Hi, I have installed DNN and it's working fine. I am planning to use DNN as a corporate portal for my organization.
Hence, I have to incorporate a lot of e-forms developed into DNN. I think the only way to do that is by creating iframe and call my own developed .net application in it.
Therefore, after creating an iframe, I use to call my application with an URL address like below:
| |
|
The URL of the document to show in the iframe
|
|
The URL:
http://portal.company.com/Portaldnn/asps_new/people/xxx.aspx
This way was working fine earlier, but after I change the authentication method of DNN to be windows authentication, I started getting the following error message. Could someone help me PLEASEEEEE!
Server Error in '/PortalDnn' Application.
