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, 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.
