This policy setting allows you to control which site zones are included in the discovery functionality of the Internet Explorer Site discovery Toolkit(SDTK). When enabled the feature will collect data from sites that are part of the zones configured in the policy. When disabled or not configured all Zones will be included in site discovery. This policy can be used in conjunction with other policies controlling sites included in Site Discovery. To configure zone(s) included in site discovery, a binary number is formed based on the selected zones. The decimal representation of this number is used to represent this number in policy. For example: • 2 - Intranet site zone only Binary Representation - 00010 • 0 - Restricted Sites Zone • 0 - Internet Zone • 0 - Trusted Sites Zone • 1 - Local Intranet Zone • 0 - Local Machine Zone • 6 - Intranet and Trusted site zones only Binary Representation - 00110 • 0 - Restricted Sites Zone • 0 - Internet Zone • 1 - Trusted Sites Zone • 1 - Local Intranet Zone • 0 - Local Machine Zone • 22 - Trusted, Intranet, and Restricted site zones only Binary Representation - 10110 • 1 - Restricted Sites Zone • 0 - Internet Zone • 1 - Trusted Sites Zone • 1 - Local Intranet Zone • 0 - Local Machine Zone

BETAConfigure the state, scope and options, then generate .reg, PowerShell, Intune and SCCM outputs — or add the setting to a multi-setting collection.
These exports write the registry — this is not a managed GPO. ⓘ
Applying both scopes creates an ambiguous configuration (computer takes precedence over user). Only do this intentionally.
