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:

IMPORTANT: This article contains information about editing the metabase. Before you edit the metabase, verify that you have a backup copy that you can restore if a problem occurs. For information about how to do this, see the "Configuration Backup/Restore" Help topic in Microsoft Management Console (MMC).


After you upgrade from Internet Information Server 3.0 to 4.0 or install the Windows NT Option Pack, the Active Log Format drop-down list box in Internet Service Manager appears empty. The problem persists even if you have reregistered the DLL files as specified in the following Microsoft Knowledge Base article:

183733 Active Log Format Drop-down List Is Not Populated After Upgrading to IIS 4.0


The LM/service name/Info/LogModuleList key in the metabase for the service does not match the string found in the key with the subkey names of the LM/Logging/log format. These strings are case-sensitive.


The process displays information in the Active Log Format drop-down list, whether or not the correct registration of the DLL and OCX files has occurred as specified in 183733.

WARNING: If you edit the metabase incorrectly, you can cause serious problems that may require you to reinstall any product that uses the metabase. Microsoft cannot guarantee that problems that result if you incorrectly edit the metabase can be solved. Edit the metabase at your own risk.

NOTE: Always back up the metabase before you edit it.

The subkeys of LM/Logging/log format should contain the Clsid (such as A9E69610-B80D-11D0-B9B9-00A0C922E750) for the LogModuleId and the LogModuleUiID options in order to load the right key in the registry. You must also register Iislog.dll, Logui.ocx, and Iscomlog.dll. In this case, the Properties button displays each log format.
