Hi,

How do i crack the above username/password ?




I would like the laptop which i brought from home to office,
to access the internet. So far i can only access the intranet.


Is there a way to change intranet IP ?


i been using my work PC to check certain stuff on the intranet server.
found the admin login and realized they keep a log of who is accessing the login.
My intranet Ip show up there.


Thank you
