ControlUp KaaS SChannel Events


Various Schannel events in the System Log


There are three Schannel events that are most commonly seen. Those are , , and

Troubleshooting/Research Steps

Secure Channel, also known as Schannel, is a security support provider (SSP) that contains a set of security protocols that provide identity authentication and secure, private communication through encryption. Schannel is primarily used for Internet applications that require secure Hypertext Transfer Protocol (HTTP) communication.

These errors indicate a problem with the cipher suite chosen, or just the fact that the two sides (client and server) cannot agree on a cipher suite to use. The error message description will vary depending on the actual error involved.

Event IDs , can be caused by certificate/TLS communication issues (like lack of compatibility)

Event ID indicates an SSL fatal alert. The error itself is vague. This may be logged if you try to initiate an HTTP connection to an HTTPS server, or if the server is being probed or scanned for vulnerabilities.

Similar to other Windows Events problems, the ControlUp Incidents pane is an excellent place to start troubleshooting application errors such as this. Start by double-clicking on the ‘Windows Events’ row in order to get to the 2nd level.

Once there, we want to group and sort in order to group all events from Schannel, so we type ‘channel’ in the filter box in the upper right corner. Grouping by the Event ID can be useful if there are a lot of errors, so we check that box. We clicked the ‘Computer’ column header to sort the list and make it easier to find what we’re looking for.

Now that we have grouped just the events we are interested in. double-click on that line takes us to the 3rd level, which will give us a list of every event captured by the Incident Trigger that meets the grouping of the previous screen. You can read through the list here, or export the entire table into Excel using the button at the top in order to further analyze the data, find patterns, make reports, etc.

For these errors, Wireshark and Fiddler are going to be the best sources of more in-depth information to get to the root cause of the specific message.

If the issue cannot be solved, or the error is expected, there is always the option of turning off Schannel logging altogether by setting EventLogging=0 (dword), under HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\SecurityProviders\SCHANNEL. Hiding the log is not a good security practice, however, it is an option. See for more information.

  • Error Schannel

    I get this error Schannel over and over and over and over again. It is listed on the site to help with this. I have no idea what it is, but my computer hangs again and again. I don't know if that's the reason, but it seems to be that the most frequent event listed in the event viewer.

    I restored my computer to the image that I made after the initial installation in July and this is done only after return to restore 12/06/09 points.

    It doesn't seem to be a problem with operating system Windows, or well these various restorations it would set. Nothing else has changed. No new material added and external equipment, I have connected, I unplugged to dismiss them. Everything I connected is an external hard drive (which I need for my backups) and the keyboard and mouse.

    The computer goes to a blue screen, usually after something like the opening of Windows Explorer, or something like that. Sitting idle, it seems not to happen. Or at least not too often.

    What is error Schannel I found the display on different sites, but none that are conclusive or tell me what to do about EXCATLY.

    Make the same mistake.  Just installed Trial Version of Outlook and noticed the message.

    The error occurs when I allow Outlook set up email on its own accounts.  The first test is on an encrypted connection that fails and then succeeds to the possibility to use an unencrypted connection.  The error occurs during attempts encrypted and happens 3 times in a row.

    Just my Server POP3 uses a password, so it seems that attempts to use an encrypted protocol is involved.  But perhaps someone who understands more info on how it works will not know what kind of scenarios could generate such a mistake.

    Also I noticed that if I let Outlook set up accounts, she will succeed by using incorrect server name.  Mine are pop-server instead of just pop, but Outlook install it anyway.  But access to electronic mail does not generate the error, even using the wrong server name.

  • Cannot add composer in the Horizon 6 display Administrator console


    I built a test environment, composed of three ESXi hosts U2.  One of those is I run the following

    VCenter - W2KR2 under SQLR2 Express SP3

    View - W2KR2

    W2KR2 composer running SQL Express

    By using the web client I can connect to VCenter and manage environmental happily.  I am trying to install composer in this environment VSphere however I can't connect to the server of composer in the administration view existing console.  I tried to use a server standalone composer and composer also installed on VCenter.  Point of view seems to work fine as I can connect to virtual desktops using PCoIP.  Now, I would like to test the functionality of clone bound using the composer.

    I use the self-signed certificates for this test, so that can see the warning when I try to add the composer box.  I can accept the cert, but get an error every time - the text is not always the same:

    "Error trying to connect to View Composer".

    or "a connection problem occurred between the connection to the server, View Composer vCenter Server.  Verify that all services are running and the ports and URLs is correctly typed"

    I confirmed that port is listening on both servers (Windows Firewall is disabled).  The VMware View Composer service is running on both servers and running under a local account.   I have checked the SQL and newspapers of composer on the composer dedicated server and vCenter, but can not see specific errors when you try to connect.  I checked the DSN and the database according to the installation guide and you can check the connection.

    What I see are the errors of SChannel VCenter and composer that correspond with connection attempts:

    SCHANNEL error # the following fatal alert has been received: 46

    I presume that these are related to the acceptance of the untrusted SSL certificate and therefore are the expected behavior.

    I have attached below newspapers and some screenshots of errors.

    Thank you

    Basic error on my part - trying to install composer in a display environment 6.  Once I ran the installer composer 6, everything was ok.

  • Erorr Schannel event ID

    Just recently, my server Windows R2 STD started to run slow applications. This event is one of many that appear constantly. Did some research online and it does seem that pop up with client systems. How it would turn out upwards on a R2 STD Server?

    Did some more research and it doesn't seem to be a consistency on what is the nature of the problem. Anyone know how I can understand what exactly is the cause of this problem?

  • Fix Schannel (KB) causes the saturation of the LSASS by MS SQL server service


    I manage a small NET web application that is running on Windows Server R2 under IIS, querying a server MS SQL Express using the MS SQL Native client.  Authentication is also on MS SQL and not windows.

    After applying the fix Schannel the performance of the application (see KB) has deteriorated to the point where it was more usable.  The reason proved that after application of the patch, MS SQL server deploys an excessive number of requests for authorization for LSASS (e.g. per second, while that the application requires only an application for authorization by the action of the user, because the necessary applications are all made under an authenticated connection).

    We also have ESET File Security , but disable the real-time protection did not make a difference - I don't expect that it is a factor.

    Someone has suggestions for what is possible in this situation so that we can correct the problem of Schannel and still have a working web app?  It's a question of having someone else?

    Thank you very much

  • Win2k3 Server IIS SChannel event "a fatal error occurred when creating the SSL server credential information."

    To make a long story short, I went to use client software that I use a few times a week and it would not connect to the server, complaining not found or number of SSL.  When research various dcom, schannel errors errors in the event logs and a few others, I systematically over the last 24 hours cleared up the boot is so now clean (no time starting network on startup and no message on the service could not start).  It seems that something has happened a month ago after that the server crashed where at least the first DCOM messaged presented themselves, but everything has been working well until it didn't.  The dcom patches end up having to do with the \rsa\machinekeys (and the way that it) had a few "account unknown" in it, I cleaned everything that (at a time since I removed all items in this folder, but then put their subsequent return (by crushing all except 2 after creating a new certificate), had to reinstall virtual server and iis 6) , at some point as well.  In any case, I'm at the point where everything works (no event log errors/etc) from startup until you try to connect to the IIS 6 Server using https at this point, you get the event SChannel "a fatal error occurred when creating the SSL server credential information." (no additional information) is connected and the client browser cannot access the site (you can keep trying and it does not work but no event log entry more).  So that's where I'm sitting, http: works fine, https: No.  Certificate appears in the default Web site correct, said valid and possesses the private key, port is there, all addresses by default, netstat shows port same process id as the port   I can't find a copy of SSLDiag do test to see if that prove something?

    So I need help what is not going to get this new job of fixing.  What should I do?

    "The following fatal alert was generated: The internal error state is ", source is Schannel, Event ID is , however I know this error is basically just saying the TLS handshake failed which is what the previous error is saying too.

    I can make this error occur intentionally by using sslscan, for example if I run , I see a list of accepted ciphers followed by this error:

    Each time I run this I get two pairs of errors in the eventvwr, but I don't know why or which ciphers are at issue. It says the SSL certificate is weakly encrypted, which I can fix, although I don't know if that's related to the TLS errors or not.

    I've seen other similar questions whose response is usually "disable schannel logging in the registry to hide the error", but that's not a fix, so I'm reluctant to do that.


    When your event viewer is flooded by the Channel Event ID alerts.

    &#;         What is the Operating System installed on your computer?
    &#;         Have you made any recent changes on the computer?
    Note: SChannel means secure channel.
    sChannel uses TLS for security encryption. As long as the sites you visit do not use TLS.
    Follow the steps below:
    1.      Open Internet Explorer.
    2.      Click Tools.
    3.      Click Internet Options.
    4.      Click Advanced tab.
    5.      Scroll down the list under Security, uncheck all the Use TLS options.
    6.      Click OK.

    Now restart the computer and check if the issue still occurs.
    If the issue still persists, then I suggest that you optimize the internet explorer settings on the computer.
    Follow the steps in the link below:
    How to optimize Internet Explorer:
    If the above steps do not help you, then you may try resetting the internet explorer settings on the computer, you may download the Microsoft fix-it from the above link which automatically resets the browser settings to default settings on the computer.
    For the Bluescreen issue, we require the exact error code or error message to troubleshoot further with this issue. To get the exact error code or error message you may have to disable the automatic Feature.
    Follow these easy steps to disable the automatic restart feature for system failures.
    1.         Click Start.
    2.         Type System in Start Search.
    3.         Click on System under Control Panel.
    4.         In the task pane on the left, click the Advanced system settings link.
    5.         Locate the Startup and Recovery area and click on the Settings button.
    6.         In the Startup and Recovery window, locate and uncheck the check box next to Automatically restart.
    7.         Click OK in the Startup and Recovery window.
    8.         Click OK in the System Properties window.
    9.         You can now close the System window.
          From now on, when a problem causes a BSOD or another major error that halts the system, the PC will not automatically reboot. Rebooting manually will be necessary.
    Now when the blue screen occurs make a note of the error code or error message provide us the same.
