Help! Windows live sign on,

[chanta45]

Hey guys, down visiting my woman and we are trying to play dawn of war together on the PC. We share one router and I can sign in just fine onto warhammer but when she tries too it says her windows live can't sign on due to network problems.

Is this something to do with a conflict of IP adresses? I mean the most i've done in terms of routers is follow a guide to open some ports but thats it.

Would really appreciate some help
