Select the source of Group IDs

Set this policy to restrict peer selection to a specific source.

Options available are:

1 = AD Site.

2 = Authenticated domain SID.

3 = DHCP Option ID.

4 = DNS Suffix.

5 = AAD Tenant ID.

When set, the Group ID will be assigned automatically from the selected source. If you set this policy, the GroupID policy will be ignored.

The options set in this policy only apply to Group (2) download mode. If Group (2) isn't set as Download mode, this policy will be ignored.

For option 3 - DHCP Option ID, the client will query DHCP Option ID 234 and use the returned GUID value as the Group ID.

Supported on: At least Windows 10 Server, Windows 10 or Windows 10 RT
