Hi @QdPooler-5995 ,
The error code 0x87d00607 means that the content is not found by SCCM/client and the reason for that can be numerous like improper configuration of boundaries or boundary groups, pre-staged content, blockage from the firewall, etc.
To narrow down the problem, we need:
1, Make sure boundary groups are enabled in the properties of the Distribution Point and check if the IPs (make sure no IP address is typed wrongly) of the client machine are included in the boundary group.
2, Check the required port to the firewall of your client machine.
3, Check appenforce.log in the client.
