There are two options possible. One of them is already implemented in my organization:
Background image on login screen
Add important information like password rules on desktop background image.
However, if you do not have a common image for all users, this will not work. Also, if users are allowed to change background, then too, this will not work.
Logon Message
Add a message when user tries to login. This can easily be done by editing group policy. You can find more details here.
Follow these steps to add a logon message:
- Login to the domain controller machine with the administrator account.
- Open
Group Policy Management Editor
