GUI Method:
- On a domain controller or domain computer with RSAT tools installed, open Active Directory Users and Computers.
- Locate the user's account.
- Right-click the account and select 'Disable Account'.
- Reset password if requested (Right-click > Reset password)
Command line method (faster):
- In an elevated command prompt on a domain controller (including Screenconnect command line) type the following, replacing `(username)` with the actual login name of the user, then hit Enter.
`net user (username) /active:no`
- Reset password if requested (`net user (username) (newPassword)`)
