Ok,

I've got a production network that I'm test Windows Vista x64 Enterprise on.

I'm at my witts end with this problem:

I add the Vista PC to the Windows domain. The computer performs the tasks and then tells me it needs to reboot. Upon rebooting it immeadiately drops itself from Active Directory (Windows 2003 SP2 R2 based domain).

Oddly, the computer account in active directory is still there. The Vista client drops itself, but the server side thinks everything is fine.

What the heck is causing this?

There are no issues with IPv4 connectivity. (We don't use IPv6...)

The server shows that the PC and the users are connecting to the domain securely, and without issues (pass security audits).

The Vista Client (Enterprise x64) just drops itself from Active Directory.
