My question is about your status in this issue... Do you manage the server? What error messages are you seeing to notify you of the problem? Or...Are you a homeowner with a computer which can't connect? If so, I'll guess you had a static IP address and needed to change it? Yes, No? If it was static, can you change it to automatic detection in the network adapater's properties?
Which operating system are you using?
Tried flushing DNS?
Hope this helps and let us know more.
