Hi
First you have to make sure that the computers have a valid connection to
the Router.
Try to access the Router's menu from each computer through the browser.
You can check each computer's network configuration with the help of this
page, http://www.ezlan.net/debug.html
If the network connection is valid then this might help,

Hi I have a couple of machines that when I try to access an nww page, gets
the site couldn't be found message from the browser - which is IE7 & this
also happens in the latest version of Firefox. Anyone got any ideas? It's
not DNS. Has to be something local to the PC because the same user profile
on a different machine has no problems.
Many thanks
