(This feels a little ironic as in a previous thread I mentioned that we had few issues)
Networker 7.3 SP3 Build 510 on W2K3 server with a Dell (aic scalar) ML6200 library
We have an issue with some nightly backups, basically what happen is the job runs in the early hours of the morning, at some point during the backup, the console seems to "lose" connection with the server.
This gives very long periods between changing screens, somethimes the console reports that the job is still running when it has actually completed,
sometimes it partially fails to complete the backup, reporting that the job was "interrupted"
I have checked the logs for the time in particular and have found the following which may be of some use, any help advise would be appreciated
from Daemon.log
"01/31/09 05:16:33 nsrjobd: Jobs error: Unable to find record for job 183544 during an attempt to send message to it" and
"01/31/09 04:03:28 savegrp: RPC error: Connection lost with server 01/31/09 04:03:28 savegrp: Lost channel with the server (nsrjobd) 01/31/09 04:03:28 savegrp: group PROD DUMPS aborted. 01/31/09 04:03:32 savegrp: RPC error: RPC receive operation failed.

As the message in log is pointing our. You may have a connectivity issue. Check you connection, your DSN settings, Check Netsat result from server and clients. Check you OS logs as well on both server and client.
The trouble shooting section in the Admin Guide has a couple of sections on Network & Communication issues.
Also I have found SysInternals TCPView to be a great tool for helping troubleshoot Networker connectivity issues. Get it Here:- www.sysinternals.com Load it on server and clients and monitor TCP Connections in real time. Use it together with their Windows Process Explorer for deeper delving
