When you click a Microsoft Office 2003 document or a Microsoft Office XP document, a Connect to ServerName dialog box appears.

This issue occurs if the following conditions are true:

•	The Office 2003 document or the Office XP document is stored in a document library.
•	The document library is stored in a Microsoft Office SharePoint Server 2007 site, in a Microsoft Office SharePoint Portal Server 2003 portal site, in a Microsoft Windows SharePoint Services 3.0 site, or in a Microsoft Windows SharePoint Services 2.0 site.
•	The Web servers are part of an intranet or an extranet.

Additionally, you are prompted to enter your user name and your password even though you already entered your user name and your password to access the site.

This issue occurs if the virtual server in Microsoft Internet Information Services (IIS) 6.0 is configured to use Basic authentication. Your user name and your password do not pass seamlessly from Microsoft Internet Explorer to the Office program.

To work around this issue, configure the virtual server in IIS 6.0 to use Integrated Windows authentication instead of Basic authentication. To enable Integrated Windows authentication and to disable Basic authentication for a virtual server in IIS 6.0, use one of the following procedures, as appropriate for your situation.

Note SharePoint Server 2007 and Windows SharePoint Services 3.0 use the term "Web application" instead of "virtual server."
