Setting the ZT IP addresses of my two on-site DCs in the V-NIC on the client works. Should this be a short term fix only?
Setting them as DNS? That seems like a good solid fix. So you are getting reliably good DNS results now? I think that you are good to go
Right, but you need to be aware that your internal DNS server will now be queried for everything and return results appropriately.

@JaredBusch Won't it look at ZT first, realize it isn't on the ZT network, and then dump off to the end users ISP?

Not for DNS. DNS queries happen only once. And it WILL be on the DNS server if it is set up correctly for the office to work.

@scottalanmiller I was thinking Gateway

I see a problem - How does the mobile PC find the ZT controller when it out and about? When will the mobile PC decide to use the DNS servers provided by the real network card vs using the DNS provided by the ZT adapters?
You really do need/want both to be able to work. So you go to a new location, you connect to their network, your computer needs to use DNS to find the ZT controller on the internet (unless they are considered static and the ZT software just has an IP for the controller - then nevermind), but assuming it's not FQDN based for controllers, you'll need to use the physical NICs DNS to find the controller, then after you ZT network is up, you can switch full time over to use the domain's DNS for anything/everything.

The general traffic will not be on ZeroTier, no. But that is not what I said.
I said the DNS traffic will all be on ZeroTier. Every single lookup will go to your internal DNS server and return whatever address it knows for the query in question.
Example:
oc.domain.com returns 1.2.3.4 on public DNS.
But on my internal DNS server oc.domain.com is a CNAME for oc.domain.local which is has an internal IP of 10.202.1.12
But by ZeroTier scope is 10.202.3.0/24 and that server does not have ZeroTier on it. -

Yes, if the DNS returns a non-ZT address as the answer and it is a public IP address, it will be sent to the default gateway, not over the ZT LAN.

For traffic, yes it will, but not for DNS queries.

If the ZeroTier controller is not available, the ZeroTier adapter will not be online, so the local DNS will apply.

When connected versus when not connected. It doesn't look to the ZT controller's DNS settings when that controller is down.

Good to know - OK that problem's solved. +1

FYI - Not like you didn't know this but THIS PLACE IS AWESOME!
Thanks for all the help. If this works I won't have to listen to professors complaining about not being able to access files from China.

And this is your first issue.
Give it a few months, you'll need even bigger CAPS.

I may have spoke too soon. With the hard set DNS it doesn't allow Outlook to work. Via WEb or Client

Start with.... what's not working? What wrong info is it getting? Does Outlook or Web work from the office?

@scottalanmiller Outlook client doesn't connect. Keeps asking for password. Webmail says page not found. All offsite. Everything works on campus.

But these same services work for people on the same DNS when they are in the office?

Works for me running a mac. Works for other machines that never leave the network. Those that never leave I didn't set to a static DNS on the ZT nic.
-
I suppose my other option is to do mapped drives via ZT IP address and remove the static DNS.
