<p>I am attempting to deploy an ASP.NET 2.0 Web service application on an IIS server that currently serves a large .NET 1.0 web application. </p>

<p>I have set up an appropriate virtual directory and have set the ASP.NET version for the virtual directory to 2.0, when I attempt to browse the site in a web-browser, I am prompted for a password. If I set the ASP.NET version down to 1.0, I am not prompted for a password, but obviously receive a full application error.</p>

<p>How can I configure IIS so that I can have the .NET 2.0 version selected without requiring the password prompt?</p>

<p>I have anonymous access enabled and have the "Authenticated Access" set to integrated windows authentication"</p>

<p>Any help or suggestions is appreciated...</p>

<p>Thanks.</p>

First of all, be sure that you are running two application pools, one for any .Net 1.1 web apps, and another for any .Net 2.0 web apps.
