      Windows Server 2003 SP1 makes significant changes to the Remote Procedure Call (RPC) service. Some of the changes may cause conflicts with ISA Server’s RPC filter (rpcFltr.dll). As a workaround, disable the RPC filter. Install this update to fix this issue without disabling the RPC filter.

      In Small Business Server (SBS) scenarios, this may commonly occur when Outlook is installed on a server running Terminal Services in application sharing mode.
