I am having a strange case after renaming a domain controller.
I am in the process of replacing 3 of my win 2008 R2 DCS with 3 new Win 2012 R2 DCs.
Ive done 2 so far by renaming them to -OLD, then promoting a new DC with original name.
On my 3rd DC which is also the primary FSMO, I was able to rename it to SERVER1-OLD, I also transfered all 5 roles to SERVER2.
Now I am ready to rename SERVER1-NEW to original name SERVER1, but its giving me error computer already exists
Ive given it 2 hrs to replicate after renaming the DC, the AD record no longer exists, The DC is called SERVER1-OLD , the DNS record also doesnt exits. I did a search in AD for computer SERVER1 and it didnt find it.
I also checked ADSI Edit, and its all clean, no mention of the record.
My DC diag looks ok, except some SNMP error, and no errors show in event logs for AD for over 2 hrs now.
I used the same method on my 2 other DC with no issues. The only different is this one was primary DC.
I tried renaming it to SERVER1-NEW2, and it worked, so its not a issue with my new server or the renaming process, it just doesnt like the original name SERVER1
Ill give it 12 more hrs to replicate, I hope it works by then, it should now but it doesnt.
Ive created new objects in AD, and they replicate in 15min.
Help is appreciated.
