PRB: Operation Is Excessively Slow When You Start the IIS MMC or Explorer.exe to Retrieve Directory Properties (319179)
The information in this article applies to:
- Microsoft Internet Information Server 5.0
This article was previously published under Q319179 SYMPTOMS
When you start the Internet Information Services (IIS) Microsoft Management Console (MMC) or attempt to use Explorer.exe to retrieve properties on any directory, this operation may be excessively slow.
CAUSE
This behavior can occur if the PHP hypertext preprocessor (Php4isapi.dll) is installed as an Internet Server Application Programming Interface (ISAPI) filter in IIS. PHP is loaded as an ISAPI filter in IIS. The version of PHP that exhibits this problem is 4.1.0. Php4isapi.dll does not contain file version information. The following is the internal time stamp of the version of Php4isapi.dll that exhibits this behavior:
RESOLUTION
To resolve this issue, remove the ISAPI filter (Php4isapi.dll).
For information about how to use the PHP executable program instead, browse to the following Web site:
MORE INFORMATION
The IIS MMC and Explorer.exe have threads waiting on the inetinfo process. Inetinfo attempts to close a metabase handle, but one of its threads stops responding (hangs) when it attempts to notify all of the sinks registered for metabase close notifications.
Explorer.exe is affected because it attempts to load W3ext.dll, the IIS shell extension.
