I run my own DNS servers, each with an external and internal view with
ACL controls. So for systems inside my network, they will see the .htt
TLD, external systems will not. I understand that the actual AD zone
needs to be delegated to the AD server. AD clients will access the AD
server for DNS resolutin and it will look to my DNS server for its lookups.
Running the AD in an ad.home.htt zone makes sense. Easy delegation.

What replaces roaming profiles functionality in AD? Googling points to
group policies? Obviously my goal is for my few users to be able to log
on to different systems and get their profiles. This is complicated by
XP, Win7 and Win10 systems...

I see your point. Only a couple users and a few systems. Just have to
drop each system from the PDC and then join them to the AD. Oh, the PDC
and AD are on different subnets to keep them from stepping on each other.
But I would like a users browser bookmarks to be consistent across
systems. Also for specific programs (like Quicken) to work the same on
any system. OS version will undoubtedly be a problem. Getting rid of
the last XP systems will be good though.

Yep, I keep going back to it.
