Hello,
I checked and dsentry.exe is not a 16-bit program. I disabled it on reboot
and the following results are: windows file protection comes up and says:
Please wait while windows verifies that all protected windows files are
intact and in their original versions.......this has occured 5 reboots since
I ran SFC yesterday. Also the system configuration utility comes up and asks
me to return to normal startup which would include dsentry.exe. What should
I do next? And is a possible virus involved? I currently run Adware SE,
Norton antivirus corporate edition, spybot and msn beta. Thanks for your
patience!

SFC isn't going to work on this one. dsentry.exe is from Dell not.

First see if dsentry.exe is a 16-bit program.
Locate and Right-click dsentry.exe and then click Properties.
A 16-bit program does not have a Version tab in this dialog box.
Disable dsentry.exe from starting at boot.

[[dsentry.exe is a valid program but it is not required to run on startup.
This program is not required to start automatically as you can run it when
you need to. It is advised that you disable this program so that it does not
take up necessary resources. The following information is a brief
description of what is known about this file.]]

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
