"Setup the Server
A web-based, "wizard" driven setup and configuration tool is built into Openfire. Simply launch Openfire (platform-specific instructions below) and use a web browser to connect to the admin console. The default port for the web-based admin console is 9090. If you are on the same machine as Openfire, the following URL will usually work: http://127.0.0.1:9090."
Some may think that the initial setup can be done only on localhost. Should be a comment, that setup and administration can be done remotely also.
added a comment: " Initial setup and administration can also be done
from a remote computer using LAN IP address instead or hostname if it is resolvable by the remote computer."
Attaching the changed html
Added "Windows Server 2003 administrators should add http://127.0.0.1 address to Internet Explorer's Trusted Sites list, if
Enchanced Security configuration is enabled in Internet Explorer. Otherwise they will get a blank screen." to Setup the Server chapter.
