Required Files
You must have three files to install Performance Monitor counters for NTOP services. One file is an .ini file that contains the installation instructions for the counters, another is an .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, the following Microsoft Knowledge Base article describes how to correct the problem:

Installation Steps
To install or reinstall Performance Monitor counters for the NTOP services, follow these steps:  To install the counters for an object, the .ini, .h, and .dll files for the object must reside in the %Windir%\System32 directory. Use the table in this article to determine which .ini, .h, and .dll files you need for the object that you want to install. Determine if the .ini, .h, and .dll files are in the %Windir%\System32 directory. If they are not, you can use the latest version of WinZip to extract the files to the %Windir%\System32 directory from the appropriate .cab file on the NTOP compact disc. Open a command prompt and change to the %Windir%\System32 directory. Type the following:

lodctr 

If you receive the following error message:

Counters for  are already installed

Unable to update the system registry

type the following:

unlodctr 

and then re-type:

lodctr 

 Repeat steps 1 through 3 for each object that you want to install Performance Monitor counters for.
