Does anyone knows why small business server 2003 can not start after "spyware doctor" installation? windows picture appears and freezes saying "one or more drivers are missing" (or something closed to that)

Have you looked through the support pages for Spyware Doctor to see if others have had this problem?
I would remove it by booting into Safe Mode and uninstalling it. This will tell you if Spyware Doctor is the culprit.
