DNS issues

Guest · Aug 3, 2004

Hello,
I have had a number of issues with my DNS srever. I am running Small Biz Server 2000 with Win 2K server SP 4, Exchange 2000 SP1. Everyting was working fine until I tried to change the default IP address on our router which is the DHCP provider. I am using RRAS on that server and have performed the steps in 292822 - Name resolution and connectivity issues on a Routing and Remote
Access Server that also runs DNS or WINS:
http://support.microsoft.com/default.aspx?scid=kb;en-us;Q292822
When I restart the DNS services I get "The DNS Server machine currently has no DNS domain nmae. Its DNS name is a single label hostname with no domain (example: "host" rather than "host.microsoft.com")"
It proceeds to tell me I may have failed to configure a primary DNS domain for the server computer and I should go to the Network Identification tab and change the domain name.
The Network Identification tab is set properly.
When I try to reload the forward lookup zone that is the same as my domain name, my SOA Primary server value only has the server name. and not the domain attached to it. Also, a Name Servers record is created with just the server name and and IP address of Unknown. There is a second name server listing that has the FQDN and the correct IP Address.
I can manually go in and correct these settings but when I reload the lookup zone they reset themselves.
Thank you,
Mark

Can you post an unedited ipconfig /all please?

Actually I needed to see the ipconfig /all unedited so I can see the primary
and connection DNS suffix.

Have you verified that the DNS proxy is disabled in RRAS?

That is in the RRAS console, expand IP Routing, right click on NAT,
Properties then on the name resolution tab. make sure the option to Resolve
IP addresses for clients is not checked.
Could you post or email me a list of the records in your forward lookup
zone? (right click on the open zone choose "Export list")

Hello Kevin,
In the RRAS console under IP Routing I do not have NAT listed. I did not set up to use NAT when I set up RRAS. Also, most of my problems started when I thought the integrated NIC was bad and I installed a new one. I have since removed that NIC and gone back to the original integrated NIC.
Here is the export of my forward lookup zone:
Name Type Data
_msdcs
_sites
_tcp
_udp
(same as parent folder) Start of Authority [189], synact1., admin.synact.net.
(same as parent folder) Name Server synact1.
(same as parent folder) Name Server synact1.synact.net.
(same as parent folder) Host 192.168.1.2
(same as parent folder) Host 192.168.16.1
SYNACT1 Host 192.168.1.2

Thank you verey much for all your help,
Mark

Hello Kevin,
The AD Domain name is SynACT.net
In the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters, the values are as follows
Domain: SynACT.net
Hostname: SYNACT1
NameServer: <blank>
NV Domain: SynACT.net
NV Hostname: SYNACT1

I can manually change the SOA and Name Server records in DNS. However, when I reload the zone or restart the services, the values without the Domain name comeback. Also, after applying the registry changes named in the MS KB article you recommended I did not notice any changes in the DNS values after restarting the services. Don't know if this info helps but wanted to pass it along.
Thanks,
Mark

Are you using AD integrated or Standard primary zone?
If you are using Standard Primary you need to delete the synact.net.dns file
in the system32\dns\backup folder.
And delete the NS record with only the host name.

And what about this record?

(same as parent folder) Host 192.168.16.1<---what is this IP for? Only DCs

should have a (same as parent folder) host record.

Hi Kevin,
This is an AD integrated zone.
I do not know why I have the record (same as parent folder) Host 192.168.16.1
I thought it may have gotten created when I set up RRAS. I would like to know where that is coming from and also the NameServer synact1.
My only Reverse Lookup Zone is 192.168.16.x Subnet and here are its values.
(same as parent folder) Start of Authority [15], synact1., admin.synact.net
(same as parent folder) Name Server synact1.
(same as parent folder) Name Server synact1.synact.net

Am I getting those strange values in the FLZ because of what is in the RLZ? I thought the 192.168.16.x was for RRAS. I do not have a RLZ for 192.168.1.x subnet. Should I?

Not likely, the forward zone can create reverse entries, but the reverse
zone cannot create forward entries.

I thought the 192.168.16.x was for

RRAS.

RAS is 172.16.1.1, even if RAS was 192.168.16.x you don't want it registered
in DNS that's the point of the registry entries. The only (same as parent
folder) entry you want is for the private interfaces of your domain
controllers, if you have a domain controller on that address it is not this
one so, I don't know why it is there. Delete it, if it gets re-registered we
can figure out why, if it doesn't, that's OK too.

I do not have a RLZ for 192.168.1.x subnet.

Should I?

Reverse DNS is not required but you can set up one if you want.

I'm not sure what the problem is at this point, DNS should not be creating
the NS record with just the hostname, all the settings seem to be correct.
I'll tell you what you can try re-installing the AD zone, i'll post the KB
below, follow it step by step to see if it clears this up, it may just be
bad data in AD doing this.
