I have a story to tell and a question to ask.
The story, I had a Domain controller (ro1) in a multisite-single domain network that crashed. This DC was the first one in the AD and it had the roles PDC emulator, RID master and infrastructure master. Unluckily, this server also have production data that a SQL server application was using. So when the server crashed i have to rebuild it with the exactly the same name to dont mess things up with the application, although i am sure that for AD the crashed ro1 and this new one are diffirent because they will have a different RID (am i right?)
I was able to transfer those roles to a brand new DC that built, now the problem and my question, AD still “thinks” that ro1 is a DC and i need to fix that. I was thinking on changing the name to ro1 and then delete manually any entry in the AD that refers to ro1, but the problem is that i cant rename ro1, how can i tell AD that ro1 is not anymore a DC?…
Note: somebody advice me to promote ro1 to DC but i also read that after moving those roles the original holder of them should not be put into the network ever (but is my new ro1 with different RID the original holder)
Thanks in advance
