Missing Objects and Counters in Performance Monitor

• Microsoft Windows NT operating system version 3.1
• Microsoft Windows NT Advanced Server version 3.1
• Microsoft Windows NT Workstation versions 3.5, 3.51
• Microsoft Windows NT Server versions 3.5, 3.51
• Microsoft Windows NT Workstation version 4.0

SUMMARY

When you attempt to add counters to the chart in Performance Monitor, the list of objects and counters may be incomplete or blank.

MORE INFORMATION

The Performance Monitor object and counter names are stored in the "Counters" in this Registry Key:

   HKEY_LOCAL_MACHINE
    \Software
     \Microsoft
      \WindowsNT
       \CurrentVersion
        \Perflib
         \<LangID> (LangID 009 = U.S. English)

To restore the default list of counters and objects in Performance Monitor, do either of these steps:

• If you have Windows NT version 3.1:

        Delete all <LangID> subkeys except the 009 subkey.
  

        NOTE: As a precaution, save the Perflib subkey before deleting any of
        the <LangID> subkeys.
  

        WARNING: Using the 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 the Registry Editor can be solved. Use this tool at
        your own risk.
  

     In Windows NT 3.5 you cannot delete any of the <LangID> subkeys.

     Change your Language setting in the International dialog box Control
     Panel back to its original setting or to the setting that includes
     the complete list of objects and counters.

     The Performance Monitor system counter names and explain text have 
     been moved from the registry to two data files, PerfCxxx.dat and 
     PerfHxxx.dat, located in the %SystemRoot%\system32 directory. They 
     can be renamed and expanded off of the installation CD.
