SP2/ ms-dos programs won't run

[Bchessen]

After SP2 my old MS-DOS programs won't run and I get an
error: 16 Bit Window Subsystem C:\windows\system32
\autoexec.NT he system file is not suitale for running
MS-DOS and microsoft Window applications

Any way to get these programs running again? I thought
about partitioning my hard drive and having one part as
W98

Thanks

See this article:

There's also a trojan that's been wreaking havoc, deleting the
autoexec.nt file:

There is something around that seems to be adding to the autoexec.nt
file. There is a backup one in windows\repair. Take a look at the one
in use (in windows\system32) and compare. There should be

REM Install CD ROM extensions
lh %SystemRoot%\system32\mscdexnt.exe

REM Install network redirector (load before dosx.exe)
lh %SystemRoot%\system32\redir

REM Install DPMI support
lh %SystemRoot%\system32\dosx

and perhaps some SET or PATH lines. Please report anything that has
been added, then copy that backup from windows\repair into
windows\system32

Thanks Rock - this looks as if it may be the source of the trouble

Yes, it's great to finally see one possible cause. Someone, don't
remember if his name was Tim or Jim, figured it out and posted this
solution to this newsgroup.
