You are no longer connected to the network
Posted on 2012-03-16
We are having a problem in our satellite office that I can't quite put my finger on. Our satellite office computers keep dropping from the network every 5 minutes with an error message in the bottom right corner ...
You are no longer connected to BCR.local. You can continue working normally.
Details: The network is not available. If this is unexpected, check your network connection. You may continue working normally with offline files. Changes to any offline files will be copied back to computers on the netwrok when you synchronize.
We use folder redirection so it might be complaining about that. While this is happening they can still browse the web and other stuff -- just the network resources get dropped and mapped drives disappear.
The satellite office has it's own domain controller so I don't understand why it computers are displaying the "network errors" even if the VPN tunnels drop momentarily.
Our main office is connected to the sattelite office using site-to-site VPN tunnels. Each office has a SonicWall device. The main office has a SonicWall NSA 240 (1 yr old), and the sattelite office has a SonicWall TZ 170 (10 yrs old). We are going to replace the SonicWall TZ 170 soon, but that's not the point. The VPN tunnels only drop for a few seconds and reconnect automatically.
The question is: Why do the computers say the network (BCR) is not available when there is a local Domain Controller? Why is trying to reference Domain Controllers and other resources in our Main Office?
