Several users will remotely log into the Server 2012 R2 as themselves (UserA, UserB, etc) but when they click on Start, UserZ's First and Last Name is displayed on the top right corner.
%UserProfile% points to the correct folder (C:\Users\UserA, C:\Users\UserB, etc)
%username% in command prompt displays the correct username (UserA, UserB)
whoami in command prompt results in their login username.
Active Directory First and Last Name is correct.
In the registry I've checked:
Default > Reg_SZ > (no value set)
I've also searched in the registry for
HKU\* (everyone *except* UserZ)
I found the values under registry path
I see User A's name under ADGivenName + ADSurname and also FirstName + LastName. DisplayName is blank.
I changed the values of First Name + Last Name but when I logged out and back in they went back to their original values.
When logged into as User A:
FirstName and LastName are blank. DisplayName is administrator.
Everything past when I ran dcdiag /fix
Any other suggestions on how to fix it?
