Resolving "Workstation already in use" network errors

When starting up a Campground Master client workstation, you may occasionally experience the message that its Workstation ID is already in use.

Correcting this usually requires a restart of the Master workstation, or at least a Stop/Start of the server task (through Maintenance / Network Functions on the master).  

The cause of this is usually a Windows network glitch that causes the connection "socket" to disconnect without proper notification to the Campground Master.  This can be more common in wireless networks where glitches can be more frequent.  

However it can also happen if the client requests a full database refresh when it starts up (a timing issue causes it to reconnect too quickly, especially in versions prior to 3.6), so if it keeps happening even after rebooting the master then try restoring the client's database from a backup (from the master) to make sure they're in proper sync -- this will keep it from requesting the full database on startup.  

Also, make sure Network Setup option "Request full database update very time connected" is not selected.  (In recent versions, this is on the Diagnostic Options tab of Network Setup.)
