The client lost its session to the server.

Error: %1

Server name: %5
Session ID: %2

Guidance:
If the server is a Windows Failover Cluster file server, then this message occurs when the file share moves between cluster nodes. There should also be an anti-event 30806 indicating the session to the server was re-established. If the server is not a failover cluster, it is likely that the server was previously online, but it is now inaccessible over the network.
