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

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:

Before you modify the registry, make sure to back it up and make sure that you understand how to restore the registry if a problem occurs.

SYMPTOMS

After you upgrade from Internet Information Server (IIS) 3.0 to IIS 4.0 or install the Windows NT Option Pack, the Active Log Format drop-down list box in Internet Service Manager (ISM) is empty or not populated.

CAUSE

IIS 4.0 uses a new logging format that is extensible. You may have to re- register some of the logging DLL files, if the Setup program does not register them.

NOTE: The logging modules are implemented as COM objects.

WORKAROUND

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

To restore the list of log formats, run the following three commands from a command prompt in the <%SystemRoot%>\System32\Inetsrv directory:

   regsvr32 iislog.dll
   regsvr32 iscomlog.dll
   regsvr32 logui.ocx
   regsvr32 cnfgprts.ocx

MORE INFORMATION

To locate the Active log format drop-down list box in the ISM, view the properties of a web site, and then click the Web Site tab.
