    As a little bit of background, our Helpdesk already has many self-help articles on our internal intranet site and we want to leverage this content rather than having to maintain and update the same article in multiple locations. I created a KB, used exertnal content and linked it to a Service Offering that is published in the portal. I can go to the portal and see the link for the article, just as I had expected, but clicking on it gets me the following:


    Server Error in '/ContentHost' Application.


    The remote certificate is invalid according to the validation
    procedure.

    Description:
    An unhandled exception occurred during the execution of the current web
    request. Please review the stack trace for more information about the error and
    where it originated in the code.

    I found another post that detailed this fix, which allows you to view a KB from the SSP, but still doesn't solve the next problem I will post about, not being able to display a KB comprised of only External content.

    I used the default location so my web.config file is placed at C:\inetpub\wwwroot\System Center Service Manager Portal\ContentHost\Web.config

    Example:

    Edit from

    <add key="ContentHostAbsoluteUri" value="https://SCSM01:443/ContentHost" />

    To

    <add key="ContentHostAbsoluteUri" value="https://SCSM01.contoso.com:443/ContentHost" />
