Symptoms

When you use Microsoft Office FrontPage 2003 to insert a Data View Web Part while you are authoring against a Microsoft Windows SharePoint Services Web site, you may receive an error message that is similar to one of the following:
The Data Source does not contain valid XML data.

The Web server cannot connect to the specified data source because the query may contain errors, the data source may be unavailable or configured improperly, or your Web site is behind a proxy server or firewall.

If your Web site is behind a proxy server or firewall, verify that your server administrator has configured the Data Retrieval Services HTTP proxy server setting for Microsoft Windows SharePoint Services.
An error occurred while processing the data for this request. Contact the server administrator for more information.

Cause

This behavior may occur if you try to connect to a data source outside your firewall. If you do not specify the proxy server, the default proxy that is provided by Microsoft .NET Framework is used.

<system.net>

    <defaultProxy>

      <proxy proxyaddress="Insert_Proxy_Address_Here" bypassonlocal="true" />

    </defaultProxy>

  </system.net>
     where Insert_Proxy_Address_Here is the proxy address that you want to use.
