This problem occurs when the Application Center Request Forwarder Filter (fFiltExt.dll) incorrectly processes incoming HTTP 1.0 requests. The filter may incorrectly process these requests when the servers that are running Application Center 2000 communicate through a server that is running ISA Server.
In this case, the filter processes all forwarded requests as HTTP 1.1 protocol requests that have keep-alive connections enabled.
For example, when the filter processes incoming HTTP 1.0 protocol requests, it treats the HTTP 1.0 protocol requests as HTTP 1.1 protocol requests. It uses "keep alive" connections to try to maintain a connection to another server that is running Application Center on the other side of the server that is running ISA Server.
Therefore, the HTTP 1.1 protocol keep-alive connection request times out.

After you apply the hotfix, you must create the following key in the Microsoft Internet Information Services (IIIS) metabase. To do this, use the Mdutil.exe command-line tool. The Mdutil.exe command-line tool is located in the Support folder on the Application Center 2000 installation CD.
To create the metabase key, follow these steps:
- Click Start, click Run, type cmd, and then click OK.
- At the command prompt, type the following command, and then press ENTER:
mdutil.exe set AppCenter/Cluster -prop 57624 -dtype DWORD -utype 200 -value 0
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section. This problem was first corrected in Application Center 2000 Service Pack 2.
