Policy CSP - ADMX_NCSI
Tip
This CSP contains ADMX-backed policies which require a special SyncML format to enable or disable. You must specify the data type in the SyncML as <Format>chr</Format>. For details, see Understanding ADMX-backed policies.
The payload of the SyncML must be XML-encoded; for this XML encoding, there are a variety of online encoders that you can use. To avoid encoding the payload, you can use CDATA if your MDM supports it. For more information, see CDATA Sections.

./Device/Vendor/MSFT/Policy/Config/ADMX_NCSI/NCSI_DomainLocationDeterminationUrl
This policy setting enables you to specify the HTTPS URL of the corporate website that clients use to determine the current domain location (i.e. whether the computer is inside or outside the corporate network). Reachability of the URL destination indicates that the client location is inside corporate network; otherwise it's outside the network.
Note
This indicates the Network Location Server (NLS) URL and applies exclusively to DirectAccess clients (it does NOT apply for example to VPN clients). For non-DirectAccess scenarios, such as Microsoft Entra-only joined devices, please refer to Policy CSP - NetworkListManager.
