SYMPTOMS
If you use Performance Monitor to track Private Bytes and Virtual Bytes on a Terminal Services-based server, the Spoolss.exe service may show increased memory usage, and may use from roughly 75 percent to 100 percent of the processor power.
CAUSE
This issue may occur if Citrix Metaframe Independent Computing Architecture (ICA) clients connect to your Terminal Services-based server. If you run Citrix with an ICA client in a Terminal Services environment, printers such as a Hewlett-Packard DeskJet 895cxi are automatically created. This causes the symptoms that are described earlier in this article to occur.
RESOLUTION
To work around this issue, use either of the following methods.
Use an Earlier Driver from the Windows NT Server 4.0, Terminal Server Edition, CD-ROM- Create a local printer, install a Hewlett-Packard DeskJet 550 driver from the Base Windows NT Terminal Server Edition CD-ROM, and then delete the printer. The driver remains installed on the computer.
- Modify the Wtsuprn.txt file, and then rename it with an .inf file name extension.
Turn Off the Ability for Users to Automatically Create Printers If the Driver Is Not InstalledWARNING: 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. - Use Registry Editor (Regedt32.exe) to view the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Providers\LanManPrintServices\Servers - Add the following registry value:
Value name: AddPrinterDrivers
Value type: REG_DWORD
Value data: 1
