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.

Replace the standard version of autoexec.nt/config.nt by copying a backup copy
located in %windir%\repair\ to %windir%\system32\
(NB: %windir% is typically C:\Windows)

Also can be caused by a Trojan installing a file windupdater.exe and
creating registry entries for that file.

AVAST (free antivirus software) can be the cause if SP2 is installed:

Hi Mark,

Create a new autoexec.nt file and save it to the \windows\system32 folder.

Click start/run and type notepad, then click ok. Copy/paste the below code
into it (instead of typing it in to prevent errors), then click file/"save
as". Navigate to the C:\Windows\system32 folder, change the "save as file"
type to "all types" and name the file autoexec.nt, then click save (if
prompted to overwrite the existing one, do so).

@echo off
lh %SystemRoot%\system32\mscdexnt.exe
lh %SystemRoot%\system32\redir
lh %SystemRoot%\system32\dosx
SET BLASTER=A220 I5 D1 P330 T3

Reboot when finished. This usually fixes it, but you will find further steps
here if it doesn't:

Basically, you will have to expand new copies of command.com, autoexec.nt,
and config.nt to the system32 folder from the WinXP CD or I386 folder on
your hard drive, or copy them from the C:\Windows\repair folder to the
C:\Windows\system32 folder. Sometimes, you need to create new ones and
overwrite the existing ones - the method is described in the article.
