Network communication failed - RS 8.1

[Richy_Boy]

Hi all;

 

I wonder if any of you see this error? I see this quite often in my logs.. The backup server and clients are on the latest drivers and I can't find any network switch errors.

 

I had been assuming it was proactive laptop users getting fed up with the disk thrashing and unplugging their laptops form the network but after seeing it happening on static desktop machines too I have checked a few users and they haven't unplugged for the full working day.

 

It does seem to be only happening with proactive backups though...!

-519 happens when the client disconnects from the network. This can happen when:

* The user shuts down the computer

* The user unplugs the network cable

* The client computer goes to sleep/hibernation

* The user connects to another network (such as a cellular network).

* The user connects via VPN to another network.
