Like you can see in the title, I have a server with a LAN domain (+ DHCP/DNS, AD, FileServer). After a blackout, we had to reset our routeur and APs and since then, I can't access the domain with the clients computers.

DNS error :

DNS name doesn't exist

error code 0x0000232B RCODE_NAME_ERROR

resquest's SRV target : _ldap._tcp.dc._msdcs."domain".lan

.

.

.

something like "No delegate zone for child zone"

The server's IP configuration is :

IP : 192.168.1.2

Mask : 255.255.255.0

Gateway : 192.168.1.1

Additionnal information :

The DNS server has the same IP address as the server (192.168.1.2) and is set manually on each client.

From the clients I can ping the server and access the shared folders.

I've seen everywhere that I have got to create a PTR on reverse lookup zone with the DNS IP, which I already have.

Plus : IPv6 is desactivated

Tests done :

nslookup with FQDN --> Serveur : Unknown and Address 192.168.1.2

net use on shared folder --> OK

ping FQDN from client --> can't find host

replace PTR on DNS and restart service

ping client from server --> can't reach

I checked my DNS config again and again. Maybe the problem comes from my router ?

I'm getting lost and if you have an idea I'll gladly hear it

Q.

  • please add more details, OS, configuration snippets, actual things you tested including the logs. Your network is unclear, are they all in the same subnet etc. Are you certain that the correct DNS is used by the client? Are you certain that DNS in principal is working (resolv some "real" domain on the server + client) Additionally please try to format the output. – Dennis Nolte Dec 6 '18 at 10:40
