I have a full license for Exchange 2000 as well as 2003. We are running in AD native mode with a single server install of Exchange 2003. I have created another server on which I have installed Exchange 2000 SP3. I have successfully integrated this into my Exchange site. I have created the IM Virtual Server. I am ready to start testing this with users. Here is where I am unsure. Obviously the whole thing is held together via AD. Since IM isn't supported in EX 2003 the only place where I see the Exchange task to enable IM on a particular user is from ADUC that is on the Exchange 2000 server. Can I just assign that role to a user in ADUC even though the ability to do this only exists on that one server. I was concerned about negatively impating the schema. If I pull this server at some time in the future do I have to remove that role from each user first? Do I need the SRV record? I have only one server involved in the whole IM thing. Thanx...Jon
