Hi, it sounds like you've tried much of what I would recommend, but see off there might be additionl things here...
Make a New Location, Using network locations in Mac OS X ...
10.7 & 10.8…
System Preferences>Network, top of window>Locations>Edit Locations, little plus icon, give it a name.
System Preferences>Network, click on the little gear at the bottom next to the + & - icons, (unlock lock first if locked), choose Set Service Order.
The interface that connects to the Internet should be dragged to the top of the list.
Is that Interface dragged to the top of Network>Show:>Network Port Configurations.
If using Wifi/Airport...
Instead of joining your Network from the list, click the WiFi icon at the top, and click join other network. Fill in everything as needed.
For 10.5/10.6/10.7/10.8, System Preferences>Network, unlock the lock if need be, highlight the Interface you use to connect to Internet, click on the advanced button, click on the DNS tab, click on the little plus icon, then add these numbers...
If that doesn't work try changing channels on your Router.

Ok - tried it all.
Still not working on the different users - just the admin controlled user.
the other users on the account seem not able to connect thru to a server to browes even the www.apple.com pages.

Long shot maybe but have you enabled System Preferences>Parental Controls and accidently denied all other users access to the Internet (or on all websites but a few in the list OSX creates by default?)
