SQL 2005 - Rename a Named Instance

Hi all,

Ok, first I am new to this so please be gentle. 

1.  I created a named instance on a existing SQL 2000 server for a installation of SQL 2005.
2.  After I named it, I decided that the name needed to be different (GOODNAME vs. BADNAME).
3.  How do I rename a named instance (NOT default instance) of a SQL Server 2005 install?  I have completed the steps shown in this article.

But, it still shows as the name I do not want in the SQL Management Studio.   If I run the "PRINT @@servername", it does display the correct name (the one I changed it too).  Yes, I even tried rebooting.

I want to be able to connect via the Management Studio to the same name that I named it to using the steps in the article above. 

Do I have to uninstall it and reinstall or is there something else I need to do? 

More Details...
1. Server Instance name (BADNAME)
2. Ran commands to rename to (GOODNAME)
3. Checked using @@servername and it shows ... GOODNAME.
4. In Management Studio, it still shows (ever after reboots, etc.) ... BADNAME.
5. How do I get it to show ... GOODNAME in Management Studio? 

As always, any help/guidance is appreciated!

Regards,

Steve
