Intranet Zone

Intranet Zone

The Site may be added to the Intranet Zone (in Internet Options) by specifying a setting with the key Policies.TrustedSites and an array of URLs. These URLs are parsed by RealmJoin and written to a registry key called ZoneMap.
One might specify the following JSON array:
["file://", ""]
which will result in the following rules:


  • Windows will interpret a naked domain like file:// as file://*
  • RealmJoin does not allow for wildcard protocols. You must specify all protocols explicitly.
  • RealmJoin will manage all protocols for a configured domain and remove any user-added protocols.
  • RealmJoin will not manage other domains which are not configured in this setting.


Many customers have extensive Intranet Zone list. Clean it up! Investigate whether a site works without adding it to the Intranet Zone.
  • Add a site using https protocol if it uses Integrated Windows Authentication or other legacy features like ActiveX.
  • Add a server using file protocol if it is accessed using SMB.
