Hi @Rahul Sapke ,
Thank you for posting in Microsoft Q&A forum.
1,Client status of Inactive are indicative of the system either being offline or simply unable to communicate with the MP. As these clients are up and running, please 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 client 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.
Some official articles about antivirus exclusions and firewall port settings for your reference:
Recommended antivirus exclusions for Configuration Manager site servers, site systems, and clients
Windows Firewall and port settings for clients in Configuration Manager
3, Here’s 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.
Thanks for your time. Have a nice day!
Best regards,
Simon
