How to Reinstall Proxy Server 2.0 Performance Monitor Counters (226543)

MORE INFORMATION

Three files are required to install Performance Monitor Counters for NTOP services. One file is a .ini file that contains the installation instructions for the counters, another is a .h file that contains the symbolic and offset information for the counters, and the third file is the .dll file that maintains the counters statistics. These three files must reside in the %windir%\system32 directory before they can be installed for use with Performance Monitor.

If the main Performance Monitor data files (Perfc009.dat and Perfh009.dat) have become corrupted, you can use the following article to correct the problem: The following table provides a list of all Proxy Server 2.0 Performance Monitor Objects, their corresponding .ini, .h, and .dll files, and their registry key name.

Object name	.ini file name	.h file name	.dll file name	Services registry key name
Winsock Proxy Server	Wspperf.ini	Wspperf.h	Wspperf.dll	WSPSrv
Web Proxy Server Service	W3pctrs.ini	W3pctrs.h	Mspmon.dll	W3proxy
Packet Filtering	Pfctrs.ini	Pfctrs.h	Mspmon.dll	Mspadmin
Web Proxy Server Cache	Cachctrs.ini	Cachctrs.h	Mspmon.dll	W3pcache

Use the following instructions to install or reinstall Performance Monitor Counters for Proxy Server 2.0 services:

1. To install an object's counters, the object's .ini, .h, and .dll files must reside in the %windir%\system32 directory. Using the above table determine which .ini, .h, and .dll files you need for the object you want to install. Determine if the .ini, .h, and .dll files are in the %windir%\system32 directory. If they are not, you can copy the files to the %windir%\system32 directory from the Microsoft Proxy Server 2.0 compact disc. The .ini and .h files can be found in the I386\Perfctrs or Alpha\Perfctrs directory and the .dll files are in the I386 or Alpha directory.
2. Open a Command Prompt and change the directory to %windir%\system32.
3. Type the following:

   lodctr <.INI File Name for Object to Install>

   If you receive the following message:
   Counters for <OBJECT NAME> are already installed
   Unable to update the system registry
   type the following:

   unlodctr <Services Registry Key Name>

   and re-type:

   lodctr <.INI File Name for Object to Install>

4. Repeat Steps 1 through 3 for each object that you want to install Performance Monitor Counters for.
