I believe this is caused by Windows sending a CTRL_LOGOFF_EVENT to the service - http://msdn2.microsoft.com/en-us/library/ms683242.aspx has some details. Adding your own handler for this notification may allow you to prevent the problem, but I don't have the time at the moment to experiment with that.
