Creating a linked server definition
Note: If all sites are on one database server, or if you are not using transactional replication, you can skip this step.
If you plan to perform transactional replication between sites on this database server and other sites that are not on this database server, create a linked server definition in the SQL server master database of both the current site and the To site.
In the SQL Server Management Console, expand the tree and open the Server Objects folder for the current site database server. Right-click on the Linked Servers node and select the server for the To site.
