The problem was with my firewall and i fixed it but now i have a new problem. now when i try to connect to the host computer, i get a message "Logon failure: The user has not been granted the requested logon type at this computer." and when i try to add a printer, a login screen comes up with the user name FAMILYROOM/guest (which i cant change) and i have to enter a password. i dont know the password and i dont no why it is password protected.
