I am runnning Windows XP Pro, with SP2 recently installed. Before I installed SP2, I could run DOS-based programs OK. Tell the system to run the program, and it would pop up the Command Prompt and run it. After I installed SP2, when I try to run most DOS-based programs, I get an error message saying "C:\Windows\System32\AUTOEXEC.NT The system file is not suitable for running MS-DOS and Microsoft Windows applications." Some programs, it will still run, but not very many. All of the programs I am having a problem with ran fine before I installed SP2. What's going on here and what can I do to correct it?
