What is the impact on an Exchange server when moving FSMO role and schema master into another DC? What do we have to do on exchange after performing a such task?

I had 1 DC (Windows server 2008 R2), 1 Exchange 2010 SP3. I install a new DC (Windows server 2008 R2). I then move all the FSMO role including the schema master role into the NEW DC. I check to be sure that the new DC is a GC as well.

I shutdown the old DC and my Exchange server was not working properly and specially Exchange Management Shell. It start working again after I turn up the older DC.

I am wondering why Exchange did not recognize the new DC, even after moving all the roles on it.

I am looking to hearing from you guys.

Thanks a lot

if you only have 1 DC, you might need to cycle the AD Topology service after shutting the one down.

Also, take a look in the windows logs, there should be an event where Exchange goes to discover Domain Controllers, make sure both are listed there.  You can probably force that by cycling AD topology (this will take all services down so be careful when you do it)
