I am having a issue with a Windows Client not backing up, I installed the NBU 7.1 client on a Windows 2008 server but's its not connecting to the master server.
When I go to host properties then client the client list then SELECT the Client I get the following
“cannot connect on socket”
I can ping the client from the master server and I can ping the client from the NBU master servert
The firewalls are turned off can any give me some advice on what I might try to solve this issue?
Thanks

Thanks to all who responded!
It turns out the IP address the clien was using needed to be put in the firewall rules after all.

Ensure the NetBackup Client service is running on the client
Check that the client can resolve the master to the correct IP and the IP resolves back to the correct master name.
Check that the master server can resolve the clients hostname to the correct IP address and it can resolve the IP address back to the client name.
Run this from the Master
bptestbpcd -client <clientname> -verbose
what is the result?
telnet <client> 1556
telnet <client> 13724
Does it connect?

Thanks revaroo,
when I ran this >>> bptestbpcd -client <clientname> -verbose from the master I got the following
[root@nbuserver2 ~]# bptestbpcd -client daylight1.dov.state.ny.us -verbose
<16>bptestbpcd main: Function ConnectToBPCD(daylight1.dov.state.ny.us) failed: 25
cannot connect on socket
I ran the following from the master also
telnet <client> 1556
telnet <client> 13724
here are the results
root@nbuserver2 ~]# telnet daylight1 1556
daylight1/1556: Name or service not known
[root@nbuserver2 ~]# telnet daylight1.dov.state.ny.us 1556

Have you tried traceroute and ping. You need to look at netstat and other networking troubleshooting techniques. This is obviously not an NBU problem, but a network problem. Few people realise that NetBackup is one of the best network trouble finders. :)

First of all ensure that Windows Firewall is indeed disabled on the client.
Confirm that the following services are running on the client:
NetBackup Client Service
NetBackup Legacy Client Service
NetBackup Legacy Network Service
Symantec Private Branch Exchange
When forward and reverse lookup has been confirmed between server and client using nslookup with hostname an ip address in both directions, do the following:
Create bpcd log folder on client in <install-path>\netbackup\logs.
Run the following on master/media server:
bptestbpcd -client <client-name> -verbose -debug
Please post output of bptestbpcd as well as client's bpcd log file.
If client cannot resolve server IP address to valid hostname that appears in Client's SERVER list, either fix reverse lookup in DNS or add server to client's hosts file.
