I believe I have a rootkit. But, nothing will remove it. I've tried everything. Even tools that are merely for scanning fail or bsod the computer.

Since nothing works, I wanted to try and do it manually.

edit: This is a Windows 2000 Server Forest Root. I cannot rebuild it without blowing up the domain.

I'd strongly advise to rebuild your server.

if the server has been root-compromised how can you assure integrity of all of its parts even if you THINK you've removed the compromised part ?
it's easier and saves the time and hassle - rebuild and restore from backups
