Last year, I migrated from Exchange 5.5 to Exchange 2003 (on a Win2003 SP1 box), for which I recently installed SP2 (which caused havoc with OWA, but that's a different question). This is a multi-part question, involving 3 servers - Exchange 2003, DC1 (currently holding all FSMO roles), and DC2 (which I want to become the primary server in our single domain):
1) I notice that on my Exchange 2003 box, the ADC and Exchange 5.5 Admin are still there under Start/Programs/MS Exchange. Do I still need those? It isn't ADC that allows me to manage Exchange from Active Directory on my FSMO server, is it? If I can get rid of one or both of these, is there a preferred approach?
2) Speaking of my FSMO server, I now want to transfer all FSMO roles to DC2, and demote DC1 to a member server. Will any of this effect email? Currently on DC2, I do not see the Exchange tabs for users in ADUC.
