To work around this problem, restart the Terminal Services licensing service so the expired license can return to the licensing pool.
Note You must wait 15 minutes after you restart the licensing service before the expired license is returned to the licensing pool, and the client can again log on to the Terminal server.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article. This problem was first corrected in Microsoft Windows 2000 Service Pack 4.
Terminal Services licensing has a thread that runs when the Terminal Services licensing service starts. This thread sleeps for 15 minutes when the Terminal Services licensing service starts, and then performs a cleaning operation where it returns expired licenses to the licensing pool. After it completes this operation, this thread sleeps for 24 hours, and then performs the cleaning operation again. It repeats this license-cleaning operation every 24 hours until the Terminal Services licensing service is stopped.
