Information

A computer is considered online if it is connected to it's assigned management point. To indicate that the computer is online, the client sends ping-like messages to the management point. If the management point doesn't receive a message after 5 minutes, the client is considered offline.

Resolution:

Make sure SCCM server has TCP port 10123 allowed on incoming.

To check if client status will display as "Online" you may set Heartbeat discovery and Client status message to 1 so it will be checked every day.
