Page Viewer Web Part RRS feed

  • Question

  • Running WSS 3.0. I have setup a Page Viewer Web Part that displays a folder from a shared folder. It works internally. Externally, we get "unable to display web page". How can I troubleshoot this?

    Thanks, Chris

  • Hi Chris,

    Could you please kindly check if it is external URL used by the Page Viewer Web Part in External site?

  • Thank you for the reply. The Page Viewer URL is pointed towards an internal server - \\InternalServerName\Shared

    Thanks, Chris

  • Hi Chris,

    Can you access this location by clicking the test link in Edit Web Part pane? Will it ask for validation? After type the user certificate, can you access it now?

    I would like suggest you to use a Shared location instead.

    Thanks & Regards,

  • If I click on the 'Test Link', nothing happens.

    What do you mean by Shared Location instead?

    Thanks, Chris

  • Hi Chris,

    I believe that what you're experiencing is expected behavior.  Check this post out:


    It looks like the web part basically doesn't know how to pass the current users credentials to the internal location.  I would bet that if the external user accessed the share first, then accessed the page viewer web part, that it would work.  It's as if the web part doesn't know who the user is.  In the thread above, the recommendation is to create a custom web part, but depending on your requirements (and programming skills), have you considered any alternatives to exposing this content?

    This post has a similar theme, but I would think that Network Monitor would log the attempt at the port level on SharePoint:


    Are the external users authenticated to the domain where the share is located?  How about this for a solution:


    Hopefully some part of this has been useful to you.  My apologies that the web part doesn't seem to be capable of what you need it to do out of the box.

    Best Regards,

  • This is pretty much going to be a DNS issue.  As your \\InternalServerName is not known to the outside world, an external client will never know how to find the server or the share.

    When you load your page externally, all the elements are rendered by your browser and the name resolution is handled by whichever DNS provider you're currently using.  Your browser will see the page viewer web part as an iFrame and try to resolve the name InternalServerName to provide the content.  It wont even get to the point of passing credentials.

  • I did find a solution to this issue. Since the Page Viewer web part will not display the internal files, while accessing from outside the comapny, i found a product that does -
