I recently did an Exchange 2010 migration from Exchange 2003. Everything is working appropriately and the Exchange 2003 server was successfully removed. During the migrations there were several bumps along the way and during troubleshooting a command was entered that forced the Exchange server to look at only one of the domain controllers. Now, if I reboot the domain controller that Exchange is looking at (DC01) all of the endusers are unable to connect to the Exchange server via Outlook.
I need the command that will let Exchange see both DCs which hold the GC role so when one DC is rebooted Outlook users can still send and receive email.
Thank you in advance.
