Vista - Vista Enterprise Drops from Windows AD Domain

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.

Hi gbmaryland,

Welcome to the forums.

After you add the Vista PC then reboot the Vista PC and it boots up to the login window, I think you have to click on "Switch User" button then tell it to log in to your domain. I had to do this to get my Vista PC's to log into our 2003 A.D. domain.

I actually get the logon prompt for typing in a UID / Password.

What happens, during the first boot after adding the machine to the domain, is that it asks for a UID / Password.

So you type in <domain>\UID & the password.

Then you get an error "the user ID or password are invalid."

Then, the Vista PC indicates that it is "shutting down" and reboots.

When it comes back up, it's not part of the domain.

If you are really fast you can logon as the local admin and the system will not reboot. BUT: It will remove itself from the domain.

This is making no sense at all!

This tells me that the user id/password your trying to use to add computers to the domain does not have the rights to do so. The user id and password has to be a Domain Administrator or in the Domain Administrators Group.

If the machine has a computer account in AD on a Windows 2003 domain controller, then it was properly joined to the domain.

The Vista PC is added to domain without issue.

...and the account is an Entreprise Admin (which includes the rights of Domain Admins).

Next idea?

Check to see if there is a policy set for login timeouts on the AD Server....
