I shut my computer down the other night. When I got up I turn it back on and it came up to the username screen. I do not have a password on my account so I clicked the icon it open the password box so I click on the green arrow and I got this response The system cannot log you on now because the domain DARNELL-BF298FA is not available. I tired the other username and got the same qanswer. I went to safe mode and tired administrator which I iknow has not password and still gtot the same response. I can not get by the username screen. This computer is not connected to a network. I use cable for my internet. I need to know how to get by the username screen and to change the domain.
