IIS 5.1 on XP Pro with ASP 2.0.50215

I fully admit to being a true nubie, so be kind.

I've somehow screwed up my IIS 5.1 after installing ASP 2.0.50215 and
testing some basic ASP pages. I receive a Forbidden message which
appears at face value to be a permission issue but I'm running MS
Visual Web 2005 with administrative privledges.

I don't know this is the issue but I did note that the ASP settings
were calling for the web.config file found at:

C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\config\web.config.

I'm using ASP 2.0.50215 and in the similar directory:

C:\WINDOWS\Microsoft.NET\Framework\v2.0.50215\CONFIG

there is no file called web.config. there is web.config.comments and
we.config.default but no we.confg.

Thanks for any direction
