cannot extend the virtual server or get to Extend Virtual Server p

[Jesse]

I'm using Win2003 Server SP1 and SQL 2k SP4. I've installed WSS with no
problem. All is fine untill I get to Extend the Virtual Server. I select
Extend or Upgrade the Virtual Server, click the Default Web Site, and instead
of going to the Extend Virtual Server page I get to the Virtual Server
Settings page. I get this error "The virtual server that is referenced here
is not in the config database" when I try to open up any Sharepoint pages.
Any thoughts on what I'm doing wrong?
