Systems Management

I am having an issue with SCCM CB showing the clients in the correct AD sites.

My boundaries are using AD Site containers.

I am trying to troubleshoot but not sure where to start. Most of the systems are showing in their correct container in SCCM

however some are not and I have confirmed they are not in the container that SCCM says they are in.

I have device collection based on the AD site container so that is throwing some clients in different containers.

I have tried deleting the client, then re discovering it. That doesn't work.

Any info is appreciated.
