I have a small network all running windows 10. When I am on one of the computers I can see the other computer listed under network. If I click on the listed computer's name it asks me for the computers credentials. I know the only user on that computer is Administrator and I assume the password is the same as the password I use to log into the computer when I first turn it on. When I try this it does not let me in. I have tried the computer name for user name I have tried Administrator and still nothing. When I look on the computer I am trying to access under user profiles there is only one profile and it says Administrator. What am I missing? Why can I not access the unit? Thanks in advance for your help.
