can't access internet (IE), MSN is working

hi all.

One of the computers in the office can't access the internet (can't surf with IE) but it will log on to MSN with no problem.

I've seen this before, but I forgot how it was fixed, or what the problem was.

ANy ideas?
Thanks

go to:
http://www.mozilla.org and download FireFox on another computer then install it on that one
(joking but not joking)

anyway, try going Tools>Internet Options... then:
click Connections then click "Setup..." button set the settings as for that computer.

If that doesnt work, make sure there is nothing checked or filled in on the "LAN Settings"

and if that doesnt work, well reply and we will see what else all of us can come up with.
