RealmJoin Client is an optional component that you can use alongside RealmJoin Portal on Windows 10/11 clients. It enables additional scenarios, like
RealmJoin uses the user identity and checks with it at a Cloud-Service for an Extended Policy and optionally for a Secondary Identity, then the RealmJoin Security Assessment checks if the system is qualified (Encryption, Patch Level, Firewall, Anti-Virus, etc. - optionally, an Intune-Health-Check may be sufficient). If the user's device is eligible software- and configuration-Policy will be applied (Mandatory Applications, etc.).
RealmJoin is responsible for two different processes running on the device:
- The realmjoin.exe process is started up automatically on Logon. The process is always running and sends upstream data every 15 minutes.
- The realmjoinservice.exe is called when a package requires the SYSTEM mode to be processed. It is not running by default.
