Create a Linked Server with master.dbo.sp_addlinkedserver.

ALTER ANY LINKED SERVER permissions are required

 Drop a Linked Server with master.dbo.sp_dropserver.
ALTER ANY LINKED SERVER permissions are required

Create the mapping of a local login with a remote server with master.dbo.sp_addlinkedsrvlogin
