  • NTVDM encountered a hard error

    by michael · about 15 years, 11 months ago

    Recently we implemented a Terminal Services setup on W2K3 Standard for around 100 users. The hardware side seems to be fine but after we started testing the application (a mixed 32 and 16 bit app) we suddenly started getting NTVDM errors.
    NTVDM encountered a hard error.
    This is the only error explanation it gives. Have searched all Microsoft and various sites, including Googling, and have tried all suggestions in both MS KB fixes (replace relevant files etc) and change TEMP & TMP environment variables to 8.3 maximum format to no avail. Has anyone come across this problem or have any suggestions how we can further troubleshoot/rectify the problem?
    Hardware is dual Xeon 3GHz with 4Gb RAM and 40Gb O/S drive with 140Gb data drive (both SCSI_320 mirror sets).
    O/S is WIN 2003 server with SP1 and all current patches. Clients are all WIN XP Pro SP2.

    Thanks people.

      Have you confirmed that this application is designed to run in a TS environment? Can you run it in a standard Windows environment? It sounds to me like the application is trying to do something “illegal” (read – not allowed by the Win2K3 kernel) on the 16-bit side, like possibly some sort of direct control of a hardware resource, which is then causing the NTVDM to error out. I would consult with the programmers or, if it’s a 3rd party app, with the company you purchased it from, to see if they can determine the cause.

      Hope this helps!

      In this case, the app. was running OK, but the developer/implementer decided that Remote Desktop Web Connection was required for some users to access it. Remote Desktop Web Connection (part of WWW Service/IIS) was added to the system, then SP1 was re-applied to the server.

      Since this, we are encountering the NTVDM hard error message whenever we try to do any 16bit work.

      I have checked the autoexec.nt and config.nt files, have re-expanded the command.com and ntvdm.exe files, have tested it from admin and user and we get this error all the time now, even trying to just run command.com. I have read all the posts I could find here and looked for this error in KB’s with no positive results. Have also reset the env var for TEMP and TMP to C:\TEMP to remove that possible failing.

      Are there any requirements to re-install the MS patches after re-installing a SP? Are there files that are replaced that could cause this behaviour if the security patches MS issues after a SP is released replace critical files? How can I safely re-run all the necessary patches if I need to do so?

      In reply to NTVDM encountered a hard error

      The matter has been resolved. The problem was caused by an entry in the registry at:

      HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\VirtualDeviceDrivers\VDD

      which had an incorrect value in it pointing to a non-existant dll removed when we uninstalled Symantec Corporate Anti-Virus. This somehow caused the NTVDM to fail without an error message highlighting the fact that the file could not be found when the system tried to run it for the VDD value.

      Thanks people.

Hi there

Every time i boot my PC i'm faced with a Dos window with an error message.

I just click ignore and the error message vanished but i feel its affecting the performance of my PC.

My PC which is connected to my works domain runs windows XP and is only about 6 months old!

The MS - DOS window opens and the error prompt displays the following error message

16 bit MS - DOS Subsystem
C:\windows\system32\scchk32.exe
The NTVDM CPU has encountered an illegal instruction
CS:06d7 IP: 23ae OP:ff ff ff ff od
choose close to terminate the program

can anyone shed any light as my PC seems to be running painfully slow right now.

thanks in advance

 NTVDMx64 by Leecher1337


 A verson of NTVDM for 64-bit Windows

NTVDMx64 makes it possible to run old DOS applications under 64-bit Windows 7 and Windows 10. (It is reported to work correctly with Windows Server 2008 R2, and perhaps also with more recent Windows Server versions.)

Recent versions of NTVDMx64 make it possible to run 16-bit Windows applications under 64-bit Windows, but you may prefer to use the much less obtrusive otvdm/winevdmfor this purpose.

Unlike emulator applications such as vDos and DOSBox, NTVDMx64 is fully integrated with Windows, with the same access to the Windows file system and ports that NTVDM has under 32-bit Windows. NTVDMx64 does not perform as quickly as DOSBox or vDos, but its integration is a unique and important advantage. For example, a DOS application running under NTVDMx64 can print directly to LPT1 if the computer has a parallel port; this is impossible under DOSBox (although possible with vDos through a configuration option).

NTVDMx64 is not my work! It is a patched version of Microsoft's original NTVDM, based on the leaked source code of Windows NT, and patched by a programmer who calls himself "Leecher1337." The leaked source code may not be distributed legally, so, in order to avoid legal problems, Leecher1337 publishes only patch files that contain modifications to the original code. These patch files may be downloaded from his GitHub page. With the proper development environment, the patched Windows NT code can be compiled to build a 64-bit version of NTVDM, which Leecher1337 has named NTVDMx64. Don't be clueless! Do not waste your valuable time sending me questions about NTVDMx64! I don't know the answer! Post your questions on Leecher1337's GitHub page! I really mean this!

Leecher1337 does not distribute compiled versions of his patched version, but I have obtained copies of the CCPU and HAXM versions (see the GitHub page for details of requirements and differences). Each has an installer. I did not build these copies; I obtained them from another source.

To install NTVDMx64, run INSTALL.BAT, and restart your system when prompted. If you want, you may uninstall it from the Control Panel or PC Settings. This installer is frequently updated to match the latest version of Leecher1337's code. (Updated 19 August 2022.)

Warning:If Microsoft asks me to take down this page for any reason at all, the page and all files linked from it will be deleted immediately. Microsoft has not made any such request during the years that this page has been posted.

All comments and questions about NTVDMx64 should be posted on Leecher1337's Github page. Don't be clueless! Do not waste your valuable time sending me e-mails asking for help installing and running NTVDMx64, because I will not know the answers. Open an issue at the GitHub page for this project. Also, do not waste your valuable time asking me to update the version posted here. I have no control over which version is available to me.

Secure Boot: With Windows versions below Windows 10, you must disable the "secure boot" feature on your computer (if it is enabled). With Windows 10 and above, it's preferable but not strictly necessary to disable "secure boot.". To disable secure boot, you will need to modify the BIOS settings of your machine; it is not a Windows setting. If you don't know how to accomplish this, search the web or consult the manual for your system board.

Windows Smart Screen may refuse to let the installer run; choose Run Anyway from the buttons that appear when you click on More Info (or some similar setting). Windows Defender may block a DLL in the program; find it in the Quarantine settings, click on its name, and choose Restore. Other anti-virus programs may similarly block the installation. Don't complain to me or to Leecher1337; complain to your anti-virus vendor. And don't waste your extremely valuable time asking me or Leecher1337 whether this software is unsafe. If you don't want to override these security features, don't use this software.

Cautions and warnings: NTVDMx64 uses non-standard methods of process propagation to inject loader code into 32-bit and 64-bit applications. I don't know exactly what this means, but I am reliably told that this may cause problems not yet recognized. You may want to experiment with a VMware or other virtual machine before running it on production systems. Also, it has been tested only under the 64-bit versions of Windows Server 2003, Windows 7, Windows 8, Windows Server 2008, Windows 10, and Windows 11. Do not attempt to run it under any earlier version!

You may launch DOS applications from the Windows command prompt (CMD) or by double-clicking them in Windows Explorer. The first time you try to run any DOS program, you may see an error message; try again immediately afterwards, and the program should run.

Some programs will require command-line switches to run. For example, WordPerfect for DOS 6.x should be started with the /NE command-line switch. Some programs will not run at all; there is probably nothing that can be done about those programs, but you should feel free to file a very detailed "issue" at the GitHub page linked above.

Microsoft's NTVDM uses a licensed version of the SoftPC emulation software by Insignia. The original NTVDM, written for Windows NT, operated differently when run on Intel's x86 hardware and on alternate hardware, including VAX VMS, DEC Alpha, and Mips. SoftPC included a software-based CPU (CCPU) that could emulate an Intel 80386 processor. For performance reasons, when running under an Intel processor, the emulated CPU was not used; instead, the V86 mode of the hardware CPU was used, via a kernel interface which Microsoft called "Monitor". So the CCPU was used only on non-x86 architectures, and the Monitor interface was used on x86. Leecher1337's NTVDMx64 modifies the original code so that the CCPU is used when running under 64-bit Windows, because Intel processors have no V86 support in the "long mode" used by 64-bit Windows.

NTVDMx64 makes one change in the CONFIG.NT file from the original NTVDM: it increases the FILES = line from 20 to 100, which should be sufficient for most applications). If you want to change that number, or make any other changes in CONFIG.NT, do the following: run CMD.EXE as an administrator; navigate if necessary to \WINDOWS\SYSTEM32 and run the command "start notepad config.nt", and edit the file.

For a full description, see Leecher1337's Github page, which also notes some problems with DPMI programs and DOS extenders.

Like NTVDM, NTVDMx64 can be customized from the system menu of an NTVDMx64 window to change window size, display font, etc. Unlike NTVDM, the CCPU version switches smoothly between text and graphic modes (the HAXM version reportedly will never work smoothly with graphic modes).

    Reasons For Ntvdm . Slow Exe Performance

    However, several errors accompany the performance of ntvdm.exe, which can cause the user to experience a system malfunction. Some of these errors are temporary and appear on their own unless additional effort is required to correct them. However, some errors persist longer and appear later and do not resolve themselves. This is an alarming case that needs to be addressed in order to fix it and avoid big problems. However, it is not only rare that ntvdm.exe is mostly infected by third party software, also known as virus infection. This is often discussed in detail below.

    Ntvdm.exe uses over 90% of the processing power of your processor. This usually happens when the user is trying to run certain MS-DOS applications, although there have been few such tasks lately. However, a DOS emulator is considered the most recent viable solution to this problem.

    Actual Problem - I am trying to install a JMF API(http://www.oracle.com/technetwork/java/javase/download-142937.html) to my laptop with JDK (Java SE Development Kit 7) already installed.
    When I try to run the installer, I am facing the "16 bit Windows Subsystem" error.

    Also, it is noticed that the the same error "16 bit Windows Subsystem" gets popped up on trying to run "command.com" in Start -> Run

    I tried the following troubleshooting tips. But, all in vein.
    1) I tried to repair the windows xp operating system using a CD - I had some hard disk sync problem.
    2) I tried to replace the NTVDM file from the location C:\WINDOWS\system32 - It could not be replaced.
    3) I downloaded a COMBOFIX for my XP machine and ran the same - It did not pop any errors

    Hello
    You are able to use your applications without problem?

    To check what is causing the problem, try the following steps:

    1:NTVDM method is bound to display drivers for nVidia.I suggest you to update display drivers on the manufacturer's Web site

    http://Windows.Microsoft.com/en-us/Windows7/update-a-driver-for-hardware-that-isn ' t-work correctly

    Method 2: Clean boot

    Put the computer in a clean boot (namely if any third-party software hinders the process)
    How to troubleshoot a problem by performing a clean boot in Windows Vista or in Windows 7
    http://support.Microsoft.com/kb/929135

    Check with step 1 (run a clean boot):-If everything works well after a clean boot, you can deduce that some third-party services are at the origin of the problem.
    Continue with the remaining steps to pin-point on the third party service.

    Note: After you find the program causing the problem, you will have to perhaps to update or install a newer version of the program and also don't forget to put the computer to a normal startup.

  • How to disable the annoying NTVDM. EXE error message

    I spent an hour or two to try to determine what is causing the NTVDM. Error EXE that occurs during startup - all to nothing does not.

    Somehow I think that there is a setting that will turn off the annoying message - as it serves no useful purpose.

    Someone has any idea how to do this in Vista?

    Thank you

    -pr-

    It is easy to use Google Reader and share it here. What will be the exact wording of the error message?

    I used the AUTORUN application and found two remnents in a program file deleted which do not uninstall correctly. Error no longer appears on over the connection.

  • NTVDM. EXE error because Windows Update yesterday

    Since the last version of Windows XP update yesterday, two of my eight computers will not open my program back. I get a message: NTVDM. EXE has encountered a problem and needs to close. AppName ntvdm.exe. AppVer 5.1.2600.5512. ModName kernel32.dll. 5.1.2600.5781 ModVer; Offset 00012afb. This problem is not consistent on all my computers, but is still a big problem for me. Love some tips.

    I want to thank all of you for your time and your thoughts. This is what took place:

    (1) before I dive deeply on the question, I did an image of the hard drive in question. I took the original disc, step by step repair of Windows, and on the last restart, the system could not load anything on the desktop, or pull up the Windows Activation Wizard. I then proceeded in the service of Microsoft's response and intensified in grade over several sessions and many hours. This path has never produced fruit.

    (2) I took the other disk "image" and had two technicians to address them without success. I also did all of your suggestions.

    (3) Finally, I made a new image a month ago since my last Backup Exec from Symantec. I did a scan of the CFS and installed 17 updates one at a time. The KB2707511 was again the culprit, and it is removed and hidden. I found it interesting that KB2707511 was not part of my series of update of original disc, but it appeared on this reconstruction of the hard drive.

    Lessons learned:
    (1) never delete restore points.
    (2) not to do a Windows repair without corresponding to the level of the disc at the level of the windows installed - ala remove Service Pack 3
    (3) Although the software is a pain, stand the Symantec Backup Exec.
    (4) you tech guys are very generous and a great help.

    Thanks again,
    gfgman

  • NTVDM.exe is suspended.

    Windows XP Pro SP3.
    NTVDM.exe has suddenly stopped working if I run cmd.exe or command.com.  No error message, no prompt, just a blinking cursor.  If I run cmd.exe orders BACK internal DIR & CD work fine, but when I try to run one of my programs ntvdm.exe BACK starts and crashes.  When I run command.com ntvdm.exe starts immediately and crashes.

    It started when I installed a trial version of Nero 9 CD burner.  I discovered this problem and uninstalled Nero 9 about 2 hours later, but the problem persists.  The crew of Nero tech support had me do a scan and send it to them, but concluded that it did nothing to my computer to cause this problem.  I noticed that I have an empty folder named WindowsPowerShell in the windows\system32 directory, but I don't know if it's there before installing Nero 9.  I never used it.  I also noticed that there are no dosx.exe in the windows\system\32 directory.  I copied the \dllcache folder and that made no difference.  Seven weeks to research on the net has produced nothing.  I discovered yesterday the Process Monitor from Sysinternals and installed.  Exciting program!  After scanning through thousands of lines of events after ntvdm.exe begins until it crashes, several times, the only thing I found is an 'access denied' something done ntvdm.exe.  I don't remember the details.  None of the missing files.

     NTVDMx64 by Leecher1337


     A verson of NTVDM for 64-bit Windows

    NTVDMx64 makes it possible to run old DOS applications under 64-bit Windows 7 and Windows 10. (It is reported to work correctly with Windows Server 2008 R2, and perhaps also with more recent Windows Server versions.)

    Recent versions of NTVDMx64 make it possible to run 16-bit Windows applications under 64-bit Windows, but you may prefer to use the much less obtrusive otvdm/winevdmfor this purpose.

    Unlike emulator applications such as vDos and DOSBox, NTVDMx64 is fully integrated with Windows, with the same access to the Windows file system and ports that NTVDM has under 32-bit Windows. NTVDMx64 does not perform as quickly as DOSBox or vDos, but its integration is a unique and important advantage. For example, a DOS application running under NTVDMx64 can print directly to LPT1 if the computer has a parallel port; this is impossible under DOSBox (although possible with vDos through a configuration option).

    NTVDMx64 is not my work! It is a patched version of Microsoft's original NTVDM, based on the leaked source code of Windows NT, and patched by a programmer who calls himself "Leecher1337." The leaked source code may not be distributed legally, so, in order to avoid legal problems, Leecher1337 publishes only patch files that contain modifications to the original code. These patch files may be downloaded from his GitHub page, ntvdm hardware error. With the proper development environment, the patched Windows NT code can be compiled to build a 64-bit version of NTVDM, which Leecher1337 has named NTVDMx64. Don't be clueless! Do not waste your valuable time sending me questions about NTVDMx64! I don't know the answer! Post your questions on Leecher1337's GitHub page! I really mean this!

    Leecher1337 does not distribute compiled versions of his patched version, but I have obtained copies of the CCPU and HAXM versions (see the GitHub page for details of requirements and differences). Each has an installer. I did not build these copies; I obtained them from another source.

    To install NTVDMx64, run INSTALL.BAT, and restart your system when prompted. If you want, you may uninstall it from the Control Panel or PC Settings. This ini_set display_errors 1 php is frequently updated to match the latest version of Leecher1337's code. (Updated 19 August 2022.)

    All comments and questions about NTVDMx64 should be posted on Leecher1337's Github page. Don't be clueless! Do not waste your valuable time sending me e-mails asking for help installing and running NTVDMx64, because I will not know the answers. Open an issue at the GitHub page for this project. Also, do not waste your valuable time asking me to update the version posted here. I have no control over which version is available to me.

    Secure Boot: With Windows versions below Windows 10, you must disable the "secure boot" feature on your computer (if it is enabled). Ntvdm hardware error Windows 10 and above, it's preferable but not strictly necessary to disable "secure boot.". To disable secure boot, you will need to modify the BIOS settings of your machine; it is not a Windows setting. If you don't know how to accomplish this, search the web or consult the manual for your system board.

    Windows Smart Screen may refuse to let the installer run; choose Run Anyway from the buttons that appear when you click on More Info (or some similar setting). Windows Defender may block a DLL in the program; find it in the Quarantine settings, click on its name, and choose Restore. Other anti-virus programs may similarly block the installation. Don't complain to me or to Leecher1337; complain to your anti-virus vendor. And don't waste your extremely valuable time asking me or Leecher1337 whether this software is unsafe, ntvdm hardware error. If you don't want to override these security features, don't use this software.

    Cautions and warnings: NTVDMx64 uses non-standard methods of process propagation to inject loader code into 32-bit and 64-bit applications. I don't know exactly what this means, but I am reliably told that this may cause problems not yet recognized, ntvdm hardware error. You may want to experiment with a VMware or other virtual machine before running it on production systems. Also, it has been tested only under the 64-bit versions of Windows Server 2003, Windows 7, ntvdm hardware error, Windows 8, Windows Server 2008, Windows 10, and Windows 11. Do not attempt to run it under any earlier version!

    You may launch DOS applications from the Windows command prompt (CMD) or by double-clicking them in Windows Explorer. The first time you try to run any DOS program, ntvdm hardware error, you may see an error message; try again immediately afterwards, and the program should run.

    Some programs will require command-line switches to run. For example, WordPerfect for DOS 6.x should be started with the /NE command-line switch. Some programs will not run at all; there is probably nothing that can be done about those programs, but you should feel free to file a very detailed "issue" at the GitHub page linked above.

    Microsoft's NTVDM uses a licensed version of the SoftPC emulation software by Insignia. The original NTVDM, written for Windows NT, ntvdm hardware error, operated differently when run on Intel's x86 hardware and on alternate hardware, including VAX VMS, DEC Alpha, and Mips. SoftPC included a software-based CPU (CCPU) that could emulate an Intel 80386 processor, ntvdm hardware error. For performance reasons, when running under an Intel processor, the emulated CPU was not used; instead, the V86 mode of the hardware CPU was used, via a kernel interface which Microsoft called "Monitor". So the CCPU was used only on non-x86 architectures, and the Monitor interface was used on x86. Leecher1337's NTVDMx64 modifies the original code so that the CCPU is used when running under 64-bit Windows, because Intel processors have no V86 support in the "long mode" used by 64-bit Windows.

    NTVDMx64 makes one change in the CONFIG.NT file from the original NTVDM: it increases the FILES = line from 20 to 100, which should be sufficient for most applications). If you want to change that number, or make any other changes in CONFIG.NT, do the following: run CMD.EXE as an administrator; navigate if necessary to \WINDOWS\SYSTEM32 and run the command "start notepad config.nt", and edit the file.

    For a full description, see Leecher1337's Github page, which also notes some problems with DPMI programs and DOS extenders.

    Like NTVDM, NTVDMx64 can be customized from the system menu of an NTVDMx64 window to change window size, display font, etc. Unlike NTVDM, the CCPU version switches smoothly between text and graphic modes (the HAXM version reportedly will never work smoothly with graphic modes).

    (OP)

    Hi there

    Every time i boot my PC i'm faced with a Dos window cmd errorlevel exit an error message.

    I just click ignore and ntvdm hardware error error message vanished but i feel its affecting the performance of my PC.

    My PC which is connected to my works domain runs windows XP and is only about 6 months old!

    The MS - DOS window opens and the error prompt displays the following error message

    16 bit MS - DOS Subsystem
    C:\windows\system32\scchk32.exe
    The NTVDM CPU has encountered an illegal instruction
    CS:06d7 IP: 23ae OP:ff ff ff ff od
    choose close to terminate the program

    can anyone shed any light as my PC seems to be running painfully slow right now.

    thanks in advance

    • NTVDM encountered a hard error

      by michael · about 15 years, 11 months ago

      Recently we implemented a Terminal Services setup on W2K3 Standard for around 100 users. The hardware side seems to be fine but after we started testing the application (a mixed 32 and 16 bit app) we suddenly started getting NTVDM errors.
      NTVDM encountered a hard error.
      This is the only error explanation it gives, ntvdm hardware error. Have searched all Microsoft and various sites, including Googling, and have tried all suggestions in both MS KB fixes (replace relevant files etc) and change TEMP & TMP environment variables to 8.3 maximum format to no avail. Has anyone come across this problem or have any suggestions how we can further troubleshoot/rectify the problem?
      Hardware is dual Xeon 3GHz with 4Gb RAM and 40Gb O/S drive with 140Gb data drive (both SCSI_320 mirror sets).
      O/S is WIN 2003 server with SP1 and all current patches. Clients are all WIN XP Pro SP2, ntvdm hardware error.

      Thanks people.

      Michael

        Have you confirmed that this application is designed to run in a TS environment? Can you run it in a standard Windows environment? It sounds to me like the application is trying to do something “illegal” (read – not allowed by the Win2K3 kernel) on the 16-bit side, like possibly some sort of direct control of a hardware resource, which is then causing the NTVDM to error out. I would consult with the programmers or, if it’s a 3rd party app, with the company you purchased it from, to see ntvdm hardware error they can determine the cause.

        Hope this helps!

        In this case, the app. was running OK, but the developer/implementer decided that Remote Desktop Web Connection was required for some users to access it. Remote Desktop Web Connection (part of WWW Service/IIS) was added to the system, then SP1 was re-applied to the server.

        Since this, we are encountering the NTVDM hard error message whenever we try to do any 16bit work.

        I have checked the autoexec.nt and config.nt files, have re-expanded the command.com and ntvdm.exe files, have tested it from admin and user and we get this error all the time now, even trying to just run command.com. I have read all the posts I could find here and looked for this error in KB’s with no positive results. Have also reset the env var for TEMP and TMP to C:\TEMP to remove that possible failing.

        Are there any requirements to re-install the MS patches after re-installing a SP? Are there files that are replaced that could cause this behaviour if the security patches MS issues after a SP is released replace critical files? How can I safely re-run all the necessary patches if I need to do so?

        The matter has been resolved. The problem was caused by an entry in the registry at:

        HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\VirtualDeviceDrivers\VDD

        which had an incorrect value in it pointing to ntvdm hardware error non-existant dll removed when we uninstalled Symantec Corporate Anti-Virus. This somehow caused the NTVDM to fail without an error message highlighting the fact that the file could not be found when the system tried to run it for the VDD ntvdm hardware error people.
