This policy setting enables intranet mapping rules to be applied automatically if the computer belongs to a domain. If you enable this policy setting, automatic detection of the intranet is turned on, and intranet mapping rules are applied automatically if the computer belongs to a domain. If you disable this policy setting, automatic detection of the intranet is turned off, and intranet mapping rules are applied however they are configured. If this policy setting is not configured, the user can choose whether or not to automatically detect the intranet through the intranet settings dialog in Control Panel.

Export Builder
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.
