Hi Tom, Is Microsoft going to fix this problem? Any suggest what we should do now? We need to replace CISCO PIX with ISA 2004 for all the new feature it provides. Is there any work around we can do to make this work? except joint the ISA server to the domain which is not allow by the company. I have ISA Server 2000 book. When the ISA server 2004 book will be publish? Thanks, Wendy
