Exchange 2010 and AD Issue
Scenario
DC1 - Exchange 2010 /DNS/GC
DC2 - DNS/GC - PDC
DC3 - DNS/GC
I am currently working on demoting DC1 as a domain controller and leaving just for Exchange server. As a first test I have stopped the ADDS service on DC1 and hoping the exchange to work using the other DCs.
Webmail worked fine but outlook got disconnected and kept on asking for credential. Also active sync stopped working on the mobile devices.
So far Exchange is not pointing to DC1.
Am I missing something here or need to look for more things before I do another test.
What are the other things I should consider.

No FSMO roles are on DC2 and DC3
You absolutely cannot promote or demote a domain controller after exchange has been installed. It does break and there is no way to restore the functionality.

cgaliher,
Is the reason that I cannot demote/promote a domain controller due to the fact that AD and Exchange were installed on the same machine?
I have seen tutorials floating around where is was done when the AD and Exchange were on seperate machines.
Thanks
