Hi ,good day
see if u project contain a mixture of asp & asp.net file then on debugging locally from the start debug option in VS2005 then it will create problem , on output it will show(for asp pages) this type of file is not supported like that,in that case you have to be on "hosting" with any web server(hosting area,that support both the file type asp & asp.net etc),in that case u can easily type u domain name & can check(debug) u changing(coding) becuse asp & asp.net have totally different file patern,so hope u can solve u's problem.
Bye
