Turn on automatic detection of intranet
Supported on At least Internet Explorer 7.0
What it does
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.

These deployment candidates come from the ADMX template; they are separate from the native CSP mapping above.
- The OMA-URI is an inferred ADMX-backed Policy CSP candidate derived from the source ADMX file name and policy name.
- Some Microsoft policies use built-in Policy CSP pages whose area names don't match the ADMX file name, so verify the candidate against Microsoft Learn before deployment.
