You can add an existing document library (Web Storage System-based) on the document library server to the configuration database. You would do this if, for example, you had an unrecoverable error on the configuration database or you created a configuration database and you need to add an entry for the document library.

You can optionally associate this document library with a portal site. If you associate the document library with a portal site, users can search the document library and personalize alerts for the document library. A link to the Document Library area appears on the home page of the portal site. This area enables users to browse folders and to manage documents in the document library.

Connect a document library to the configuration database

1. On the SharePoint Portal Server Central Administration for server_name page, in the Component Configuration section, click Configure document libraries (Web Storage System-based).
2. On the List and Manage Document Libraries page, click Connect.
3. On the Connect Document Library to the Configuration Database page, in the Document Library section, do the following:
   1. In the Document library friendly name box, type a friendly (display) name for the document library.
   2. In the Document library name box, type the document library name section from the URL for the document library. For example, for a document library with a URL of http://server_name/document_library_name, you would type document_library_name.
4. If you want to associate a document library with a portal site, in the Associated Portal Site section, in the Portal site list, select a portal site to associate with the document library.
5. Click OK.
