403 error on accessing new 1.1 site

[John A Grandy]

I created a new ASP.NET 1.1 website on Windows Server 2003.

This server already had 3 ASP.NET 2.0 websites -- all under the same app
pool.

I created another app pool for the 1.1 website. I set the port to 83.

Settings other than the ASP.NET version were left at their default values.

When I access the site via my dev box over the intranet http://server1:83 I
receive a 403 error.

Turning anonymous access off does not solve the problem.

I have not encountered this 403 before -- I am wondering if the mixture of
1.1 and 2.0 sites on different ports could be the cause.
