I've been going through a Windows Server 2003 domain and noticed under the Sites and Services console that the site has several machines listed under its "Server" node that no longer exist. Some weird policy/replication issues have been going on with this domain, and I'm thinking this might have something to do with it. Long story short, there are currently three servers acting as domain controllers. The primary controller and one of the secondary controllers seem to be replicating fine, but the other secondary controller doesn't replicate properly, so GPO application is not reliable. I don't see a need for three DC's, so I planned on demoting this uncooperative server and deleting the non-existent server entries under Sites and Services. The domain is a bit messy from prior to my inheritance of it.
I'd like to clean it up, and I'm assuming that since these servers no longer exist, that I can simply delete them from the Servers node. Is that accurate, and is there anything else I should be checking given this discovery? Thanks.
