Some clients are shown as black cross mark icon in console

Hi,

1,The clients with black cross mark icon mean that they are inactive. Client status of inactive are indicative of the system either being offline or simply unable to communicate with the MP. Check if these clients are up and running, and also check the LocationServices.log on the problematic clients to see if there is any useful information about the communication failure.

2,Please help make sure that there is no firewall or anti-virus to stop the communication between the clients and the MPs. Use the following URL to verify that a client can access the management point and the management point certificate information:

http(s)://<ServerName>/sms_mp/.sms_aut?mplist

http(s)://<ServerName>/sms_mp/.sms_aut?mpcert

Where <ServerName> is the NetBIOS/FQDN for the management point computer.

3, Here are some more explanations for client status and heartbeat discovery for your reference:

To mark the client Active / Inactive based upon Discovery data, is based upon setting specified under Monitoring > Client Status > Client Activity. Right click the “Client Activity” and select “Client Status Settings”. Hence your client will become inactive if they are not able to send request back to SCCM Server through:

Client Policy Request

Heartbeat discovery

Hardware discovery

Hardware Inventory

Software Inventory

If client is unable to send status message based upon above 5 settings, then it will be marked as inactive.

Heartbeat Discovery differs from other Configuration Manager discovery methods. It is enabled by default and runs on each computer client (instead of on a site server) to create a DDR. Client will send DDR (Data Discovery Record) to management point. DDR can manually be sent by “Discovery Data Collection Cycle” under Actions tab through “Configuration Manager” Icon under Control Panel. If a client system has not heartbeated, then it is probably offline, not connected, or having issues and needs to be explicitly investigated.

Hope it helps. Thanks for your time.

Best regards,

Simon
