Q242302: Poor Server Performance with High CPU Usage on Terminal Server

The information in this article applies to:

- Microsoft Windows NT Server versions 4.0, 4.0 SP5, Terminal Server Edition 
-------------------------------------------------------------------------------

SUMMARY
=======

Poor server performance may occur on computers running Windows NT 4.0, Terminal
Server Edition that have a large number of concurrent users running Microsoft
Word, Microsoft Excel, and Microsoft Internet Explorer as well as a large number
of NetWare printer queues. Symptoms of poor server performance can also be
observed by running Performance Monitor.

MORE INFORMATION
================

The CPU utilization and thread counts for the Services.exe and Spoolss.exe
processes appear higher than normal and their values fluctuate when you view
them in Performance Monitor. These fluctuating values would suggest that a large
number of threads are being dynamically created and eliminated.

This type of performance issue has not been observed when the Terminal Server
computer is configured with only Windows NT-based printer queues.

Creating local printer queues that send print jobs to the NetWare printer queues
through a UNC path can significantly reduce processor usage. To create a local
printer that sends print jobs to a NetWare printer queue:

1. Click on the Start, point to Settings, click Printer, and then double-click
  Add Printer.

2. In the Add Printer Wizard, click My Computer, and then click Next.

3. Click Add Port.

4. In the Printer Ports dialog box, click Local Port, and then click New Port.

5. In the Port Name dialog box, type a UNC path representing the NetWare printer
  queue. For example, \\Nw312\Myqueue.
