bpkeyutil command resolved the socket issue when encryption was configured properly.
I see that the Master is also the Media Server
So you need dcbus01.corp.DOMAIN.org to be able to resolve UC4V8.corp.DOMAIN.org and vice versa
What we need is the bpcd log file from the client - it most probably cannot resolve the Master (or even does not have NetBackup running)
Create \program files\veritas\netbackup\logs\bpcd on the client and then just see if you can connect to it via the Hosts Properties - Clients section of the Admin Console on the Master Server
Post the clients bpcd log once you have done this - if one is not created then the Master is not communcating with the Client at all which could be name resolution, NBU Service not running on the client, firewall etc.
