Autoexec.nt

[George Cuckow]

When I start "Windows XP SP2 home" the following message pops up on the
desktop.

16-bit Windows subsystem
C:\Windows\system32\autoexec.NT. the system file is not suitable for running
MS-DOS and Microsoft Windows
applications. choose "close" to terminate the application

I believe it started after trying to get an old programme to run - "Red
Ace".
I told it to run as Windows 95 but without success and I then deleted the
programme.
I would appreciate any help to stop this happening.

P. S. I originally sent this e-mail in late January but I have been abroad
and was unable to see the three replies which are no longer on the server.
I would like to thank the people who replied and hopefully they will respond
again because the problems still exists-- many thanks

Hi

The January thread is available at the Google newsgroup archive:

Anyway:

Your autoexec.nt problem is most likely caused by a worm or if you have
WinXP SP2 and AVAST (antivirus software) installed, it also can cause
this error.

To solve the problem:

Error message when you install or start an MS-DOS or 16-bit
Windows-based program
http://support.microsoft.com/default.aspx?scid=kb;en-us;324767

Alternatively:

You can put back the standard version of autoexec.nt/config.nt by
copying a backup copy held in %windir%\repair\ to %windir%\system32\
(%windir% is typically C:\Windows) instead of using the procedure in
the KB article above (see further down for instructions on how).


Could be caused a trojan or something similar, e.g.
TrojanDownloader.Win32.Dia.a, more about this here:

Also, AVAST (antivirus software) can be the cause if you
have WinXP SP2 installed:

If you want to copy the file from the repair folder, you can use
this procedure:

Open a command prompt, using e.g. Start/Run --> cmd.exe

In the command prompt, type in the following two commands exactly as
you see them in this post (you need to press enter for each command
to execute them):

cd /d %windir%
copy repair\autoexec.nt system32\*.*


Here is a "screen dump" from how it looks when I do it on my computer:

Thanks to everyone for taking the time and trouble in helping me to solve
this problem.
I eventually copied the autoexec.nt file from C:\Windows\repair to the
system32 folder and then made sure that the autoexec.nt file was read-only.
I would not have managed this without your help, once again thank you all
very much.
