Thanks Tim Sitt.
However, according to my coll CMD. She only saw the top (your pink box) only. The blue box does not exit at all.
In device manager, Network Adapter did shown up. But there's just no IP found at all.
Contacted ISP as well and assured that the net is running well.
This is something she found:
There must be a problem with the driver for the Local Area Connections Adapter.
Windows couldn't automatically bind the IP protocol stack to the network adapter.
Will this help by resetting? http://support.microsoft.com/default.aspx/kb/299357
