Hello I can't browse from ISA server. The ISA server primarily used for publishing the internal web sites to the Internet. The ISA server sits behind the CSS (Cisco content switches). ISA has 2 NIC, external and Internal. Internal NIC is configured with DNS. The system policy to get to the listed sites is enabled on the server. Web proxy setting is enabled on the internal network. I configured the browser on ISA server to point to internal IP of the ISA server (web proxy client settings). The resolution for the sites works fine. The browsing from the ISA server to specific site is required to retrieve third-party root list sequence number from <http://www.download.windowsupdate.com/msdownload/update/v3/static/trust edr/en/authrootseq.txt for the certificate hat is used to publih a secure site on ISA server. Any thoughts? Thanks Shobha Pandey MCSE Integration Consultant Enterprise Server Farm Office Of Administration HelpDesk: (717) 506-1079 email: c-ssharma@xxxxxxxxxxx
