rename autoexec.nt to autoexec.bak and try again.

There actually wasn't a autoexec.nt in system32, found it in repair folder mind you so i've copied it in and it now works (don't know how that happened anyways) ta

Here are the contents of mine anyway, may be default... (should be), may not be

REM The following line enables Sound Blaster 2.0 support on NTVDM.
REM The command for setting the BLASTER environment is as follows:

REM    where:
REM        A    specifies the sound blaster's base I/O port
REM        I    specifies the interrupt request line
REM        D    specifies the 8-bit DMA channel
REM        P    specifies the MPU-401 base I/O port
REM        T    specifies the type of sound blaster card

REM    left unspecified, the default value will be used. (NOTE, since all the

REM    match the real hardware setting.)  NTVDM supports Sound Blaster 2.0 only.
REM    The T switch must be set to 3, if specified.
SET BLASTER=A220 I5 D1 P330 T3

REM To disable the sound blaster 2.0 support on NTVDM, specify an invalid
REM SB base I/O port address.  For example:
REM    SET BLASTER=A0

As mentioned in another answer I made,the autoexec and / or config.nt files are sometimes accidently deleted in some SP2 upgrades, depending on your system... but as you found, the "repair" folder in Windows keeps copies.
This will throw up 16 or 32 bit application run error messages

I'm still on XP home from the box, haven't bothered upgrading (didn't like sp2 when i had it) and i've formatted since then. Hmm, not a clue what would have deleted it

Run AdAware and Spybot. Most likely your autoexec.nt file has been deleted by some malware program.
