Of course SCCM was SMS. More recently they dropped the “Endpoint”
Only because they wanted to re-brand Intune as Endpoint..
(I remember SMS - when I was doing y2k stuff we used it to push out patches.. Ah the fun we had as suceeding patches either changed the date display rules or broke previous patches. I was mostly doing Unix & firewall patching [1] but still go involved on the Windows side when the poor little dears [2] needed someone with actual technical skills [3] to help..)
[1] Out of the 40 or so people on that contract, I was the only one that had used anything vaguely unix-like - I'd been using linux for about 5 years by that point. And I'd managed a firewall at my first techie job (put in a 64k leased like with a Sun box running Firewall-1) so was the most qualified person in the team.
[2] Let's leave it at the fact that most of them were barely-qualified MCSE types and, if they came across anything not covered by their courses, lacked the ability or experience to actually do anything.
[3] By that point I'd herded DOS, Windows 3+, OS/2 (all flavours), a bit of S/370 herding, Windows NT Server, OS/2 LAN Server, linux (at home).. So I was quite used to OS-context switching (like I am now - my main machine is a Mac but I have work-build Windows VMs for when I need to manage Windows stuff (like SCCM) that isn't done via a web point-n-drool.
