Using computer management I renamed a current 2008 dc to a previous 2003 DC after I just demoted it. I also used the IP address of the old demoted 2003 dc and made it the IP on the 2008 dc, (I gave the 2003 dc an unused different IP).
I manually deleted the 2008 previous computername from the dns records. Everyting seems fine BUT in AD sites and Services the 2008 DC has its previous name, I manually replicated a few times and no changes.
I researched further and realized I should have used netdom command to rename DCs. Anyway, using the netdom command and doing a dc query I see the name of the 2008 DC as its old name as well. On the 2008 DC in ADSI edit on the OU=Domain controllers properties the vaule for the msDS-AdditionalDnsHostName is the new name (old 2003 dc name) that I want it to be.
So, clearly some things are not being replicated/changed properly.
What should I do to make sure the 2008 DC has the name I want it to be?
