Same installation problem
**** Moved to new discussion from https://www-secure.symantec.com/connect/forums/not-able-install-netbackup-client-software ****
I am facing exactly same problem (not able to communicate with master server, backups may not properly function) as zing said.
My client at DMZ zone (behind the firewall).
I follow your previous procedure.
1. Windows firewall is off.
2.Master & client can ping each other
2.Permit port 13724, 1556, and telnet at firewall at both direction
After that, Same problem exist.
But when I change the Firewall by permit any any (open for all port) then I can install the client without any error.
Now I need to know what are the ports are exactly needed to permit at firewall to communicate client and master server?
