Nevermind, I got it. My windows guru of a roommate told me to search microsoft.com for "16 bit MS-DOS error" or something like that and the article told me to pop my XP CD in and execute these console commands
Code:
expand cd-rom:\i386\config.nt_ drive_letter:\system_root\system32\config.nt
expand cd-rom:\i386\autoexec.nt_ drive_letter:\system_root\system32\autoexec.nt
expand cd-rom:\i386\command.co_ drive_letter:\system_root\system32\command.com
It worked, unfortunately I got an itchy trigger finger and uninstalled VS.NET 2k3, I'll have to throw that back on soon. Grrrr....
