After upgrading our domain controllers to Windows Server 2012 our Exchange 2010 server was not allowing connections.  After a reboot it would not allow services to start and would not login completely, it would hang during login process.  After investigation we found Exchnage services trying were start and stopping.  Below are the erros and I'll post what we did to fix in an answer after this post.

To solve this we rebooted into safe mode and edited the registry keys for the domain controllers Exchange was trying to use.  To do this search the registry for the FQDN of the old Domain Controllers (picture with example attached).  This will be under HKLM\SYSTEM\ControlSet001\services\MSExchange ADAccess\Profiles\Default\UserDC1, UserDC2, UserGC1, and UserGC2.  We modified these entries with the correct Dcomain Controllers FQDN and rebooted.  Everything worked at that point.

Hope this helps someone!

Dont mind but you shouldnt be hardcoding Exchnage to use some specific DC as this will arise whenever this new server added will have issues or will be restarted
