Need to rename an AD Domain

Posted on 2012-09-08

About 8 years ago an AD domain was created in a Win2k3 environment called ''.  With the introduction of a Win2k8R2 domain controller there are potential DNS issues and the actual .net domain exists and is owned by someone else.  I need to change the name of the domain to 'mydomain.local'.  The infrastructure is very simple, 2 DC's, one 2008R2 and on 2003, a couple of other 2003 servers and about 80 workstations, with 200 users, it is a school.  No Exchange or SQL servers in the environment.  This is a single forest/domain infrastructure, quite simple.  Forest and domain functional levels are both Windows 2003.

My question is simple I hope.  Is it best to use the MS Rendom procedure or is there a better method?  I would hate to have to recreate 200 users and the shares and permissions.

    rendom is fine. I have used it for single domain forest so cannot say if it is OK with multi domain forests.

    But, you should take a backup of the domain/domain controllers.

    The rendom works best IMO. 2 years or so ago we had to rename because of the underscore wehadin ours.

    1500 workstations (including laptops) 9 domain controllers and approximately 20 other server including exchange 2003, MS SQL, and a clustered term server.

    We had around 1100 users.

    Our biggest issue was the random laptop that didn't get renamed because it was at the users house and the fix was a simple disjoin/join.

    Like was mention make a backup.
