Thanks for posting!
To find the IP address on OS X 10.6.6, click the Apple icon in the upper left hand corner, select System Preferences and then select Network. In there, select the protocol you're connected to (if you have a wired connection, it will be Ethernet, a wifi connection would be Airport) and it should display your IP address.
Also, assuming you're on the server machine itself, you can enter http://localhost:16000 in your web browser and it should bring up the Admin Console Start Page.
thanks i found it and it does bring up the console
