'C:\Windows\System32\AUTOEXEC.NT. The system file is not suitable for running MS-DOS and Microsoft Windows applications', as per the message below , or a similar such message mentioning either the command.com file or config.nt files:
then one of your system configuration files (normally autoexec.nt) is missing a configuration entry.
Please click on sysfiles.exe and choose 'open' at the prompt to update your autoexec.nt, config.sys and command.com files with the correct entries.
This is a known problem with Windows XP as detailed on the Microsoft web site.
