Problem: CONFIGURATION MANAGER DID NOT FIND A SITE TO MANAGE THIS CLIENT
Solution: Enable Fallback Site in SCCM
In SCCM, go to Administration
In Administration Panel, click Site Configuration - Sites
Click Hierarchy Settings
Tick “Use a Fallback Site”, Choose the Site name you created and click ok
Now go to the affected computer, open control panel and click configuration manager
In Configuration Manager, go to site tab and type the “Site Code”
Click Find Site
Now this seem to be working fine 😊
Trust the LORD completely, and don't depend on your own knowledge. With every step you take, think about what he wants, and he will help you go the right way.
