APPLIES TO


 * Microsoft Application Center 2000 Standard Edition

This article was previously published under Q312366



SYMPTOMS
When you install Application Center 2000 on a FAT32 partition on a cluster controller, and Application Center 2000 replication replicates the Request Forwarder DLL (RFFilExt.dll) to a cluster member that has Application Center 2000 installed on an NTFS partition, then the Inetinfo.exe process throws an access violation.



CAUSE
Application Center 2000 replication replicates global ISAPI filters. Request Forwarder has one DLL (RFFilExt.dll) that is both an Internet Information Service (IIS) extension and a filter. Because RFFilExt.dll is an extension, you must allow Read and Execute permissions for Everyone.

When Application Center 2000 replication replicates RFFilExt.dll to a cluster member that has Application Center 2000 installed on an NTFS partition, the replication overwrites the access control lists (ACLs) on NTFS, which removes the necessary permissions if you do not set the correct permissions on the cluster controller.

NOTE: A security lockdown may also strip these permissions.



RESOLUTION
Set Read and Execute permissions for Everyone for RFFilExt.dll.



STATUS
This behavior is by design.



Steps to Reproduce Behavior

 * 1) Create a Web cluster that has the cluster controller on a FAT32 partition and the cluster member on an NTFS partition.
 * 2) Enable Request Forwarding.
 * 3) Force a synchronization on the cluster.
 * 4) Under the debugger, stop and start the Inetinfo and W3svc services on the cluster member. The access violation occurs after a few minutes.
