Resetting a Computer Account

Community Resources PowerShell Library

Like a user account, a computer account interacts with Active Directory using a password. But for computer accounts, a password change is initiated every 30 days by default and the password is exempted from the domain’s password policy. Password changes are driven by the client (computer), not AD.

Computer credentials are usually unknown to the user because they are randomly set by the computer. However, you can set your own password using PowerShell.

Resetting a Computer Password

$pc = read-host –Prompt "Input computer name to reset" # Specify the computer name
$pw = read-host –Prompt "Input random characters for temp password" –AsSecureString # Specify the password
Get-ADComputer $pc | Set-ADAccountPassword –NewPassword:$pw -Reset:$true

How It Works

  1. The script prompts you to enter the computer name
  2. It asks for a temporary password
  3. It retrieves the computer object and resets its password

Important Notes

  • Computer password changes are typically automatic and handled by the system
  • Manual password resets are usually only needed for troubleshooting
  • The computer will update its password again within the standard rotation period
