I am a the System Administrator at a company that has 3 Windows Domain Controllers. Two of them are Windows 2003 and one is a WIndows 2008 R2. Running in 2003 level.
The Previous Domain name was Sixl's.com when the servers were running windows NT3.5 and 4.0. Now that they are running Windows 2003 and Active Directory, the old DOMAIN NAME seems to be hanging around. I checked the AD and there is only ONE DOMAIN and it is called sixls.com. All the users, etc are in that tree. But when you log into the network you use sixl's as the domain name. The sixls domain does not seem to be the login Domain. Yet all AD functions, security, policies, etc work fine.
So I seem to be missing some understanding about where this old Domani name is living and why it still seems to be the DOMAIN authority. The Old Name has an apostrophy in it and that is causing problems in some of our new endeavors. That is why they have a AD Domain of sixls.com now.
How can I get rid of the OLD Domain Name from the Domain Controllers so the new AD Domain sixls.com is all there is.
I checked SItes and DOmains and Trusts and there is only One top level Domain and that is sixls.com.
I assume that the OLD domain name was Migrated into the new DCs as upgrades through the years.
