Hi, I have successful implementation of squid proxy with no issue. But today few Microsoft guys came for some presentation and wanted to connect http://212.109.109.221 but I get following message- "Web browser is sending a WWW-Authenticate header field that the Web server is not configured to accept" While connecting to through ISA proxy or directly through a dial up connection I get window prompt for username and password. Please let me know what change I should make in configuration so that IIS site with authentication other than anonymous can work ok.
