Connect him up via ZeroTier, and set your DNS Server's ZT IP on the zt Nic, and you should be good to go.
Why. You keep saying this and I keep telling you that it is a bad idea.
I have ZeroTier running and it resolves ZeroTier IP addresses with no DNS modifications.
What are you using to do that? Your windows AD DNS?
Nothing. ZeroTier passes NetBIOS. This is really basic.
Yes it does. In my experience, over VPN type techs (like Pertino, ZT, OpenVPN, etc), Netbios has not been reliable.

@dafyre I too have found reliability to be a problem.

Let's wait and hear back from @WLS-ITGuy before we go too far down the rabbit hole.

NetBIOS is reliable when addresses don't change like with Pertino and ZeroTier.

Therein lies our problem.. He wants to use ZeroTier.

Anyway, as I linked at some point above and it was apparently not understood, i have zero problems access network resources over ZeroTier from this laptop. There is not any DNS setup. So that does mean that if the laptop never comes in the office, it will eventually lose trust with the server because domain.local does not resolve, only the machine names.
No I could easily fix that by adding a line to the
hostsfile with the ZeroTier IP of one of the domain controllers and the domain suffix like this:10.202.3.21 domain.localThen even domain queries will work. But for machines that are on and off the network all the time, it is usually not needed as they get their tokens refreshed often enough.

@WLS-ITGuy said in ZeroTier Question:
@dafyre I got the onsite vs offsite part. However, shouldn't ZeroTier handle the offsite routing? Or is that not how this works
It's not about handling routing because there would be no route.
Example
Server internal wire network IP - 192.16.8.10
________________________ZT IP - 10.0.50.10If, when you're offsite, DNS returns the 192.16.8.10 address, the ZT network would never look at this traffic because it's not part of the ZT network. Instead that traffic would go to the normal NIC, wireless probably, and go out that way and of course fail.
And this is why I default to building a ZT Gateway. Yes, it is more work up front. Yes, it is slightly more complicated. However, it prevents you from having to deal with these types of issues.
In what way? If the wrong DNS is being grabbed, how does the extra complexity of the gateway make it easier?

He meant that Pertino and ZeroTier are places where the IP does not change. Their addresses are stable. Unlike many traditional VPN services.

I knew what you meant but after reading what he responded and reading your post again I figured out that the word order could be emphasized differently to make it sound like you were saying that they were an example of stable OR an example of unstable.

In essence the device becomes part of the physical lan...this means that you no longer have to install ZT on every device ... Only those that leave the office.
Rather than having ZT IP space and LAN IP space... they become one single IP space. This means that the DNS server's won't have to randomly decide whether or not to give out a ZT IP, or a LAN IP... They only have one IP to give out... This is where the complexity pays for itself, to me. We don't have to do any fancy DNS hijacking like Pertino does.

All of the above said, it is best to setup DNS.
But you have to be aware of what you are doing and the side effects it will have, as well as the extra work it will entail.

I see, because you are not layering IPs for the servers, only for some of the clients.

That is not being talked about anywhere in this thread. Why would you suddenly curve this into something like that.
While it certainly is something that can be setup, let's not detract from the point at hand.

Scott asked the question, and I answered.

HOLY HELL! That was a Shit ton of responses.
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?
Reading through the last few posts my eyes were going wacko!

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
