Good evening Tommy 
 
Tracking tcp/ip errors always seems  hard. 
Did you see any errors in the windows event logs, either system or application?
 
When we were looking at an ms exchange problem, the veritas tech support folks 
said that some drivers for interface cards could cause problems. You might want 
to check with  tech support and dell tech support. Our problem was not that, 
but a problem with the motherboard. 
 
Like others, I would ask for a little more info on what you mean by shutdown. 
Does all tcpip traffic stop, or just new connections? 
 
Almost everything netbackup does, seems to have a socket connection in the 
middle of the action. If you can you might check with the netstat command and 
see if you have a large number of socket connections in a time-wait state. 
If so you might want to look at changing the tcp_wait interval. At least it was 
a problem/fix on unix. 
 
Good luck and let us know the final fix.

        We are experiencing some unusual network connection problem between the
        NBU master server and NBU media servers. Once the backup jobs kick off,
        all the NetBackup server's network connections shutdown. Does anyone
        know any fix?

        Thanks
