After rebooting, Windows 10 is presenting the user with the wrong login account. It looks like her domain account, has the right name displayed, but no domain, just her login name and password box. When she completes the login, she gets in, but has no access to network devices. It looks like Windows is using her email address rather than her domain account. I have logged in with a local account and deleted her domain account, rebooted, and added her domain account back in and the behavior was the same. It's like her email account and the domain account are intertwined. The machine is a member of our domain and her domain account is in the administrator's group. If "Other User" is selected the user name and password are entered, the domain name is also displayed, and the login is successful and she has access to network resources, specifically, mapped network drives. With the other account, the mapped network drives have that big old red x. So here is the issue. How do I configure Windows 10 to display the domain account as the default, and not this email account?
