  Q256986 Description of the Microsoft Windows Registry

SYMPTOMS
========

If you have a computer running Windows NT 4.0 or later, some or all Remote
Access Service (RAS) and Routing and Remote Access Service (RRAS) counters may
be missing in Performance Monitor.

CAUSE
=====

This behavior occurs because of any of the following conditions:

- The Rasctrs.dll file is missing or corrupted.

- The Close, Collect, Library, and Open values are missing in the following
  registry key:

  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RemoteAccess\Performance

RESOLUTION
==========

WARNING: 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 resolve this issue, use the appropriate method:

- Delete the Rasctrs.dll file and replace it with the Rasctrs.dll file from the
  RRAS installation file or from the Windows NT 4.0 service pack CD-ROM.

- Add the missing registry values:

  1. Start Registry Editor (Regedt32.exe).

  2. Locate the following registry key:

  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RemoteAccess\Performance

  3. On the Edit menu, click Add Value, and then add the following registry
     values:

  Value 0
  Value name: Close
  Data type: REG_SZ
  Data: CloseRasPerformanceData

  Value 1
  Value name: Collect
  Data type: REG_SZ
  Data: CollectRasPerformanceData

  Value 2
  Value name: Library
  Data type: REG_SZ
  Data: rasctrs.dll

  Value 3
  Value name: Open
  Data type: REG_SZ
  Data: OpenRasPerformanceData

  4. Quit Registry Editor.

MORE INFORMATION
================

To extract the files from the RRAS installation file, type the command:
"mpri386.exe /T:<directory path> /C" (without the quotation marks), where
<directory path> is the folder in which you want to put the files.

This places all of the files in the folder that you specify. You can then copy
the missing file to the Winnt\System32 folder.
