Delete a SSP (Shared Service Provider) in a farm

You can only delete a SSP (Shared Service Provider) when you have installed SharePoint as a Farm. There are two ways to delete a SSP:
1) Via a browser: http:///_admin/deletessp.aspx?ssiId=
2) Via Command line: stsadm –o deletessp –title

Also keep in mind when you use number 2 it will not remove the two databases created for the SSP and SSP Search. This means you have to go into SQL Server to remove them your self.
