This policy setting prevents computers from connecting to both a domain based network and a non-domain based network at the same time.
- If this policy setting is enabled, the computer responds to automatic and manual network connection attempts based on the following circumstances:
Automatic connection attempts
- When the computer is already connected to a domain based network, all automatic connection attempts to non-domain networks are blocked.
- When the computer is already connected to a non-domain based network, automatic connection attempts to domain based networks are blocked.
Manual connection attempts
- When the computer is already connected to either a non-domain based network or a domain based network over media other than Ethernet, and a user attempts to create a manual connection to an additional network in violation of this policy setting, the existing network connection is disconnected and the manual connection is allowed.
- When the computer is already connected to either a non-domain based network or a domain based network over Ethernet, and a user attempts to create a manual connection to an additional network in violation of this policy setting, the existing Ethernet connection is maintained and the manual connection attempt is blocked.
- If this policy setting isn't configured or is disabled, computers are allowed to connect simultaneously to both domain and non-domain networks.
