Windows 10: how to change local administrator password for all computers in domain?

Hello all, I am working in a Windows environment with about 400 users. Some of our laptops have local admin accounts that were created with random passwords and I would like to reset them all to something else without having to manually access each laptop. I know there used to be a way to do this from Group Policy but it has been disabled. Any advice/tips are appreciated! Thanks

:)

 

How to reset Windwos 8 Password?

Change or reset your Windows password - Microsoft Support

• If you've forgotten your Windows password, there are several ways to retrieve or reset it:
  • If your PC is on a domain, your system administrator must reset your password.
  • If you're using a Microsoft account, you can reset your password online. ...
  • If you're using a local account, use your password hint as a reminder.

 

Can't login as local user after adding a computer to a domain


Here are the steps I took. Please tell me if I should have done differently.

1. On the server end add the user and computer to the domain in advance.

2. Fresh install windows 10 and make the first username Admin.

3. Once at desktop rename PC to match PC name on domain i.e. Workstation001.

4. Add computer to mydomain.local and when asked for username and password I entered the credentials for the new user.

5. Restarted the PC and signed into mydomain\newuser without any problems.

However now when I try to access the original local Admin account by typing 'Workstation001\local Admin' as the username and then the password. It keeps saying password invalid.

So I logged back into the domain account and tried resetting the password to Admin and then tried signing in as admin again, still no luck.

Currently there are 2 accounts on the computer one of them is a local/domain account for newuser and the other is a local Admin account which I cannot access.

What kind of glitch is this? Should I have not joined the domain through the original Admin account and instead added a local user to the PC 'newuser' and then sign in as that user locally then add them to the domain through their own local account? I didn't think this was necessary.

 

Can't login as local user after adding a computer to a domain

Your logon username for local is incorrect.

If the username created was "Admin", then the local machine logon is:

Workstation001\Admin (Omit "Local") It already knows you are logging onto the machine from the machine header.
