I have a server whose AD account got crazy; log on would take hours and not all DCs showed the computer account. Now it only boots if disconnected from the network. I am trying to remove it from the domain but get aa timeout or if it is connected I get an error message "A remote procedure call is already in progress for this thread". I deleted the computer account from the domain.
I tried using "netdom remove computername /force" and deleting the machine account in the registry (HKLM/security/secrets/$machine.acc) but still the server remains in the domain.
Is there a documented method to remove a server (or workstation) from a domain that is no longer available?
Is this only happening on this one computer? Deleting the computer account from ADUC should work. What is running on this server (exchange? domain controller? dns?)
Edited to add:
I would try forcing replication between DCs. Open ADUC. Goto Sites/yourSite/NTDS Setting. Right-click on the connection in the details pane, and select Replicate Now.
It's a little confusing as to whether you said the computer still shows in ADUC. If forcing replication changes nothing, then I'm afraid you'll have to reimage this computer.
