Within a Server 2016 AD network what program, utility, or command can I run to view which Active Directory users are logged onto which computers?
If this can't be done with the native Server 2016 software utilities, power shell or command line commands, what kind of software can be purchased to do this?
If you setup login/logout scripts that registers each user, date time, computer, logon server against which it authenticated, console, logout time...
Apply to the user OU, no matter what system the user logs into, you'll have the information to query as you see fit.
Which users are loggin into a system, which system a user used, duration of time
