Chaning an Instance name

Hi
I have a quick question about renaming an instance.
I used sp_dropserver and dropped the instance name
I used sp_addserver '<servername>, 'local' and changed the local instance
name.
After stopping and restarting the instance, i was able to connect to the new
instance name.
But i can still connect using the old instance name also.
I want to drop the old instance name completely.
How do i do that?
