Won't Redirect to login page on public wireless networks (e.g. coffee shops)

Windows XP Home Ed. V5.1
Firefox and IE

I normally can get on wireless networks no problem. However, if the
network requires I go to a certain page first (for example, to accept
the conditions of their network) then I can't get on. Instead, my
browser just tells me that my homepage cannot be found. I *think* the
problem is that my browser won't allow me to be redirected to their
network's login site, and just tries to go to my homepage. Then the
network won't let me go to my homepage (yahoo) because I haven't gone
through their login page yet.

I've tired without my firewall, I've tried both my browsers, I've tried
without any anti-virus software, etc. What could it be?
