The outgoing web request listener is bound to port 80. The article Q305204 refers to the problem. Althout I have installed SP1, the problem persists. I don´t want to uncheck "Ask unauthenticated users...", ´cause doing so I get anonimous access in my report (even though no unauthenticated access is passing through ISA). Tks Jim. The difference is in how the request is made. for the configuration script, the client is asking the ISA for a local resource (the config file) for a web request, it's asking ISA to "fetch" the website for it. You have the user going to :80 for the config script; where is the outgoing web request listener bound?

It seems that Integrated authentication is not working right. We configured Integrated authentication and "Ask unauthenticated users...". The strange thing is that when I se "Use a proxy server for you LAN" (on IE, Tools, Internet Options, Connections, LAN settings) and the name of the ISA Server, it works fine, no authentication is required. Could anyone Please help? Appreciate, Mark
