How to link another server in SQL Server 2005?

or
Basically – all I needed to do what set up a linked server by using the following system stored procedures:
sp_addlinkedserver '<Server Alias>', '', 'SQLNCLI', NULL, NULL, 'SERVER=<IP>', NULL
sp_addlinkedsrvlogin '<Server Alias>', 'false', NULL, '<username>', '<password>'
To remove the linked server once done then just call
sp_dropserver '<Server Alias>', 'droplogins';
example : u have another data base is running in different server(System) u need some tables,columns from that Server to write some query in that query u need that columns so u have to link with that server using above scenario then u can use those columns in your query.
for instance set up a linked server called myRemoteServer, then I would be able to access a table in the remote database using:
myRemoteServer.<DatabaseName>.dbo.<TableName>
It makes it relative much easier to map data between sources compared to having to backup/restore the remote source database to the target server.
