The simplest way is to run an asp page that will fetch the report and display it.
You can do it with the following example code, just replace the URL with your own reporting url, login and password:
set objhttp = server.createobject("microsoft.xmlhttp")
url = "http://sqlreport01.mysite4now.com/ReportServer/webho_demo/Report1&rs:Command=Render&rs:Format=HTML4.0&rc:Toolbar=True&rc:JavaScript=False&rc:LinkTarget=_top&rc:Area=Report"
objhttp.open "get", url, false, "login", "password"
objhttp.send
response.write objhttp.responsetext
