How to restrict domain users from changing password using group policy

There's a way using AD. Just select a use and go to the Account Tab, and select "Password never Expires" and "User can not change the password".

If you are interested in doing this to many users in an OU, just highlight all users > Properties > Account Tab > Under Account Options enable "Password never Expires" and "User can not change the password".

Here is how to set the password never expires portion.
Also you can select all your users  at once in ADUC then right click and choose passwords never expire.
Going forward when you add new users you will need to check mark that field when creating the user

I tried it by selecting all users and then changing the settings as told by "ryansoto:" and "pzozulka:" but some how it is getting deselected for few users, that's why i want to do it using group policy.

Is there any option in Group Policy to do this ?

User Configuration>Administrative Templates>System>Ctrl+Alt+Del Options>Remove Change Password>Enabled

However, this only prevents them from changing the password from Ctrl+Alt+Del. There are other ways to change passwords, which is why instead of hiding a button from them, it would be best to all together remove the ability to change a password within AD itself the way I specified earlier.

Some users are getting deselected, because they were once selected. Make sure that you go through all the user accounts and make sure everyone is on the same page (deselected). Then follow the instructions in my 1st post.
