I have been using ISA server. Presently I am using it on Windows 2000 with service pack1. It has worked great so far. Now I am facing a problem. It does not open www.yahoo.com and www.hotmail.com. It opens other links in these sites. I have made no configuration changes from the time was ok, I mean I have created no site and content rule or anyother things like that. It worked ok initially but created this problem just after running 2 weeks. Please help me
