Hi I'm new here so I don't know how things work here but I had a question that maybe you can answer.

My friend had a laptop connected to the internet through DSL (I'm guessing through a router). Everything worked fine and she could access hotmail and yahoo with ease. She got a new computer and her sister installed the DSL on that computer which was connected through a router. Now that both the laptop and the computer are connected to the internet, neither of them can access hotmail or yahoo. They can access all other sites well. I've told her to try different browsers (IE and Mozilla Firefox) but neither of them can access hotmail or yahoo. We've also tried deleting cookies and temp files for IE but it doesn't work.

I'm not too technical when it comes to internet connections so if you can help me please try to tell me in the simplest terms so I can understand. I hope you can help me, thank you.
