[Networker] RPC Errors backing up Windows hosts

Within the past month as we've started to add Windows hosts to our mixof backups with NetWorker Server version 7.3.2 running under Solaris 10,we've come across a number of cases where some particular volumes refuseto backup successfully. In those instances, the backup will startnormally, and after several gigs of data being transfered (seeminglyrandomly -- 10 GB one day, 200 GB the next) the following error isthrown every time:

* hyperion.ece.gatech.edu:F:\ save: RPC error: RPC send operationfailed. A network connection could not be established with the host.

The ONLY proposed solution that I have found for this condition has todo with erroneous DNS entries cached by the client that requiresflushing with an 'arp -d' and 'ipconfig /flushdns'. I feel this solutionis not appropriate in my situation, after all, the client has no problemstarting a new save session with the server until at least 1 hour ormore later...


Has anyone encountered something similar? We're running out of ideas!

Thanks in advance!
