2008 Server Rename not Updating AD

Hi

I have renamed a 2008 servers physical name through 'Computer->Properties->ChangeSettings'. Now i would have expected that once I renamed the machine physically, AD will get this update automatically & it should display the new computer name.

While many of the attributes in the properties of this server in AD have updated correctly (computer name & DNS name) the display name didn't update.  I'm a domain admin and even gave myself full control security rights to the computer object, but it won't update.

This is the first time I have seen AD not update a display name after renaming a server...

Any ideas?

Thanks!

Tony

I assume you server 2008 is member of domain.
If you ping server 2008 from your DC like " ping -a server2008 " ( server2008 = your server name) , does it respond with your new server name or old server name ?

When you say name is not updated, are you referring to the name list in "Active directory user and computers" object list or in DNS server records ?

If it is updated correctly in "Active directory user and computer" object, try "ipconfig /flushdns" in cmd inside your Domain controllers (all DCs if you have more than one) and see the result.

DNS is updating fine, its just the display name when I do a search for computer names.  Yes, exactly, its the name list in "Active directory user and computers" that is not updating.


Pings with the correct server name.  Flushing DNS on the DC's didn't help...

Something wrong in your DC I guess.
When you say it is not renaming, is it showing as disconnected machine name in Active directory user and computer or showing as connected machine object ?

To confirm, you can do a search as mentioned here http://adriank.org/microsoft-active-directory-computer-name-contains-search-string/ and see whether it is in different OU?

If it simply not renaming for domain joined machine, you might have some issue with AD replication.
You can try to restart AD DS service from services.msc .

Anyway the quickest way you can to try to fix is.
- Unjoin machine from domain (make it as workgroup)
- delete old machine name object in Active directory user and computer.
- Join back to domain using the new name you were trying to set.
