Now I've done it. I've killed my Primary Domain Controller. I had already installed the Windows 2000 Service Pack 1 on over 40 workstations, as well as the backup domain controller, then I decided to come in on a Saturday and do the primary server, named Jupiter. It installed fine, rebooted, then just sat at "Preparing network connections" for well over an hour and a half. I tried safe mode, which would let me login, but then it'd just sit there. I tried running the recovery utils on the CD, no luck. I tried the "last known good" menu option, still nothing. So now, I'm re-installing Windows on the system partition, and being thankful that I have a backup domain controller which has all my user information saved, so I don't have to re-create 50 accounts and passwords.

What did I do wrong? I didn't find any of the usual gripes about this service pack hosing a server on the web. I assumed this was a "safe" patch to install. In about half an hour, when my server finishes installing the OS, I'll try the patch again, just to see what happens this time. I already have to go through the trouble of re-creating about 25 different file shares, so I may as well try to update it again.
