How to drop linked Server from SQL Server 2008

Another task I can't seem to remember.

Two useful system stored procedures showing linked servers in SQL 2005/2008


exec sp_helpserver
exec sp_linkedservers

I had trouble removing a linked server because I forgot to remove all of the logins.
(seems like removing a linked server should cascade remove the associated logins)

exec sp_droplinkedsrvlogin 'FUSIONRIS','sa'
exec sp_droplinkedsrvlogin 'FUSIONRIS',NULL
exec sp_dropserver 'FUSIONRIS'
