SYMPTOMS
When you are running Windows 2000 with multiple monitors, the computer may run out of system page table entries (PTEs). PTEs are required to map the frame buffer.
WORKAROUNDWARNING: 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.
To work around this behavior, increase the number of PTEs:
- Start Registry Editor (Regedt32.exe).
- Locate the SystemPages value under the following key in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management
- Double-click the SystemPages value. The Edit DWORD Value dialog box appears.
- Type 36000, and then click OK.
- Quit Registry Editor.
STATUSMicrosoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
