Excessive Port Denies
We recently got a complaint from our Information Security Office indicating that our Master server was attempting to connect to all of the virtual machines in our virtual environment over port 137. ...
I donit think it was NetBackup "per se" that was using NetBios. I think it was Windows TCP stack with NetBios integration. You will always have this problem when NetBios is enabled on Windows based NIC, because not only is TCP and DNS doing name lookups - but Windows itself... when NetBios is enabled... is being opportunisitc and also trying to communicate to establish NetBios channels. It's not NetBackup, it's "Windows" networking - that's just the way it is and it's doing exactly what it's meant to do when NetBios is enabled on an interface.
You've done the right thing to turn it off when it's not required. So, turn it on to do your updates, if you need to, and turn it off again afterwards.
