"Restoring the Registry" Help topic in Regedit.exe or the "Restoring a

SYMPTOMS
========

When an application tries to open large files (over 100MB), the open request may
fail with one of the following error messages:

   Insufficient Resources

- or -

   Invalid Handle

The actual error returned varies depending on the application being used to open
the file.


RESOLUTION
==========

The allocation for paged-pool memory was modified to correct any problem that
might occur on systems that have large files (greater 100MB) that are repeatedly
opened sequentially, updated, and then closed.

Ntoskrnl.exe and Ntkrnlmp.exe have been updated to correct this problem.

WARNING: Using Registry Editor incorrectly can cause serious problems that may
require you to reinstall your operating system. Microsoft cannot guarantee that
problems resulting from the incorrect use of Registry Editor can be solved. Use
Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys And
Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete

   HKEY_LOCAL_MACHINE subtree:

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

   NOTE: The above registry key is one path; it has been wrapped for readability.

2. From the Edit menu, click Add Value.

   REG_DWORD.

4. Click OK and enter 1 as the Data.
