Client cant ping DNS Server by FQDN but by IP

October 20, 2010 at 03:04:27
Specs: Windows 7
Hallo,
I'm trying to set up a WS2K3 Domain, for which I installed Active Directory, DNS Server, DHCP Server on one Machine.

The Problem is, that clients cannot resolve the Fully Qualified Domain Name of the Server.
- I can ping the Server by IP
- I can ping the Server by name "S1"
- I CANT ping the server by "S1.hasa.local"

Client Configurations:
Clients have Router IP as default Gateway: 192.168.191.1
Clients have Server IP as DNS Server: 192.168.191.2
Both they get from the DHCP Server on the Server S1.

DNS Configuration:
Revers Lookup
Forward Lookup

Please Help me, I really do not know why DNS Server doesn't work.

P.S.
On the Server I can ping the Server itself by Fully Qualified Domain Name "s1.hasa.local" and by IP. The Client is Windows 7. The Server is Windows Server 2003.

Coming from the Unix side of the house huh?

If you go to the dns logs are there errors?
Do you have a host entry and ptr record for S1?

I have found 127.0.0.1 isn't correct for the Microsoft world. It should work but I have found too many cases where it doesn't. You should use 192.168.191.2 for the server dns entry on the server.

You will also need to go into dns server and make sure there are host and ptr records to this affect.
servername host(A) 192.168.191.2
for example

Thnx for help Wanderer,

- there are no errors in DNS Log, there are only events about start-up of DNS Service, no other events.
- Pointer and Host entries are here and here

And I changed 127.0.0.1 to 192.168.191.2 in the Server DNS Entry.
Still I can ping the server by FQDN on server itselfe, but not on the client.
DHCP works well. DNS doesnt work for clients.

Did you install this as a root dns server?

Your dns forward lookup zone doesn't look right to me.

for example my dns has in the left pane
mydomain.net

in the right pane I have
_msdcs
_sites
_tcp
_udp
along with my NS and Host(A) records.

If I expand my left pane I get
the _above as well as
domaindnszones
forestdnszones

I have no host entry here [left pane] whereas you do. All of my host and ns records are in the right pane.
You have the domain and forest entries in the right pane with host entries whereas I do not.

You also have under forward lookup zone left pane
_msdcs.hasa.local
I only have mydomain.net

If you did not have dns server installed at the time of the active directly install the wizard should have created dns serve with all the correct settings.

How did you do your dns setup?

also please post a ipconfig /all from a workstation. Thx

OK boys and girls, if you have strange behaviour affecting DNS - DISABLE THE FIREWALL ON THE SERVER FIRST !!!
