How to make Nginx forget a hostname?

[jbjares]

Hi Nginx forums team,
I'm with a issue related a removed configuration file for a specific
hostname. So, I need to associate the hostname with a new ip address from
other vm, but it's not possible because, this hostname always are resolved
by nginx. I am using ubuntu server lucid 64; I removed the sites-available
and sites-enabled config files for this virtual host, as well as reloaded
the nginx service. Anybody knows, if I'm forgetting anything, or if this is
a common issue?

Best Regards.
