If you have pushed the SCCM clients on workstations from Configuration Manager Console and few of them are not showing active. Go to Monitoring > Overview (Left Pane) > Client Status > Production Client Deployment.
You will the graph under "Client Deployment Failure Detail". Click on the graph to see the workstation names on which SCCM client is not installed.
Select any workstation, there would be a status window underneath of it. In summary tab, come in the last and see the error. Example of the common error which comes mostly.

Few below things and it would be solved for you.

- Check its name resolution. If need, fix its Host and PTR record.
- Check "Server Service" on client. It should be started.
- Check "Remote Registry Service" on client. It should not be disabled. Enabled and started.
