Issue
When you start Vista workstation that is receiving an license to run from another PC the path to this PC is lost each time Vista workstation is shut down.
Environment
Window 7
Server 2008
Cause
The User Account Control Setting is set too high preventing the license path being saved.
Resolution
Drop the user account control setting level down to allow the license server path to be saved.
From the Windows Start menu option type "User Account Control settings" in the "Search programs and files"
Then decrease the security level.
