@scottalanmiller ZT Range is 192.168.191.x/24

So you have a mismatch. What you showed above is not in this range.

WLS-ITGuy

@scottalanmiller I don't see where though...Or how for that matter.

This will also mean that you need to put the ZT IP address of your DNS server on the ZT NICs on Laptops that leave the physical network.

Edit: The caveat here will be if your DNS server responds with a LAN IP address instead of a ZT IP address for a device that is not located on physical LAN.

This is the continuing problem. your office DNS will have two or more IP's for laptops that live in the office at least part time. for example - if your laptop is at the office, and using DHCP from Windows, with DNS auto register enabled, all laptops will have two IPs in DNS. That LAN IP will not be automatically removed just because you go to StarBucks. So now, when the server goes looking for your laptop, it will find two IPs.. one of which will not work because it's not on the local network at the moment.

The same goes for Servers in a situation where you have a non ZT device on the local network. Local devices that don't have ZT installed are known to get a DNS response for a ZT IP address, and this of course causes problems.

WLS-ITGuy

@Dashrender All devices on LAN or off LAN have ZT installed.

That's where I am confused. Can you post the results from an nslookup of the server name from the machines that do not work?

WLS-ITGuy

Sure - any specific commands?

If not, I get:

Default Server: Unkown
Address: 2602:306:8b7e:f60::1

WLS-ITGuy

Let me ask this question...

We are a subdomain of the main branch organization. They have rmoved to Office 365 but we cannot be a part of that move. Don't get me started on that part.

Could this be part of the issue?

I don't see how but at this point I am looking at everything.

nslookup servername

If that returns nothing, check your DNS settings. What server is it trying to reach?

O365 doesn't have any components that would be involved here.

@WLS-ITGuy said in ZeroTier Question:

Default Server: Unkown

This implies that there is no default DNS server listed on that host. Is that right?

Looks like that to me.

Let me explain a bit.

www.wels.net is the main org

www.wls.wels.net is us.

The main org went Azure and Office 365 but due to costs we weren't going to move to office 365.

Could it have something to do with their DNS of www.wels.net being pointed to Office 365?

Show us the output of

ipconfig /all

?

That would depend, but only in so much as finding things for Outlook setting itself up to find Exchange, etc, activesync for phones. It won't affect DNS itself for finding servers inside your organization.

Are their email address - username@wels.net
and your email address - username@wls.wels.net?

If so, those are two different DNS MX records. They can each go anywhere you want them to.

That is correct. Exchange works fine as it is. I was just wondering if *.wels.net was getting sucked into Office 365 somehow.

We have noticed a few issues with people who are trying to access their Microsoft Accounts getting errors saying that there is no account for them at WELS Cloud.

I would think in your case, you wouldn't want to have a *.wels.net record because of problems like this.

Sorry - I meant the * as wls.wels.net

@Dashrender said in ZeroTier Question:

Sounds like you have a DNS issue. You might not be able to use short NetBIOS type names.. you might have to move to FQDN instead.

For example, if you're at StarBucks and the DHCP server gives a suffix of starbucks.com out with the IP, and you ping server1, your system might be pinging server1.starbucks.com instead of server1.yourdomain.com

I missed this or it didn't click. So you're saying that I might have to go to wls-dc01.wls.wels.net instead of WLS-DC01, correct?
