SYMPTOMS
When a client computer connects to a Windows 2000-based computer that is running Terminal Services, the client's redirected printer may contain multiple session IDs in the name.



CAUSE
This problem may occur if a race condition exists during the creation of a printer queue and listening on the printer port.



RESOLUTION
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.
