Are you having Terminal Server (Remote Desktop Services) performance issues when logging on, redirecting printers, or the print spooler hanging? Eric Guo has a recent post outlining these performance issues can be due to; “hundreds or thousands of Inactive TS Ports”…..”in certain scenarios on 2003 Terminal Servers and 2008/2008 R2 RDS Servers.” The first server I checked had hundreds. He has provided a tool “InactiveTSPortList” on CodePlex that will allow you to list and/or delete the inactive ports (requires Live ID sign in):

Hi, I get “UNAUTHORIZED” when i click on the link above, Is there a link that we are authorized to use?.
The first link requires you create a signin ID. I have added a direct link to the Codeplex site. I hope that will be helpful.
