makes me wonder if the router at the coffee shop was taken over and is doing bad things...

Was that IP obtained while at the coffee shop? or did I miss it and it was really someone at their home?

This one is at home.

What do they have for DNS servers at home? Their ISP? I've seen many ISPs (Cox does this) if you put in a bad address, you get redirected to a bad website request page hosted by Cox instead of getting an invalid domain name as you might rather have. They are trying to making things more understandable for consumers, sadly it just screws us instead.

Have you home user change the DNS provided by their router (if possible) to Google's 8.8.8.8 and 8.8.4.4 and try again.

I've got $1 that says I can name the ISP of the home user...

(Pro tip: It's mine too).

AT&T? Cause that is mine too and I think I got the same address

Naw... I bet your home-user's ISP is Charter?

Except in the case of the end-user's machine not actually hitting the internal DNS, maybe?

Sure, but if the user isn't hitting an internal DNS, where would that address come from at all? I would expect it to simply fail, or get a *.wls.wels.net reply back, which isn't happening when I ping, so no reason to believe that would be happening to the home user.

F[moderated], I said it. It is coming from his primary DNS like it should.

Most likely it is his ISP hijacking the bad DNS results and will show a search page if he were to use a web browser.

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. That magic way that everything works on a LAN without DNS.

Yes it does. In my experience, over VPN type techs (like Pertino, ZT, OpenVPN, etc), Netbios has not been reliable.

Dashrender

@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 hosts file with the ZeroTier IP of one of the domain controllers and the domain suffix like this:

10.202.3.21    domain.local

Then 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.

WTF? What problem? I just said it was reliable on ZeroTier.
