Rename a DC
Does anyone know how to rename a DC and ADUC forest?
The boss has decided that naming the server and pc's after the Simpsons charactors is too childish (despite her recommending we ask the children what to name it).
As such I shall be renaming the server and ADUC forest but I am unsure how to do it safely without ruining the setup - and I would hate to have to reinstall everythig again!
Any help would be much appreiated.
Renaming a DC is relatively painless, you need to demote it first, rename it and then re-promote it, however if you only have one DC than you may be better of building another DC with the correct name, promote it to a DC, wait for everything to replicate and then demoting and removing the old one
I've just done all that moving over from 2003R2 to 2008R2 servers, I changed the names of the old 2003 servers so I could use the same names for the 2008 servers. The 2003 servers become olddc-1 etc till all was replicated and they were decommissioned.
Removing a DC from a domain with only one DC is frought with danger, as is trying to rename a DC with out demoting it. Last time I tried that trick I totally wrecked the DNS, and spent way to much time fixing it.
As for renaming your forest, I've never seen it done, and don't think its possible with building a new one. It may be do-able with some serious AD tools but I wouldn't like to try! If somebody knows how I'd like to know too!
I'll just tell her that without redoing everythig from scratch it can't be done....it's taken us 6 months to get everything how we want it.
Plus I could set up a proper staff gpo when I migrate the old admin and sims server over.
