I have installed Windows 7 operating system on my machine and I am facing some strange issue while accessing an internet from this windows machine. Actually when I try to connect with an internet then I am prompted by Windows Security Network Authentication window which asks for a username and password. Now I don't have any idea that why it needs these username and password for getting connected with an internet connection. Please help me, I want to connect this machine with the network as soon as possible.
