We have this configuration without major issue, but it is primarily UNIX
environment (though with 4 windows media servers).

Does your Netbackup NIC have its own DNS name and are the media
servers/clients referring to this as their master?  You may also need to
set up manual routes so that replies from the master go out that NIC,
otherwise a client might get a reply from the other NIC/DNS name and not
recognize it as the master.

Subject: [Veritas-bu] [NBU5.1MP3 W2K3] communication errors

Hi there,

We have one Master Server and three Media Servers. The Master Server is
in another location then the two Media Servers.

All the servers have 2 NIC's. Let's call the first NIC "backup" and the
second NIC "users"

Al the clients have the "use specified network interface" setting
configured under host properties using the "backup" interface

The Master and Media Servers can only communicate over the "user" NIC.
So that's the other NIC then the clients use to backup their data.

At this moment we get lot's of communication errors between the Master
and Media Servers (cannot write to socket, invalid error number etc) and
bpsched is crashing and the Windows Event log is logging all kinds of
bpsched application errors.

Does anyone has this kind of configuration (clients backup to one NIC,
NetBackup communication over another NIC) working without errors?
