Mx DNS propagation problème

You posted matpbnet.ma as your DNS provider.

Also post your domain name + likely someone can assist.

AD domain local is matpb.local, I hérités it from the previous installation. I create a primary zone and integrated it to AD "matpbnet.ma" I create in this zone www as a CNAME, mail.matpbnet.ma as mx pointing to my exchange server.

So matpbnet.ma is your domain. Yes?

Yes thank you

Problem #1...

If matpbnet.ma is your domain, then you have no NS records set for this domain, so no other records can be resolved.

imac> dig +short matpbnet.ma ns
imac> 

Select allOpen in new window

You must have a valid zone setup for your domain, as a first step...

So NS records + A record + www CNAME + MX.

Where it must be exist. At my Provider or in my dns zone ? Because in my dns zone, I have the record ns pointing to my server

What i can find, this server is listed as your NS
Name Server: ca1sw03.matpbnet.ma

but when asking for it, it doesnt respond. Check with your provider where you host your DNS is everything is correct there. Otherwise move your zone to another provider that can help you

As Carlos stated, your DNS starts with your Registrar, so if you registered your domain at matpbnet.ma (which it appear you have), then you'll login your account there + input your DNS records, then your records will be compiled into a zone file, served by their DNS servers.

Use dig (or nslookup on Windoze) to test your setup.

Trying to guess why DNS is broken... rarely works. Use dig/nslookup + debug your DNS step by step + you'll save a great deal of time.

I send an email to my provider who is registrar for .ma, they create matpbnet.ma secondary zone pointing to my public IP address. It's the only way, there's no interface offered.
And I am sur there is something wrong some where but my provider tell me that I have a problem with my installation. I have windows 2016 Domain & DNS contrôler. I am really loosing

If you have to email your Registrar to make these changes, likely best for you to use some sort of public or paid DNS system to maintain your actually DNS records.

A quick searched turned up this list...
