Today I faced this issue this issue in my lab and thought of sharing

I had 2 domain controllers with exchange 2013 CU2 on windows 2012 servers.

To reduce the load on the server I decided to remove domain controller from one of the node so that I can reduce the hardware requirement.

-I uninstalled domain controller role and restarted the server.

-I was able to login to ECP but database mounting status was not clear

 

-Now I tried to mount the databases from shell but I got the below error.

[PS] C:Windowssystem32>Mount-Database “Mailbox Database 1213626026”

Failed to mount database “Mailbox Database 1213626026”. Error: An Active Manager operation failed. Error: The database action failed. Error: The Microsoft Exchange Replication service may not be running on server 2013VTC2.VTC2013.EDU. Specific RPC error message: Error 0x6ba (The RPC server is unavailable) from cli_AmMountDatabaseDirect3 [Database: Mailbox Database 1213626026, Server: 2013VTC1.VTC2013.EDU]

-Restarted “Microsoft Exchange Replication” Service but no luck

-Restarted “Microsoft Exchange Health” service but no luck

-Restarted the server but no luck

-Ran the test-replicationhealth and got the following error.

Error : The health test of the TCP listener for the Microsoft Exchange Replication service on server ‘2013VTC2’ failed. This server cannot participate in replication until the error is resolved. Error: Couldn’t determine the IP address for server ‘2013VTC2’ because DNS didn’t return any information.

-Checked DNS and there was no entry in it for this server.

 

-Added DNS Entry.

-Restarted “Microsoft Exchange Replication” Service but no luck

-Restarted “Microsoft Exchange Health” service but no luck

-Just realize I forgot to remove AD and DNS Roles from Add/remove role server.

-Removed AD and DNS component from remove role and features.

-Restarted the server and all came well.
