We strongly recommend that all users upgrade to Microsoft Internet Information Services (IIS) version 6.0 running on Microsoft Windows Server 2003. IIS 6.0 significantly increases Web infrastructure security. For more information about IIS security-related topics, visit the following Microsoft Web site:

SYMPTOMS
After you install Internet Information Server, counters will be added to Performance Monitor for the Internet Information Services Global, the HTTP Service, the FTP Service and the Gopher Service. These counters only appear when the corresponding services are running. These counters will only be available to administrators.



CAUSE
If the counters for these services do not show under any circumstances, there maybe a problem with the Performance Monitor counter information files. When Internet Information Server installs, it will create or modify the Perfc009.dat and Perfh009.dat files, and create backup files of Perfc009.bak and Perfh009.bak.



RESOLUTION
To work around this problem, first make a backup of the Perf*.dat and Perf*.bak files. Then copy the existing Perf*.bak files to Perf*.dat files. Make sure that Performance Monitor is not currently accessing these files.

Note: If the Perf*.bak files are corrupt, copy the Perf*.dat and Perf*.bak files from an existing working system with the same Performance Monitor counters installed.



STATUS
Microsoft has confirmed this to be a problem in Internet Information Server versions 2.0 and 3.0.
