If during the installation of Windows 2000, you:

- Have Setup format at FAT or FAT32 boot drive

- Have Setup install IIS in the same process

opening System Monitor to add counters will generate an Event Id in the Application log similar to:

<b>The configuration information of the performance library "C:\WINNT\system32\w3ctrs.dll"
 for the "W3SVC" service does not match the trusted performance library information
 stored in the registry. The functions in this library will not be treated as trusted.

The configuration information of the performance library "C:\WINNT\system32\infoctrs.dll"
 for the "InetInfo" service does not match the trusted performance library information
 stored in the registry. The functions in this library will not be treated as trusted.

The configuration information of the performance library "C:\WINNT\system32\aspperf.dll"
 for the "ASP" service does not match the trusted performance library information
 stored in the registry. The functions in this library will not be treated as trusted.</b>
This problem doesn't happen if you had chosen NTFS, or installed IIS later.

To resolve the problem:

1. Open a CMD prompt.

2. Type the following commands:

    cd /d %SystemRoot%\System32
    unlodctr w3svc
    unlodctr asp
    unlodctr inetinfo
    unlodctr msftpsvc
    lodctr w3ctrs.ini
    lodctr axperf.ini
    lodctr infoctrs.ini
    lodctr ftpctrs.ini
