Cause

Potential corruption occurred during the upgrade process on the media server.
 

Solution

Attempt to verify the following:

• The media server services have been restarted
• The bpclntcmd -pn and -hn works from media server and master
• The nbemmcmd -listhosts gives the media server name in the output
• The telnet is working from both end for shortname and fqdn
• Check if the install log (%ALLUSERSPROFILE%\Symantec\NetBackup\InstallLogs\) contains errors
• Delete the host_cache, disable IPV6, ensure binding order for NIC card is correct
• Add the media server entry in the registry or bp.conf of the master server

If all steps fail to correct the issue, perform a clean install of NetBackup on the media server
