To change adomain passwordfrom a remote location, the system must communicate with thedomain controller. Since the user is working from home, they need toconnect to the corporate VPNto establish that secure connection. Without it, the password change cannot be authenticated.
Option A:Restarting will not resolve the lack of connection to the domain controller.
Option C:Resetting the password in AD could help, but doesn't let the user reset it themselves.
Option D:The user may already be on Wi-Fi; the issue is with connecting to thecorporate network, not local.
