting inbound replication from LonEMEADC to LonContosoDC failing with The remote system is not available error is shown below:

    • NTDS KCC, NTDS Replication, or ActiveDirectory_DomainService events with the 1256 status are logged in the directory service event log.

      Event SourceEvent IDEvent String
      NTDS Replication ActiveDirectory_DomainService1085 *Internal event: Active Directory Domain Services could not synchronize the following directory partition with the directory service at the following network address.
      NTDS KCC ActiveDirectory_DomainService1308The Knowledge Consistency Checker (KCC) has detected that successive attempts to replicate with the following domain controller has consistently failed. The Knowledge Consistency Checker (KCC) has detected that successive attempts to replicate with the following directory service has consistently failed.

      Note

      Event 1085 is only logged if the NTDS Diagnostics value 5 Replication Events has been set to a value of 1 or higher.

    Cause

    Replication status 1256 is logged for the following reason:

    When the destination DC fails to bind to the source DC using RPC a win32 error code in the Repsfrom status for that partition - usually Schema or Configuration since these partitions are replicated at a higher priority. After an RPC bind failure has occurred, a cleanup routine will run to clear the destination DCs queue from that same source DC. This is done to avoid wasting time attempting to replicate with a DC that it can't connect to. Since it hasn't attempted a sync for the partitions that have been cleared from the queue, a status 1256 is logged. In a scenario where destination DC replicates Schema, Configuration, and several GC non-writable partitions from the source DC, the win32 error status for the Schema and Configuration partitions that caused the RPC bind failure is logged. The destination DC will then cancel the pending replication tasks for the remaining partitions and log win32 error 1256 for the status.

    In summary: 1256 is logged as the replication status per partition as a result of the destination DC cancelling the sync request from the source DC due to a connectivity failure previously encountered.

    Resolution

    The win32 error 1256 should not be the focus of troubleshooting efforts, instead find the replication status that led to the RPC bind failure and then follow the corresponding Troubleshooting Active Directory operations that fail with error... article.

    Diagnose Active Directory replication failures.

    In order to determine the actual win32 error to troubleshoot, use one of the following methods:

    1. View or output on the destination DC

      1. Identify Source DC in the output and list all win32 status messages per partition
      2. The win32 status that is listed that is not a 1256 should be the focus of troubleshooting efforts
    2. Use output:

      1. Filter column K, Last Failure Status: Deselect 0 and (Blanks)
      2. Filter column C, Destination DSA: Deselect (Select All) and select just the DC where the 1256 status is logged.
      3. If 1256 is logged on more than one Source DC, Filter column F, Source DSA: Deselect (Select All) and Select just one DC to narrow the focus.
      4. Column K, Last Failure Status will list the 1256's along with the real win32 error that led to the RPC bind failure.

      In the following example, win32 error 1722 is logged for the Configuration and Schema partitions and should be the focus of troubleshooting.

    When good Domain Controllers go bad!

    Scenario

    It’s a pleasant day and all is well with the world. Colleagues are skipping around the office with smiles on faces…until…duh duh daaa! One by one, services start failing:

    • Printers go offline:
      • First, for Win7 users
      • Then for all clients
      • Can still print from server though
    • File shares go offline
    • Active Directory replication fails
    • DNS console will not open

    Basically, your main Domain Controller (DC) has just taken a dump…and so have you!

    These are the steps I took to troubleshoot the issues and get everything back online.

    Solution

    Gather Information

    Run the following commands to gather useful information:

    ipconfig /all > c:\ipconfig.txt (from each DC/DNS Server) dcdiag /v /c /d /e /s: > c:\dcdiag.txt dcdiag /test:dns /s: /DnsBasic > c:\dcdiag-dnsbasic.txt repadmin /showrepl dc* /verbose /all /intersite > c:\showrepl.txt (dc* is a placeholder for the starting name of the DCs if they all begin the same - if more then one DC exists) repadmin /replsum > c:\replsum.txt

    Pour through the txt files and note down the errors. Some of mine included:

    • repadmin /showrepl
      • Last error: 1256 (0x4e8): The remote system is not available.
      • Last error: 5 (0x5): Access is denied.
      • WARNING: KCC could not add this REPLICA LINK due to error.
      • result 1722 (0x6ba): The RPC server is unavailable.
    • repadmin /replsum
      • (1722) The RPC server is unavailable.
      • (5) Access is denied.
    • dcdiag /test:dns /s: /DnsBasic
      • The host
      • Got error while checking LDAP and RPC connectivity. Please check your firewall settings.
      • Error: No LDAP connectivity.
      • invalid DNS server:
      • No host records (A or AAAA) were found for this DC.
      • Warning: no DNS RPC connectivity (error or non Microsoft DNS server is running).
      • Name resolution is not functional.
    • dcdiag /v /c /d /e /s:
      • EventID: 0x40000004 – The Kerberos client received a KRB_AP_ERR_MODIFIED error from the server.
      • EventID: 0xC00004B2 – The DFS Replication service failed to contact domain controller  to access configuration information.
      • EventID: 0xC000138A – The DFS Replication service encountered an error communicating with partnerfor replication group Domain System Volume.
      • The replication generated an error (-2146893022): The target principal name is incorrect.
      • Error: Detected circular loop trying to locate the ISTG.
    • repadmin /syncall
      • -2146893022 (0x80090322): The target principal name is incorrect.
      • SyncAll exited with fatal Win32 error: 8440 (0x20f8): The naming context specified for this replication operation is invalid.

    Some information seemed to conflict as similar tests for certain services failed (like DNS) yet you could still ping by name and confirm using nslookup. Moving on.

    Go through the errors one by one and search online for solutions. Here are some of the URLs I used to troubleshoot errors:

    By now things might seem to snowball, but stay calm and keep trying recommended steps from Microsoft, recording your steps along the way:

    1. At a command prompt, type the following command and press ENTER:
    2. net stop KDC
    3. If the KDC cannot stop, set its startup state to disable and restart.

    To purge the ticket cache

    1. At a command prompt, type the following command and press ENTER:
    2. klist purge
    3. Answer Yes for each ticket

    To reset the computer account password on the PDC emulator

    1. At a command prompt, type the following command and press ENTER:

    nltest /dsgetdc: /gc gave this error:

    nltest /server: /sc_query: gave this error:
    I_NetLogonControl failed: Status = 1355 0x54b ERROR_NO_SUCH_DOMAIN

    Know when to quit

    My troubleshooting ran on to a second day. By now, users were using a workaround to access printers and file shares, but the DC errors continued. At this point, I decided to demote the DC and just leave it as a file and print server; which is best practice anyway.

    After taking a snapshot of the DC (via VMware vCenter), I proceeded to go through the standard steps to demote a DC:

    1. Transfer all FSMO roles to another DC – this failed with a generic error (http://social.technet.microsoft.com/Forums/en/winserverDS/thread/3f49ddbc-c948-43ac-af21-2f5a4f3dce9b).
    2. Run dcpromo to demote DC – this also failed.

    Great. Now the only option was a forceful removal of the DC (http://technet.microsoft.com/en-us/library/cc731871(v=ws.10).aspx). I

    dcpromo /forceremoval worked fine. I then removed the DC from Sites and Services, at which point the FSMO roles were transferred to another DC, so I didn’t need to seize them. You used to have to go through a Metadata Cleanup, after forcing a demotion, but now this is done for you when you remove the DC from Sites and Services. This can be confirmed by following the steps here: http://www.petri.co.il/delete_failed_dcs_from_ad.htm

    Although this is much easier using 2008 R2, you will still need to tidy up a little in other areas:

    1. Remove all entries of failed DC in Name Server Tabs on all relevant DNS zone properties.
    2. Backup and restore DHCP database to another server.
    3. Tombstone WINs entries from failed DC:
      1. From another DC, go to WINS >Active Registrations > right-click > Delete Owner.
      2. Select failed DC.
      3. Replicate deletion to other servers (tombstone).
      4. The new DC will then take ownership of the records.
    4. Uninstall above roles from failed DC.
    5. Update DHCP and devices with static IPs to use the new DC’s IP Address for DNS and WINS. You did spin up a new DC right?!?!

    Another great tip I found was from this thread on Spiceworks:

    If we really want to be safe then open a command prompt with elevated privileges and run the following command
    csvde –f C:\\ad_details.csv
    This exports all contents of ASDIEdit to an excel file in the root of C drive called “ad_details.csv” Open this in Excel and do a find all for . If it finds any references then we have lingering objects and will need to perform a Metadata Cleanup.

    Conclusion

    Although this was a nightmare to troubleshoot – and I have a chip on my shoulder as I didn’t find the root-cause or fix the DC – I have more confidence in the steps to force the removal of a screwed up DC. Next time I’ll learn to let go a little faster.

    Update: I’ve just found more notes on this that may be useful in future:

    My DCDIAG reports that the Active Directory Replications test has failed with error 1256 "The remote system is not bus error 10 free color. Any body who can suggers?

    When the destination DC fails to bind to the source DC using RPC a win32 error code in the Repsfrom status for that partition - usually Schema or Configuration since these partitions are replicated at a higher priority.After an RPC bind failure has occurred, a cleanup routine will run to clear the destination DCs queue from that same source DC.This is done to avoid wasting time attempting to replicate with a DC that it can't connect to.Since it hasn't attempted a sync for the partitions that have been cleared from the queue, a status 1256 is logged.In a scenario where destination DC replicates Schema, Configuration, and several GC non-writable partitions from the source DC, the win32 error status for the Schema and Configuration partitions that caused the RPC bind failure is logged.The destination DC will then cancel the pending replication tasks for the remaining partitions and log win32 error 1256 for the status.

    Error 1722 RPC Server Unavailable (RPC_S_SERVER_UNAVAILABLE) is a quite common Windows error. Often domain administrators face this error when AD replication is not working as expected. However, the replication generated an error 1256, this error can also appear on workstations running Windows 10 or Windows Server, without the ADDS role installed. This article will show how to troubleshoot and fix the RPC error 1722 in different cases.

    Active Directory Domain Controller Replication Error: The RPC Server is Unavailable

    In this section we’ll take a look at the basic ways the replication generated an error 1256 fix Active Directory replication Error 1722: The RPC server is unavailable when syncing changes between domain controllers. You can face the error both in the domain controller event logs and when trying to start or check the replication status using the repadmin tool.

    For example, you want to check the current status of Active Directory domain controllers with the command:

    repadmin /replsummary

    error 1722 the rpc server is unavailable

    Or:

    repadmin /showrepl

    As you can see, some domain controllers return an error “(1722) The RPC server is unavailable”. This means that some domain controllers are unable to replicate AD data (or just inactive) for a few days.

    Hint. There is a similar error RPC Server is Unavailable 0x800706BA, which is usually not associated with Active Directory failed creating direct3d device error controllers, and can occur on any Windows device. This needs to be fixed differently.

    Let’s consider the typical reasons for such an error:

    1. The domain controller is offline (or broken);
    2. Changes have been made to the network, or new Windows Defender Firewall rules have been added to block the AD replication traffic;
    3. Incorrect DNS configuration on domain controllers, or invalid DNS records;
    4. Poor network performance or high latency.

    Make sure the specified domain controllers are powered on and the following Windows services are running on them:

    • COM+ Event System;
    • Remote Procedure Call (RPC);
    • Active Directory Domain Services;
    • DNS Client;
    • DFS Replication;
    • Intersite Messaging;
    • Kerberos Key Distribution Center;
    • Security Accounts Manager;
    • Server;
    • Workstation;
    • Windows Time;
    • NETLOGON.

    Note. Now let’s say a few socket error connect mysql about how replication works in an Active Directory domain. Replication (Synchronization) Active Directory is a fully automated process. Each domain controller periodically writes changes that occurred on other domain controllers (replication partners) to its local AD database (ntds.dit file). This means that to make changes from dc02 to dc01, it is required that dc02 should be the replication partner of the dc01.

    First of all, to verify that everything is fine with replication, the replication generated an error 1256, you need to make sure the UNC path \\lon-dc01 (this is a problematic DC that returns error 1722 RPC server unavailable) is accessible, and the SYSVOL and NETLOGON folders are shared.

    1722 the rpc server is unavailable

    If they are not available, use the built-in ping and tracert tools to test basic network connectivity between the RPC client and server:

    ping lon-dc01 

    tracert lon-dc01 

    If the RPC client and server are on different networks, make sure traffic is properly routed between them. If they are in different physical locations, check if the link between them is up.

    Then check the permissions on the NETLOGON and SYSVOL folders, and check the availability of TCP 135/445 ports, maybe they are blocked by the firewall.

    Now check if TCP port 135 (RPC locator) on the domain controller returning error 1722 is in the listening state. You can do this using telnet or the PowerShell Test-NetConnection cmdlet:

    telnet lon-dc01 135

    Or:

    Test-NetConnection lon-dc01 –port 135

    A common source of such problems is the incorrect DNS configuration on the DC. Check if the correct DNS servers’ IP addresses are specified in the DC network connection settings. The primary address should be the address of another DC, and the secondary one is its own IP address.

    the rpc server is unavailable domain controller

    Check the DNS health on a problem DC with the dcdiag tool:

    DCDIAG /TEST:DNS /V /S:<ProblemDCName>

    Active Directory uses the dynamic range of TCP ports for replication. Windows Server 2008 R2 (and higher) uses the following port the replication generated an error 1256 for TCP Dynamic RPC — from 49152 to 65535.

    In some cases, an AD administrator can bind (restrict) Active Directory replication traffic on a specific port. In this case, the fixed RPC port number must be configured in the domain controller registry. For example, to bind the AD replication traffic on TCP port 5000 (0x1388), you need to change the registry key on the domain controller:

    [HKLM\SYSTEM\CurrentControlSet\Services\NTDS\Parameters]

    "TCP/IP Port"=dword:00001388

    If firewalls are used on your corporate network and the replication port AD is fixed, then replication won’t work on the newly promoted DC. This happens because the DC will try to replicate with the partner over a random port from the dynamic RPC range that is blocked by the firewalls.

    After you’ve fixed all problems, the replication generated an error 1256, you can run the repadmin /replsummary command again, and check if the replication was successful. We also recommend initiating the AD replication manually and checking for errors. Make sure the dcdiag /a /q command doesn’t return errors.

    RPC Server is Unavailable (Error Code: 1722) on Windows 10/Windows Server

    On Windows, you may receive the error “1722 The RPC server is unavailable” if the local service/app on your computer cannot communicate with the service on the remote computer.

    Note. RPC is a widely used network communication protocol for exchanging data between local computers (RPC client) and remote computers (RPC server). If the RPC client is unable to connect to the RPC server, the “RPC Server Unavailable” error appears.

    In this case, first of all, you need to check if the services required for the RPC protocol are running on the remote computer:

    • Remote Procedure Call (RPC);
    • RPC Endpoint Mapper;
    • DCOM Server Process Launcher;
    • Remote Procedure Call (RPC) Locator service (is not typically running).

    Open the Service management console (services.msc), and check if the specified services are in the Running state. If not, start them manually.

    1722 rpc server is unavailable

    Also, some network applications may return error 1722 The RPC server is unavailable if TCP/IPv6 protocol is disabled on the computer.

    Open the replication generated an error 1256 properties of your network adapter in the control panel (Win + R > ncpa.cpl), and check if Internet Protocol Version 6 (TCP/IPv6) and File and Printer Sharing for Microsoft Network are enabled.

    (1722) the rpc server is unavailable.

    Then clear the DNS cache with the command:

    ipconfig /flushdns

    Some RPC-based services don’t work correctly when IPv6 is disabled. Try to enable the IPv6 protocol in the properties of the network adapter. If the “RPC server is unavailable” error persists, try to disable the Teredo protocol through the registry, the replication generated an error 1256. To do this, create a DWORD parameter with the name DisabledComponents and value 8 under the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters. Restart your computer and check RPC connectivity

    Also, RPC error 1722 can occur when you try to print a document on a remote computer with a shared network printer. In this case, you need to check if the remote computer is turned on, and the Print Spooler service is running on it. Open the services.msc console and start the Print Spooler service.

    Troubleshooting RPC Connectivity Using Portquery

    The Remote Procedure Call (RPC) protocol is used in Windows to communicate between computers over a network. Many built-in Windows services use RPC (Distributed File System, AD Replication, DCOM services, MSSQL, Exchange, SCOM, SCCM, NLB, Microsoft Cluster Services, Certificate services, domain join, etc.).

    The RPC protocol is based on a client-server model. The RPC server accepts and processes connections using the RpcSs service. Windows dynamic ports are used to communicate between clients and the RCP server (TCP Range from 49152 and up to 65535).

    The static TCP port 135 is used as the starting point for RPC communication. This port is listened by the RPC Endpoint Mapper (RpcEptMapper) service. In a normal RPC session, the client connects to the RPC endpoint mapper service on the server on port 135 and requests the dynamic port number assigned to the particular service. RpcEptMapper responds with the IP address and service port number (a random dynamic port is assigned when the service starts).

    The most common causes of RPC errors are:

    • Disabled RPC service;
    • Name resolution errors (DNS or NetBIOS);
    • Network connectivity issues;
    • RPC Traffic blocking by firewall.

    You can use the portquery tools to diagnose the availability of the RPC and RPC Port Mapper services (PortQry Command Line Port Scanner).

    To check the availability of the RPC Port Mapper port on a remote server, run the command:

    portqry -n <problem_server> -e 135

    windows was unable to open service control manager database error 1722

    In this example, you can see that the RPC Port Mapper service is available on TCP port 135. The service also returned a list of running RPC endpoints and the ports assigned to them (in square brackets). Check if the service you are troubleshooting is on this list. Check if the port assigned to your TCP service is not blocked by firewalls between the client and server.

    portqry the replication generated an error 1256 <problem_server> -p tcp -e 49666

    When good Domain Controllers go bad!

    Scenario

    It’s a pleasant day and all is well with the world. Colleagues are skipping around the office with smiles data protector scsi error faces…until…duh duh daaa! One by one, services start failing:

    • Printers go offline:
      • First, for Win7 users
      • Then for all clients
      • Can still print from server though
    • File shares go offline
    • Active Directory replication fails
    • DNS console will not open

    Basically, your main Domain Controller (DC) has just taken a dump…and so have you!

    These are the steps I took to troubleshoot the issues and get everything back sock error error = 10058 Information

    Run the following commands to gather useful information:

    ipconfig /all > c:\ipconfig.txt (from each DC/DNS Server) dcdiag /v /c /d /e /s: > c:\dcdiag.txt dcdiag /test:dns /s: /DnsBasic > c:\dcdiag-dnsbasic.txt repadmin /showrepl dc* /verbose /all /intersite > c:\showrepl.txt (dc* is a placeholder for the starting name of the DCs if they all begin the same - if more then one DC exists) repadmin /replsum > c:\replsum.txt

    Pour through the txt files and note down the errors. Some of mine included:

    • repadmin /showrepl
      • Last error: 1256 (0x4e8): The remote system is not available.
      • Last error: 5 (0x5): Access is denied.

      • Warning: no DNS RPC connectivity (error or non Microsoft DNS server is running).

      • SyncAll exited with fatal Win32 error: 8440 (0x20f8): The naming context specified for this replication operation is invalid.

    Some information seemed to conflict as similar tests for certain services failed (like DNS) yet you could still the replication generated an error 1256 by name and confirm using nslookup. Moving on.

    Go through the errors one by one and search online for solutions. Here are some of the URLs I used to troubleshoot errors:

    By now things might seem to snowball, but stay calm and keep trying recommended steps from Microsoft, recording your steps along the way:

    To stop the KDC

    1. At a command prompt, type the following command and press ENTER:
    2. net stop KDC
    3. If the KDC cannot stop, set its startup state to disable and restart.

    To purge the ticket cache

    1. At a command prompt, type the following command and press ENTER:
    2. klist purge
    3. Answer Yes for each ticket

    To reset the computer account password on the PDC emulator

    1. At a command prompt, type the following command and press ENTER:
    2. netdom resetpwd /server:/userd:\administrator /passwordd:*

    Some other commands I used included:

    dcdiag /test:CheckSecurityError /s dcdiag /testdomain: nltest /logon_query nltest /dclist: nltest /domain_trusts nltest /DSQUERYDNS nltest /DSREGDNS nltest /sc_verify: nltest /dsgetdc: /force net config rdr dsquery * forestroot -scope subtree -filter "(serviceprincipalname=)" -attr * -s

    nltest /dsgetdc: /gc gave this error:
    Getting DC name failed: Status = 1355 0x54b ERROR_NO_SUCH_DOMAIN

    nltest /server: /sc_query: gave this error:
    I_NetLogonControl failed: Status = 1355 0x54b ERROR_NO_SUCH_DOMAIN

    Know when to quit

    My troubleshooting ran on to a second day. By now, users were using a workaround to access printers and file shares, but the DC errors continued. At this point, I decided to demote the DC and just leave it as a file and print server; which is best practice anyway.

    After taking a snapshot of the DC (via VMware vCenter), I proceeded to go through the standard steps to demote a DC:

    1. Transfer all FSMO roles to another DC – this failed with a generic error (http://social.technet.microsoft.com/Forums/en/winserverDS/thread/3f49ddbc-c948-43ac-af21-2f5a4f3dce9b).
    2. Run dcpromo to demote DC – this also failed.

    Great. Now the only option was a forceful removal of the DC (http://technet.microsoft.com/en-us/library/cc731871(v=ws.10).aspx). I

    dcpromo /forceremoval worked fine. I then removed the DC from Sites and Services, at which point the FSMO roles were transferred to another DC, so I didn’t need to seize them. You used to have to go through a Metadata Cleanup, after forcing a demotion, but now this is done for you when you remove the DC from Sites and Services. This can be confirmed by following the steps here: http://www.petri.co.il/delete_failed_dcs_from_ad.htm

    Although this is much easier using 2008 R2, you will still need to tidy up a little in other areas:

    1. Remove all entries of failed DC in Name Server Tabs the replication generated an error 1256 all relevant DNS zone properties.
    2. Backup and restore DHCP database to another server.
    3. Tombstone WINs entries from failed DC:
      1. From the replication generated an error 1256 DC, go to WINS >Active Registrations > right-click > Delete Owner.
      2. Select failed DC.
      3. Replicate deletion to other servers (tombstone).
      4. The new DC will then take ownership of the records.
    4. Uninstall above roles from failed DC.
    5. Update DHCP and devices with static IPs to use the new DC’s IP Address for DNS and WINS. You did spin up a new DC right?!?!

    Another great tip I found was from this thread on Spiceworks:

    If we really want to be safe then open a command prompt with elevated privileges and run the following command
    csvde –f C:\\ad_details.csv
    This exports all contents of ASDIEdit to an excel file in the root of C drive called “ad_details.csv” Open this in Excel and do a find all for . If it finds any references then hddguru seek error occurred have lingering objects and will need to perform a Metadata Cleanup.

    Conclusion

    Although this was a nightmare to troubleshoot – and I have a chip on my shoulder as I didn’t find the root-cause or fix the DC – I have more confidence in the steps to force the removal of a screwed up DC. Next time I’ll learn to let go a little faster.

    Update: I’ve just found more notes on this that may be useful in future:
