I have a problem when entering the NetBackup console with administrator privileges shows me the following error:
Unable to read configuration cannot connect on socket (25)
I appreciate your help.
Looks like your master unable to read its own configuration. Possibly due to name resolution problem.
Verify whether you have changed the hostname or ip on hostsfile or DNS. Just try bpclntcmd -clear_host_cache and then verify.
First of all check if all servecies are running. If they do, double check master-server name (resolving, FQDN). In the regestry check HKEY_LOCAL_MACHINE\SOFTWARE\Veritas\NetBackup\CurrentVersion\Config\ and ensure that following keys EMMSERVER snd Server have correct values.
