Backups failing Windows server 2012r2

Hi, I recently migrated to server 2012 and have been having issues with networker backups. Unable to start networker remote exec service and snapshot mgmt service. Also i am unable to open nsradmin. when i try to open nsradmin, this is the output: 

C:\>nsrports

173680:nsrports: RPC client handle: No connection could be made because the targ

et machine actively refused it.

172089:nsrports: Unable to create the connection with 'portmapper' to host 'loca

146730:nsrports: Unable to connect to nsrexecd on host ________: Remote

system error - No connection could be made because the target machine actively

refused it.

 

 

This is the what i found in the daemon log;

nsrexecd RAP critical Attributes 'name' and/or 'my hostname' of the NSRLA resource do not resolve to the machine's hostname 'wpccda02.upgf.com'. To correct the error, it may be necessary to delete the NSRLA database.

 

Please advise!
