Running xp pro sp3
All of a sudden no shortcuts to DOS batch files work. If you run the batch file using cmd.exe, the screen seems to ignore you and flash back to the desktop. If you run the dos batch file as an EXE a 16 Bit Dos subsytem error is returned that states that NTDVM CPU has encountered an illegal instruction. However, if you run Command.Com you are able to run the batch file from the c:\ prompt and everything works fine [batch and program].
I changed the environmental variable COMSPEC to point to command.com rather than cmd.exe but that had no effect.
Autoexec.nt and Config.nt seem to be the same as on other computers on my network. I did copy doskey.exe and dosx.exe from a newer computer[renamed the older versions] to no avail.
Did a system restore - no effect.
Any pointers for an amateur like me?
