Windows Local Account “Access Denied” errors: PowerShell fix script for Windows 10 or Windows Server 2016

Troubleshooting


Problem

Beginning with Windows 10 version 1607 (Creator’s Update) and Windows Server 2016, the default GPO security descriptor denies users remote access to Security Account Manager (SAM) with non-domain credentials, and therefore prevents remote heartbeat and password changes made by otherwise-authenticated local user accounts. Affected Windows Local Account secrets would return “Access Denied” on a heartbeat or remote password change.
 
The script addresses these "Access Denied" errors by modifying the default local group policy Remote SAM Access security descriptor to allow all local users on a specified machine remote SAM access after authentication. This script requires elevated PowerShell permissions.
