Network connection to Remote Agent has been lost

[James_Leo]

Every night for 6 nights the back up has failed. After backing up the majority of the data, the backup fails and I notice that the Backup Exec services have stopped. The last entry in the job history says "The network connection to the Backup Exec Remote Agent has been lost. Please check for network errors.
A timeout occurred waiting for completion of media server data processing". It was trying to backup the Exchange information store\First storage group at the time.
I restart the services and the next night the same thing happens.
Thanks
James

I would suggest install SP1:
VERITAS Backup Exec (tm) 9.1 for Windows Servers revision 4691 - Service Pack 1.
http://support.veritas.com/docs/267180


Enable restrict anonymous key on media as well as remote data server.
How to enable support for "Restrict Anonymous" when using Backup Exec 8.6 and 9.x for Windows Servers.
http://support.veritas.com/docs/238618



Try to backup again.




Note:Make sure the remote agent build on the remote server and the media server build should be same.





Please refer to these related technotes:

I will install SP1. However, this problem just suddenly started to happen last week. Plus there is no remote server. It is just a SBS 2000 server.
Thanks

In order to troubleshoot the problem, kindly refer the following steps mentioned in the technote given below.


Title:-"A timeout occurred waiting for data from the agent during operation shutdown" or ". Check for network errors" (a00084f8 HEX or e00084f8 HEX) is reported during a backup operation http://seer.support.veritas.com/docs/258159.htm
------------------------------------------------------------------------


Another step we would like to mention you that, while carrying out each of the Backup's of C: and D:, kindly make sure that SGMON is running in background.


Keep SGmon running while starting the remote agent OR Set SGmon enabled to 1 under HKEY_LOCAL_MACHINE\SOFTWARE\VERITAS\Backup Exec\Debug while starting the remote agent( Steps to start SGMON is mentioned in below point number


2) Please let us know the outcome of backup jobs once you start SGMON before carrying out backup job operation. Do you still come across any error messages or the remote agent service still hangs.


To isolate the problem, kindly carry out a test backup on Backup to disk folder and verify the result of the same.
For more information on Backup to Disk folder, you may refer to Administrator's Guide VERITAS Backup Exec (tm) 9.1 for Windows Servers Administrator's Guide (English) http://seer.support.veritas.com/docs/266190.htm
( Refer from page number- 149, Using Backup to Disk folders and files )

We hope this helps, In case if the problem still persists please revert back with the following information

1) Title:-How to enable or disable "debug logging" in VERITAS Backup Exec 9.x for Windows Servers on the Windows NT 4.0, Windows 2000, Windows XP, and Windows 2003 platforms http://seer.support.veritas.com/docs/254212.htm


2) SGMON.LOG file - The SGMON.EXE file located by default in \Program Files\VERITAS\Backup Exec\NT folder. Start sgmon.exe just before starting the backup job, this helps us see the sequence of events. Refer to the following technote:
