IMPORTANT: This article contains information about editing the registry.
Before you edit the registry, make sure you understand how to restore it
if a problem occurs. For information about how to do this, view the
"Restoring the Registry" Help topic in Regedit.exe or the "Restoring a
Registry Key" Help topic in Regedt32.exe.

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.

To resolve this problem on Windows NT 3.51, obtain and install the hotfix. You
must restart the computer for the fix to take effect. No registry changes are
required on Windows NT 3.51.

Windows NT 4.0
--------------

To resolve this problem, obtain the latest service pack for Windows NT 4.0 or

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
Information in the Registry" and "Edit Registry Data" Help topics in
Regedt32.exe. Note that you should back up the registry before you edit it.

1. Start Registry Editor, locate and select the following Registry subkey in the
  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.

3. Enter DisablePagedPoolHint as the value name and set the Data Type to
  REG_DWORD.

4. Click OK and enter 1 as the Data.

5. Click OK, quit Registry Editor, and then shut down and restart the computer.
