I'm running SQL Server 2005 enterprise edition on a 2 node active-active cluster windows 2003 server. I go to add/remove programs, click on SQL Server and then the link for "to install a new component, click here". It then says enter the location. Where do I go to find SSIS add-on from here? 

Is SQL Server Integration Services offered on the SQL Server Installation dvd or is this something I need to download?

thanks in advance
