Active Directory Force All Users to Change Passwords on Next Login

First, this is a Bad Idea(tm). Lots of service accounts may not want to change their accounts and you'll break applications that rely on them. The Administrator (500) account will also have to be reset.
Second, this command should only be used when you feel like a scorched earth method is best. It will piss off everyone in the enterprise.The PS is two components, joined by a pipe.
get-aduser -filter * | set-aduser -ChangePasswordAtNextLogon $trueref: https://technet.microsoft.com/en-us/library/ee617195.aspx & https://technet.microsoft.com/en-us/library/dd391883(v=ws.10).aspx
Good luck. I'm not executing that command to verify that it works, but it should. Woe betide the admin that does this in production.
If you adjust the filter, you can ignore Service accounts and such.
-
If your service accounts are in a specific OU (ours are) then you can also just change the scope to the user's OU.

@DustinB3403 why are you injecting a new password when all that was asked was to force the must change at next login Boolean.
-
@JaredBusch Just being lazy and not modifying the powershell that was easily found online.

Plus in a scorched earth approach, is it wise to trust any existing user password? I'd go the entire thing, and make everyone change their password now.
Rather than at next login.

But if they are already logged in, it will not make them change immediately anyway when you change the password.

But it would stop the use of any existing domain password. If a password was compromised it's better to kill it now, and deal with the fall out later.
-
Rather than having to wait for each user to choose when to log out and back in.

How? because any account already authenticated will not lose access to anything immediately. A new authentication will be required. A new authentication will also require a new password.

You aren't reading what I'm saying.

@DustinB3403 and the biggest issues is that a user cannot change a password without knowing the existing password.
By spinning the existing passwords, you make the entire process more difficult.

That is with the expectation that you're allowing the user to willfully change the password, I'm saying change the password for the user, and allow them to change it afterwards them selves.
Not to ctrl alt delete change password / per user.

I did and changing a password does not stop the use of an already authenticated existing password.
Changing the password only means any new log in attempt will fail.
But resetting the force change on next log in will also cause a new log in to not work until the password is changed.

And a compromised password would allow an attacker to possibly change the password before the user gets to.

And this will be known when the user cannot log in themselves because they will not know the new login and their computer's kerberos will not be valid.

Yeah... but the door is still open.
So why go with this approach? Why not force a random password, provide that to the users, reboot their equipment and go from there?

@DustinB3403 you are chasing ghosts and complicating a basic process for no real benefit.
-
Don't allow the users to choose when.
That's insanity, cause they may never log out.

You're leaving the house unlocked and money on the living room floor.

Who said anything about allowing the users to choose? This is setting the framework technically.
This has nothing to do with the reboot cycle.
That should be handled separately in a scenario like this.
