Linked server in sql server 2008

When you are setting up a linked server, register the connection information and data source information with SQL Server. After registered, that data source can be referred to with a single logical name.
You can use stored procedures and catalog views to manage linked server definitions:
• Create a linked server definition by running sp_addlinkedserver.
• View information about the linked servers defined in a specific instance of SQL Server by running a query against the sys.servers system catalog views.
• Delete a linked server definition by running sp_dropserver. You can also use this stored procedure to remove a remote server.
You can also define linked servers by using SQL Server Management Studio. In the Object Explorer, right-click Server Objects, select New, and select Linked Server. You can delete a linked server definition by right-clicking the linked server name and selecting Delete.
When you execute a distributed query against a linked server, include a fully qualified, four-part table name for each data source to query. This four-part name should be in the form linked_server_name.catalog.schema.object_name. For more information, see Distributed Queries.

Step-by-step procedure available in below article.
