404 Error after Fresh Install on IIS 6.0

Jun 29, 2010 at 11:55 PM

I've just done a fresh install on an IIS 6.0 webserver with ASP.Net 4 platform.  I can browse an index.htm file, but when I try to browse the Default.aspx (or anyother .aspx) file, I get a 404 page not found error.  Any suggestions?
