We have two seperate Windows 2003 domains. Each has a single domain controller. Let's call the domains dom1 and dom2, and the servers srv1 and srv2.
srv1 is the domain controller for dom1. All our users log onto dom1. All the accounts and permissions are there.
srv2 is the domain controller for dom2. No users log onto this domain anymore, it's mostly retired. However, we do still have a lot of files here. So the server acts mostly like a file server. Permissions are setup based on dom1\username. So no local permissions or accounts are stored on dom2.
I'd like to decomission dom2, and make srv simply a file server for dom1.
What do I need to do to make that switch? Should I just join srv2 to dom1? Or do I need to shut off Active Directory on srv2 first, to retire dom2, then join it to dom1?
