Moving Request Tracker from default URL to new URL on Windows 2000

Anybody have experience with moving a default install of Windows version of
Request Tracker from default URL to a new URL (IP)?

I finally figured that hardcoding URL in
C:\Program Files\OurInternet\Request Tracker\winrt\conf\RT_Config.pm

will work but that is not a good solution.
Do I need to add a Virtual host?

Thanks for any insight.

Oh this is the default install so it is using Apache.
