Also, have you enabled ASP.NET 3.5 on the box?

How do you enable 3.5? I found this article:

http://community.aspnix.com/showthread.php/2627-How-To-Enable-AJAX-.NET-Framework-3.5-on-IIS7-Server

but it looks like your default webconfig file has all the entries

You need to go to server manager and add roles.

See: http://forums.asp.net/p/1483086/3750984.aspx

I went into Server Manager->Roles->Web Server (IIS). In the section 'Role Services' everything had a status of 'Installed'. Also, the 'Add Role Services' link on the right side of this panel is disabled (it cannot be clicked) I'm guessing because all roles are installed. Any other ideas?

As a side note I was able to get rid of the original error after I made a change to the webconfig file. I added this entry:

<add name="PageHandlerFactory-Integrated" path="*.aspx" verb="GET,HEAD,POST,DEBUG" type="System.Web.UI.PageHandlerFactory" preCondition="integratedMode" />

The Gemini application pool is running in integrated mode but I noticed the only *.aspx handler had a precondition for running in classic mode. After I added that entry to the webconfig file I now get a generic error page when I try browsing to this site. I found the following in the event viewer:

By the way, thanks for the quick feedback.

Please set the customErrors tag to Off in the web.config file and try again,
