Issue Reported: None of the client are able to register with SCCM 1610 and getting error as below screen shots.
Step 1: Verify random client properties and found Client certificate shows as None.
Step 2: Verified AD level DNS record as showing error on LocationService.log, Found finding records is not available in active directory as client contacting other DNS which no longer active.
Step 3:Go to the client system â€“> Click on run â€“> Type control smscfgrc and enter
You will see Configuration Manager Properties â€“> Click on Site Tab and enter site code which is showing in AD as here example H01 click apply and okay.
Step 4: Wait for while and look the LocationService.log /ClientIDManagerStartup.log you will see client get register as well as client get certificate based on configurations. Here its showing as Self-Signed.
After doing above steps client start reporting to as normal and issue fixed.
