I had a 2003 DC that crashed. I promoted a 2008 server to Domain Controller with DNS and DHCP server. All computers on my network are connecting to the new DC but Exchange gets stuck on PLEASE WAIT FOR USER PROFILE SERVICE. If I go into active directory and remove the user profile script and home folder then I can logon with the admin account. After it logs in none of the exchange services will start. I'm thinking this is a DNS server issue but not sure. I get to Errors in the DNS best practice analyzer and have found fixes that I applied but the errors are still present. The errors are below.
The Active Directory integrated DNS zone _msdcs.raptor.local was not found.
DNS queries for the Active Directory integrated zone _msdcs.raptor.local might fail.
Restore the Active Directory integrated DNS zone _msdcs.raptor.local.
The network adapter Local Area Connection does not list the loopback IP address as a DNS server, or it is configured as the first entry.
If the loopback IP address is the first entry in the list of DNS servers, Active Directory might be unable to find its replication partners.
Configure adapter settings to add the loopback IP address to the list of DNS servers on all active interfaces, but not as the first server in the list.
