Hi all, Need help on a DNS issue

[bmquiroz]

Hi all,

Need help on a DNS issue I am having. I am using my internal home lab DNS server as my primary NS server and a 3rd party Dynamic DNS server as my secondary. Here is the problem: When I do an MX query for my domain using dnsstuff.com it returns that my primary NS server has no MX record. I have created an MX record (Forward/Reverse)in the appropriate zone. However, when it queries my secondary NS server - it is able to find the record. I'm not sure what else needs to be configured on my Windows 2000 DNS server - I have opened UDP/TCP 53 on my router. Any help would be appreciated.

On your primary nameserver open a command prompt. Type nslookup and then hit enter. Type set querytype=any and hit enter. Type your domain name and hit enter. Copy and paste the results here. Make sure you edit sensitive info that you do not want public

Here are the results:

C:\>nslookup
Default Server: localhost
Address: 127.0.0.1

> set querytype=any
> mydomain.com
Server: localhost
Address: 127.0.0.1

mydomain.com internet address = 10.0.0.1
mydomain.com nameserver = ns2.tzo.com
mydomain.com nameserver = ns1.mydomain.com
mydomain.com
primary name server = ns1.mydomain.com
responsible mail addr = administrator.mydomain.com
serial = 503
refresh = 480 (8 mins)
retry = 120 (2 mins)
expire = 604800 (7 days)
default TTL = 3600 (1 hour)
ns1.mydomain.com internet address = 10.0.0.1

Should ns1.mydomain.com show my private ip address or external address?

It should show a public IP as no-one outside your network would be able to connection to it. You might want to check what ns1 is pointing to in your forward lookup zone, it should be a public IP not a private IP.
