Getting rid of an old FM server?

[diamondgirl]

I had to reinstall Filemaker server 9.0 when I forgot the username/password for the admin console. I also had to reinstall OSX Tiger server as well--I really messed it up. Now, everything is working great and has been for the past few months. However, whenever I need to adjust the OS X server admin settings (I added a new printer yesterday) I get the OLD filemaker database IP address from last year AND the one we're using now under local hosts! Better yet, this old "local host" ip address comes and goes, now it's gone. It's phantom presence caused startup issues--what a mess! Remember, my original problem is that I lost the username and password.

How do I get rid of this old Local Host?
