You can connect the computer running Project Server 2003 to
a Windows SharePoint Services–compatible portal site that is
running Microsoft SharePoint Portal Server. This feature takes
advantage of the integration between Windows SharePoint Services
and SharePoint Portal Server. After the connection to SharePoint
Portal Server is specified and saved, each Windows SharePoint
Services site collection that Project Server 2003 creates is
automatically aware of the server running SharePoint Portal Server.
Users can search documents, issues, and risks; add sites in
SharePoint Portal Server that can be used to personalize data; or
promote a document in a document library onto your
organization's portal site.
