My intelligent messaging filter quit working. When I selected the intelligent messaging filter tab I got the error "The operation completed successfully" Facility:Win32 ID no:C0070000 Microsoft Intelligent Messaging Filter. I was told that I needed to reinstall SP2 for exchange. When I tried to run the SP2 install I got a message that I needed to uninstall IMF. I uninstalled the IMF and rebooted the server and when I run the install of SP2 I get the same message that I need to uninstall the IMF. The system thinks it is still installed. Did I miss something?
