WebProxy authentication for non domain machines - 22.Jul.2008 10:33:55 AM

In ISA Server 2000 if a non domain PC tried to access Internet via WebProxy then the user would be prompted for username and password on the domain.

I cannot get the same behavour to work in ISA 2006. I have Internal Web Proxy enabled for Integrated and Basic Authentication. I do not have the require users to authenticate as would have been the case in ISA 2000 - I blieve this is no longer required.

From a non domain client (e.g contractor) with Internet Explorer set to connect via proxy server the user just does not get Internet access (ISA 502 error code - page cannot be displayed - unreachable address)

I have firewall policy to allow access to Internet for members of the Domain created Internet Users Group

I had been working on this all day and have now come up with a solution since posting.

Used the script on http://msdn.microsoft.com/en-us/library/ms826234.aspx and set value to true :)

Yes, worked like a dream. I saved the scipt on the ISA server and then ran it with the True variable (e.g. script.vbs True).

Non authenticated users or users who are not members of the Internet AD group are now prompted for a username and password. Correct username and password gives them access - wring username and password gives the Proxy 502 error page.
