I have two domain controllers running win 2008 R2. I need to rename my primary domain controller from abc.xyz.com to 123.xyz.com.

Can I do it. Any problem in renaming the PDC. I am running DHCP and DNS in the PDC server.

Run the dcdiag /q repadmin /showrepl command and check all is working fine with out any error.

Please refer below aticle to rename your domain name:




The identity (domain GUID) of the renamed domain does not change during  a domain rename operation. Thus a computer's domain membership does not change as a result of the holding domain being renamed.

Should be pretty straight forward that you have two DC's
Follow the TechNet how to and you should be fine.
I would make sure that you have a backup of the DC systemstate.

Also not affect any DHCP and DNS in the PDC server.
