Hello,
I also currently have the same error message as described in this post. I
attempted to rectify it by using the sfc.exe, however, did not experience the
same good results. The error message I receive is:
C:\WINDOWS\System32\DSentry.exe The NTVDM CPU has encountered an illegal
instruction. 'Close' to terminate the application. What I did was:
C:\WINDOWS\SYSTEM32>sfc.exe then
C:\WINDOWS\SYSTEM32>sf scannow then; the result was:
c:\windows\system32\ntvdmd.dll had a bad signature and was restored to its
original version
and
c:\windows\system32\charmap.exe has a bad signature. File was restored to
its original version
and
this one could not be restored: oembios.sig The problem is I still get the
same error message. Is there anything else I could do?
Thanks in advance ~

Hi John,.
As long as sfc.exe is in c:\windows\system32 you do not need to worry about
it. sfc.exe has to run from a command prompt or the Run box. Clicking on
sfc.exe does nothing. As you have already seen.
sfc /scannow checks the files in C:\WINDOWS\System32 if any are screwed up
it replaces the screwed up file with a copy from
C:\WINDOWS\System32\dllcache or the Windows installation source files.
Which in your case is probably the C:\I386 folder.
Do this.
Click Start | Click Run | Paste this in the Run box...
sfc /scannow
Then click OK.
It should take a while to run.
If SFC.EXE did anything it will be in the Event Viewer.
Open the Event Viewer...
Start | Run | Type: eventvwr | Click OK |
Click System | Look at any Windows File Protection
entries
SFC.EXE-2FD11AB0.pf on c:\windows\prefetch All this file is, is a file to
make sfc.exe run faster.

Some challange this!
My Dell supplied XP disk is not the full works. No sfc.exe on there. I
searched and found 3 likely files on c:
sfc on c:I386 [Windows 2000 System File Checker]
SFC.EXE-2FD11AB0.pf on c:\windows\prefetch
sfc on c:\windows\system32 [Windows 2000 System File Checker]
The first and third just bring up a DOS screen (I think) very, very
briefly. The second brings the usual NTVDM error.
So, what's next? Thanks for your persistence!

John,
I found this...
NTVDM CPU Has Encountered an Illegal Instruction
http://support.microsoft.com/default.aspx?scid=kb;en-us;Q245184
The article states...
[[SYMPTOMS
When you attempt to run a 16-bit program on a computer running Microsoft
Windows NT 4.0 Service Pack 3, the program may quit immediately, or you
may receive the following error message:
Hidden Console of WOW VDM
The NTVDM CPU has encountered an illegal instruction.
CS: 04c3 IP:3937 OP:c71c 9d 37 00
Choose Close to terminate the application.
CAUSE
This behavior can occur if you use an incorrect version of the
Command.com file.
RESOLUTION
To resolve this issue, replace the Command.com file]]
I did some searching on Google and another fellow had this problem.
[[When booting up my computer I get the following error message:
C:\WINDOWS\System32\rundll32.exe
The NTVDM CPU has encountered an illegal instruction.

His rundll32.exe file was corrupt.
Either your command.com or rundll32.exe or both are corrupt.
Run the System File Checker, sfc.exe. Sfc replaces bad files.
Load your XP CD in your CD drive.
Start | Run | Type or paste: sfc /scannow | Click OK
It should take a while to run.
If that doesn't work we can replace rundll32.exe and command.com another
way.

Hi Wes<snip>
you're certainly trying hard, and I really appreciate the help! But, no
luck so far. I've tried both progressivly ending tasks with the Task
Manager and deleting Start Up items with msconfig. But the problem
persists. Is there anything else to try, or should I reinstall XP?
Thanks
