I originally had the 120 day evaluation of ISA Standard installed and after purchasing the Full Version I installed over the top of the eval version. I attempted to install SP1 and was advised that "This fix package cannot be installed on the ISA Server 2000 Evaluation version". So I uninstalled ISA and reinstalled and then got the same message. Help, I really would like to get this install updated with SP1. Marc Lingenfelter
