Hope someone can help with this one (3months into learning SharePoint)..I recently re-designed our company's intranet on WSS 3.0. On several pages of the new intranet, I used a Page Viewer web part to point to existing applications that was used before the move to SharePoint. They all work ok except in one of the application, though its visible in SharePointl, when a button is clicked within the app, it should point to another page within the app, but the error given is shown as:The following file(s) have been blocked by the administrator: /reportfolder/IT/ITReports.aspNow, WSS 3.0 and the old intranet are both running from the same windows 2003 serverbeen searching online, no joy i.e. http://support.microsoft.com/kb/828810, applies to WSS2.0 and not WSS3.0i have tried excluding .asp extension from the blocked list in central admin > Operations > Blocked File types, i just get http 404 not found.seems wss isapi filter is intercepting calls to the page.when i run the app as a stand-alone outside SharePoint, i get the same errorhelp...
