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: The following table provides a list of all NTOP Performance Monitor objects, their corresponding .ini, .h, and .dll files, their registry key name, and the .cab file on the NTOP compact disc where the files are located:

Object Name	.ini File Name	.h File Name	.dll File Name	Services Registry Key Name	.cab File Name

Installation Steps

To install or reinstall Performance Monitor counters for the NTOP services, follow these steps:

1. 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.
2. Open a command prompt and change to the %Windir%\System32 directory.
3. Type the following:

   lodctr .ini file name for object to install

   If you receive the following error message:
   Counters for object name are already installed
   Unable to update the system registry
   type the following:

   unlodctr services registry key name

   and then 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.
