Description
To minimize potential points of attack, local users, other than built-in accounts such as Administrator and Guest accounts, should not exist on a workstation in a domain. Users should always log onto workstations in a domain domain with their domain accounts. This does not apply to laptop PCs which are designed to function both on the domain and off the domain.
