  0020: 00000000 00000000

CAUSE
=====

The default system pages of 10,000 are not enought for the server due to many
pages being locked down during transmission.

RESOLUTION
==========

To work around this problem, increase the number of system pages for the server
in the registry.

WARNING: Using Registry Editor incorrectly can cause serious, system-wide
problems that may require you to reinstall Windows NT to correct them. Microsoft
cannot guarantee that any problems resulting from the use of Registry Editor can
be solved. Use this tool at your own risk.

1. Start Registry Editor (REGEDT32.EXE) and locate the following Registry subkey
  in the HKEY_LOCAL_MACHINE subtree:

  \SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management

2. Select SystemPages. From the Edit menu, select DWORD.

3. For Data, enter 20000 (Decimal).

4. Click OK and quit Registry Editor.

5. Shut down and restart Windows NT.

STATUS
======
