Is this problem new?

Check config.sys or autoexec.bat for any lines trying to load older device drivers and REM them out. Actually you could probably get away with REM everything out. If this dosn't work you might have to tinker with DOS session settings.

When you click MS-DOS you actually launch a PIF file, some kind of a shortcut. Have you tried Start|Run|Command ? If that functions fine, probably the PIF file is corrupt. It should be located in C:\Windows\Start Menu\Programs. You can safely delete it and create another one, just like you create a shortcut. As soon as Windows recognises it is referring to a DOS application (it should point to C:\WINDOWS\COMMAND.COM or C:\COMMAND.COM) it creates a *.PIF file in stead of a *.LNK file.
By the way, the COMMAND.COM file this PIF is referring to has not been replaced or so? Is it the same version as the one your PC boots from?

Thanks Jim,

We had done updates via network and this had caused conflics between COMMAND.COM's.
