Here's the setup: ISA running on "flagship" with a webserver, "web" and a workstation, "digistudio" behind the firewall. Here's the problem: Against popular suggestions, I store all web content in the inetpub/wwwroot folder on the D:\ drive of the web server. This mirrors the setup we use at work so I can develop properly. Anyway, I had the default web site configured to the folder youthonestop_org in that folder on the D:\ drive. Well, I am now learning C# and .Net and need to have access to other websites. So, the default website's local folder is now C:\inetpub\wwwroot\. But, from a browser, if I type in Localhost or 127.0.0.1, I get a "File Not Found" error but if I type in the URL, http:\\www.YouthOneStop.org, I get to the default.htm page on the C:\ drive. Can anyone tell me what is going on and if this is an ISA or ISS problem??? Thanks, Jon
