I have ISA server in my Office but I need to create a Site and Content Rule for access and installs patchs and service packs from WindowsUpdate in some computers that don't have permissions to access other web pages, the only access allowed is to WindowsUpdate and OfficeUpdate sites. How can I create this site and content rule and what sites or ip address from Microsoft I need to configure for that purpose ??? Thank you for all you support and help you can give to me. Regards. jperez.
