Hi I wonder if anyone can help with a problem I'm trying to help a colleague with. Basically when he's behind a router he can browse the internet fine, log in to OWA OK using IE 7 or Firefox, but can't reply or forward messages. When he clicks 'send' it hangs and sits there. This is either wirelessly or direct to the ethernet port of the router. (We've tried two different 2wire 1800 routers) When I reconnect his ADSL USB modem it works absolutely fine. This happens with two different XP laptops (fully patched and up to date, spyware free). Also when I take either of the routers back to my house they work fine (even with the same laptops) Can anyone suggest anything else to try? Cheers Alister
