Question : when user opens web browers it redirects to a certain page first

ive seen this done a million times over wifi networks and a few times over wired connections.

lets say you got to a strabucks or hotel.

when you connected to there wifi it ask you ether to pay or accept the conditions of the network?

ive seen a few programs that will do it for wifi but how would to do that for a wired connection?

example.

if user opens ie, there home page is set to google.com but we want it to go to msn.com globally, on every computer on that network

is this possible, is it software or hardware?

thanks all
