Every time you start Performance monitor and add a counter, an error is written to the Event Viewer in the application log including the following information:

   Source      Category    Event    User
   perfctrs    None        4005     N/A

   Event detail:
   Load of required DLL failed. Make sure the DLL file is in the PATH.
   DOS error number is returned in the data

   Error number : 0000007E


Performance Monitor needs the dynamic-link library (DLL), INETMIB1.DLL, in order to monitor TCP/IP counters. When you install the TCP/IP protocol in the Networks section of Control Panel, INETMIB1.DLL is not installed.


To install INETMIB1.DLL, perform one of the following procedures:

  • From the Networks section of Control Panel, install the SNMP Service.
  • Expand the INETMIB1.DLL file from the CD-ROM to the SYSTEM32 directory. For example:

          expand d:\i386\inetmib1.dl_ c:\winnt\system32\inetmib1.dll
