i am running xp pro sp2 when i put a a program disk into my cd or dvd it says c:\windows\system32\autoexec.nt the file is not suitable for running ms dos then i get to pick close or ignore but nothing happens no matter what one i pick i know the disks are ok cause i formated the comp and it was fine at first but it came back a few days later

See if this helps:
