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.
