Any idea what causes this error: "The view connection server connection failed. The handle is in the wrong state for the requested response." ?????

When I'm using the view client from home with our corporate VPN, I get the following error about 25% of the time: "The view connection server connection failed. The handle is in the wrong state for the requested response." I usually end up restarting the View client, start/stop VMware services, etc. and eventually it works. Not sure what causes it, because as Isaid, it doesn't happen everytime.
