The network connection to the Backup Exec Remote Agent has been lost

Hi,

We have Backup Exec 11d installed on a Windows 2003 server.   We're getting "the network connection to backup exec remote agent has been lost' error message everytime I include "Shadow Copy Components" in the file selection list.   Backing up just files and folders works fine.   

I was just trying to backup the local server, no remote servers included.   The local server replicates (via Microsoft DFS) with other  remote servers though that's why I need to select "Shadow Copy Components" so it would backup the replicated folders.   I have installed Remote Agent on the DFS replication partners servers but that didn't help.  No updates has been installed yet though.  I tried running LiveUpdates but it failed.

Any ideas on how to fix this?   

Any assistance would be greatly appreciated.

Thanks and regards,

Ratchet
