I have a Windows 2003 and 2000 Server mixed environment operating in Windows 2000 native mode. 2 of the Windows 2003 servers are DCs, and one Windows 2000 server is a DC. I want to migrate any of the operation masters/roles from the 2000 server to the 2003 dcs in preparation for demoting the 2000 DC. Currently, the 2k machine is a global catalog and one w2k3 machine is a global catalog. The 3rd dc (w2K3) is not a global catalog. Here are my questions:
1. I want to remove the global catalog off of the 2k machine. Will this cause any issues?
2. Should I make the other 2k3 DC a global catalog once I take the role away from the 2k machine? The 2k3 dc that is not a global catalog has exchange 2003 running on it. That way I will have 2 global catalogs.
3. Should I make the 2k3 dc a global catalog before I remove the role from the 2k machine?
4. Once I demote the 2k server, I will have 2 W2K3 servers with Active directory on them. What roles should be on which servers? One of the 2k3 DC servers is running exchange 2003 on it as well. I don't know if that changes anything.
Thanks for the quick replies.
