I have a network (with multiple subnets) that is Windows 2k AD with five 2k BDCs. My Win2k Domain also has an Exchange 2k server running with AD.
I have a need to add a 2003 AD server for the purpose of authentication for a Internet Control/Content Filter. This device only works with Win 2003 AD.
So my question is, since I don't want to have to upgrade my Exchange 2k licenses, is it possible to add a Windows 2003 AD server on to my domain without making any changes to the Exchange server? Would I also need to upgrade all my BDC servers to 2003?
I realize that I would have run domain and forest prep prior to adding the 2003 server, but I want to know whether that would cause an issue with the 2k Exchange server running AD.
Basically can an Exchange server running 2k with AD co-exist in a 2003 domain?
My domain is in a mixed environment.
