my username in will not work on a different computer..we are on a network and i cant use my username on a different network.do u know of a way how to bypass this..my friend usually borrows my username so he can use the internet at his station. this worked before but now he cant use it anymore..he gets a message saying that username was configured..our technicians configured our usernames.do u know how to resolve this?is there a hack that we can do?

i think the password has changing by another person, please ask your LAN administrator
