I have migrated AD and DC/FSMO from my Windows Server 2003 to 2012 Datacenter. I have encountered a few errors along the way but was able to overcome them (by turning on Remote Registry Service) and verify at the end of the migration that my FSMO
roles have successfully transferred to new Win Server 2012 AD by running netdom query FSMO. The command returned a success response. I have used the following instructions to migrate DC and FSMO:

This one to transfer all the FSMO roles and retaering the old 2003 box

Once verified that migration of FSMO roles and Global catalog succeeded I moved on to migrating 2003 Exchange to 2010. After about 2 weeks, AFTER REBOOT, my 12 exchange services do not start and the Exchange Server is displaying Kerberos authentication
errorcode 0x80090311. Also it doesn't see the Active Directory Server.
I went on the 2012 Active Directory Server (which is a separate server from Exchange) and noticed that FSMO roles and global catalog have disappeared. No connection to global catalog yet I can still log into the domain. What did just happen?
Netdom query FSMO returns: The specified domain either does not exist or could not be contacted. The command failed to complete successfully.
Here are additional errors listed below:
The DNS server is waiting for Active Directory Domain Services (AD DS) to signal that the initial synchronization of the directory has been completed. The DNS server service cannot start until the initial synchronization is complete because critical DNS
data might not yet be replicated onto this domain controller. If events in the AD DS event log indicate that there is a problem with DNS name resolution, consider adding the IP address of another DNS server for this domain to the DNS server list in the Internet
Protocol properties of this computer. This event will be logged every two minutes until AD DS has signaled that the initial synchronization has successfully completed.

Active Directory Domain Services was unable to establish a connection with the global catalog.
Additional Data
Error value:
1355 The specified domain either does not exist or could not be contacted.
Internal ID:

User Action:
Make sure a global catalog is available in the forest, and is reachable from this domain controller. You may use the nltest utility to diagnose this problem.

This is the replication status for the following directory partition on this directory server.
Directory partition:
CN=Configuration,DC=BlaDomain,DC=Blalubber,DC=com
This directory server has not received replication information from a number of directory servers within the configured latency interval.
Latency Interval (Hours):
24
Number of directory servers in all sites:
1
Number of directory servers in this site:
1
The latency interval can be modified with the following registry key.
Registry Key:
HKLM\System\CurrentControlSet\Services\NTDS\Parameters\Replicator latency error interval (hours)
To identify the directory servers by name, use the dcdiag.exe tool.
You can also use the support tool repadmin.exe to display the replication latencies of the directory servers. The command is "repadmin /showvector /latency <partition-dn>".

The Knowledge Consistency Checker (KCC) has detected that successive attempts to replicate with the following directory service has consistently failed.
Attempts:
66
Directory service:
CN=NTDS Settings,CN=VIPMAIN,CN=Servers,CN=Default-First-Site-Name,CN=Sites,CN=Configuration,DC=BlaDomain,DC=Blalubber,DC=com
Period of time (minutes):

The Connection object for this directory service will be ignored, and a new temporary connection will be established to ensure that replication continues. Once replication with this directory service resumes, the temporary connection will be removed.
Additional Data
Error value:
1908 Could not find the domain controller for this domain.

Everything was working just a few weeks ago. What happened? I am confused. Any help is appreciated. Thanks in advance.
