Hello Brian,
I had Googled this, too, when you first submitted the problem.

EMC support is unlikely to be your best approach, because this is a
problem
in Exchange Server.
I have found EMC's tech support to be very strong lately, especially
for Exchange.
You do raise a good point though. Anyone who has a persistent problem
with the NetWorker Exchange backup module should try using NT Backup
and also closely scrutinize the Exchange server's event logs and
perhaps start packet sniffing the Exchange server's network port.
I recently put an Exchange server backup problem to rest after a
solid month of daily troubleshooting. The EMC folks were very helpful
in that effort, even though the problem turned out to be a firewall
issue. We eventually threw up our hands and put a storage node on the
same side of the firewall as our Exchange server and backups have
been running fine ever since.
The idea to use NTbackup came from EMC and it too failed. So if
nothing else pans out, its worth a try. My Exchange server
administrator plugged a large USB disk drive into the server and
tried NT backup and it succeeded, but it failed on the same disk
drive when it was plugged into another Windows server on a different
subnet and backed up to it remotely. This is despite the fact that
our network guys insisted that nothing was wrong with our firewall
and even our own packet sniffing found only a handful of
retransmitted packets.
