When tried to setup OOBT Sharepoint RSS Viewer Web Part I got the following error. RSS Viewer webpart will now only work with Authenticated feeds (default for MOSS) when the MOSS server is setup with Kerberos authentication.
"An unexpected error occured processing your request. Check the logs for details and correct the problem."
I located and opened the web.config of the SharePoint site I wanted to put the RSS Reader webpart into, I added this at the very end of the file ( inside the last tag ()):
Then I got this error below ,
"The requested feed url does not exist."
I then added the port number for the proxy server,
After adding the port I got a new error shown below,
"ProtocolError occured trying to complete the request. The server returned a status code of : ProxyAuthenticationRequired and the status description is : "Proxy Authentication Required ( The ISA Server requires authorization to fulfill the request. Access to the Web Proxy service is denied. )" "
Added rule in the proxy to allow anonymous outbound traffic from the SharePoint web server. After adding the rule I got the error below.
ProtocolError occured trying to complete the request. The server returned a status code of : Forbidden and the status description is : "Forbidden"
In the rule alow xml file in http protocol and it worked.
Enhanced RSS Viewer Web Part (It can connect to rss that requires authentication as well)
