Hi D,
Thank you for posting in Microsoft Q&A forum.
The error code 0x8004100e means "Invalid namespace" and 0x8007007f means "The specified procedure could not be found".
1,How many clients are facing this issue? Can we manually install the SCCM client agent?
2,Please check your boundaries and boundary groups configurations, and associate your MPs and DPs to the boundary groups. Make sure the client can communicate with the MPs and DPs.
3.Please also make sure your Firewall doesn't block the communication between the client and site system servers.
For more detailed troubleshooting steps, please refer to the helpful article:

Thanks for your time. Have a nice day!
Best regards,
Simon
