Cmd/Command Errors

Z

Zilva Zanga

I'm running Winxp Pro sp2 inc all updates.
When I try to run 'cmd' from the start>run menu item I get this error
message immediately with gibberish printed in the dos box in the background:
C:\WINDOWS\system32\cmd.com
The NTVDM CPU has encountered an illegal instruction.
CS:054c IP:ffe4 OP:fe ff 1d 09 e9 Choose 'Close' to terminate the
application.

When I try to run 'command' from the start>run menu item I can exit to the
dos box which contains the expected text, but I get this error message when
I try to do anything:
C:\WINDOWS\system32\command.com
The NTVDM CPU has encountered an illegal instruction.
CS:065f IP:0102 OP:8f fc d1 e9 33 Choose 'close' to terminate the
application.

The only applications installed since it last worked were:
Limewire 4.9.28
Quicktime 6.5.2
ITunes 4.7.1.30
IPOD (application)
Uninstalling them did not affect anything.

I haven't installed any new hardware apart from connecting the IPOD as
required.

Can anyone interpret those error messages?

Hi,

Close all running programs. Locate ntvdm.exe in the \Windows\System32 folder
and delete it (it's probably corrupt). Reboot the system. See if the problem
goes away, as the file will be replaced by one from the system cache (System
File Protection at work).

The error message doesn't match but this is what worked for the last person
though that was with 2k...

Error: 16-bit app on XP SP2 :

There's a bit about trying the sfc /scannow prompt. No reply about it
working or not.

That didn't work. Winxp replaced it with another one. I tried deleting the
dll file as well which really upset winxp & I had to restore it.

Hi,

Didn't say anything about deleting the .dll file, just the executable. Do
the same thing with wowexec.exe - if it doesn't help, then follow Galen's
suggestion to run sfc /scannow.

You most likely have a virus. Try tying regedit in Start | Run and see what
happens.

cmd.com is probably a virus or virus related. There is no such file as
cmd.com in XP. The correct files are cmd.exe and command.com.

Update your antivirus software and run a full system scan.

Read this, you probably have other messed up files.
http://www.trendmicro.com/vinfo/virusencyclo/default5.asp?VName=WORM_ALCAN.A&VSect=T

These get disabled...
CMD.EXE
NETSTAT.EXE
PING.EXE
REGEDIT.EXE
TASKKILL.EXE
TASKLIST.EXE
TRACERT.EXE

And replaced by these...
CMD.COM
NETSTAT.COM
PING.COM
REGEDIT.COM
TASKKILL.COM
TASKLIST.COM
TRACERT.COM

Nice one! You know - I didn't even notice that. In fact while doing my
search to confirm that it was the right fix I'd typed in cmd.exe...
Sheesh... That's it... No more posting before noon.

Hi Galen,

I have seen this cmd.com show up in posts before. ;-)

If cmd.com were added without disabling cmd.exe, typing just cmd would open
cmd.exe. Windows searches for a file by using default file name extensions
in the following order of precedence: .exe, .com, .bat, and .cmd.

Interesting note...

[[MS-DOS searches for a file by using default filename extensions in the
following order of precedence: .COM, .EXE and .BAT.]]
