I have a dilemma where I have machines as part of a domain and others that are attached to a different domain(not controlled by our company) but connect back to our network via F5 Networks BigIP client. There is a necessity to be able to manage and also deploy software\updates to those machines on the separate domain as well as do inventory. Our current setup is SCCM 2012 allowing intranet and internet connections. We use PKI certs for all our machines including the ones that are on this separate domain. I have modified the Hosts and LMHosts files and checked the netbios cache and the machines are configured to see our management point. However, these machines always show as inactive and I cannot contact them.
Is this because they are on a different domain and because they have no schema in their AD?
What might I be missing? Is this even possible?
