We have a new secondary site and for some reason the clients are attempting to connect to the Primary site management point despite there being a management point on the secondary.
The site boundaries are defined by AD site. The subnet that the client resides on and the subnet that the secondary site server resides in are the only ones in the AD site. I have checked for overlapping boundaries.
For some reason, the SCCM client is attempting to connect to the Primary site management point which it is unable to do so due to a firewall restriction.
