The system was upgraded from Server 2000 to Server 2003 with no problems. Unfortunately, after installing SP1 the Windows 2003 screen would display and then the display would blank and the machine would restart. This cycle repeats continuously. I restored most of the C:\WINNT directory from backup, and the windows booted and unistalled the service pack. what do I do to upgrade to SP1 ?
