A website that works fine on PC's and Apples does not display/open some ASP.net webpages on the iPad.

The webpages are unique from those that iPad does open in that they are all dynamically created reports i.e. all of the controls are created dynamically as needed to accommodate the data.

Used the iTeleport application and view the web pages rendered on some other computer using VNC connection. That way you can even view flash enabled web sites on the iPad if you need to.

iTeleport has a delay of about one second over wifi and several seconds over 3G.
iTeleport got its start as jaadu VNC.

Do a Google search for "best VNC iPad" for more information.
