Domain Rename

Posted on 2012-04-02

We are currently running our domain in a 2008 R2 enviroment.  For whatever reason, the previous network admin named our domain, cyfairfcu.org, which is the same as our website.  This is causing DNS problems in addition to other oddities.  I'm wondering what the risk or advice would be to rename the domain from cyfairfcu.org to local.cyfair (or simular).
What will renaming the domain effect? Permissions, user accounts?


Please advise, as I've never done this before.

If it is, you will have an easier time migrating to a brand new domain. Run them in trust, migrate, delete old domain

If you don't have any software that doesn't support a domain rename, you can do it. Depending on the problems you're experiencing, however, there are usually ways to work around the problems that occur when the internal domain is the same as the external domain. It'll probably be less drastic and less of a hassle to just work around the problems you have than it is to rename or move to another forest (especially on a Credit Union network :S)

That said, http://technet.microsoft.com/en-us/library/cc794907%28v=ws.10%29.aspx has some good info on doing a domain rename. Look through it and see if it's feasible in your situation.
