How to remove network adapters?

Hi,
I have been using article 825826 How to troubleshoot
missing network connections icons in Windows Server 2003
and Windows XP. I have windows XP Home. I completed step
11 and there seem to be no hidden or ghosted network
adapters. Completed step 12. I have done this a few times
and now my Local area connection is numbered 5. There
seem to be another one created every time step 12 is
completed. How do I remove the network adapters so I only
have one? In network connections there is only one
showing but it is number 5.
Thank you!
Jerry
