In our school district, we have Exchange 2003 installed on one of six servers. Four are DCs but not the Exchange server, but it does have AD. The mix is 1-2000, 3-2003, and 2-2008 server software. How can I get the ADs on the 4 DCs to show the Exchange 2003 schema (with email tabs)?

Hello Winston, You need to install Exchange SystemManagement Tools to get Exchange tabas on your DCs or Windows XP machines... How to Install the Exchange System Management Tools

Do I do this on each server? Thanks for answering.

Yes, on all servers wherever you want Exchange related tabs on AD objects... You are welcome...
