DC screwed up after migration! HELP
HELP! We've migrated 2 DCs over to 2008R2, the first went over no problem after following a books recommendations, the second seemd to go over fine, until we realised that we couldn't see the shares from a remote PC. Basically the book said to DCpromo, change names and IPs of old and new servers, this worked on the first server and had no reason to doubt the book. However we appear to have found out the hard way that you shouldn't rename a DC after DCPROMO. We cannot change the name back (netlogon won't start), I can't dcpromo it to demote it, it's basically a box stuck off the network with a load of stuff on it. In the AD Sites and services the default-first-name-site list shows the DC withi it's old name. It's basically screwed at present, has anyone any ideas about how to recover from this?
