DNS question with FQDN

ranjitcool

Hey Guys,

I setup a windows 2008 box at home and have a AD going on it with DNS and DHCP on the same box.

Now I have a server added to the domain called STREAM.domain.com

Now when i do a nslookup for stream or STREAM or even stream.domain.com - I get non-existent domain.

When i do a nslookup for STREAM.domain.com - it works and returns the ip.

How do I get it to reply to STREAM and how do I get it to ignore the lower/upper case?

Thanks
RJ

To make sure I understand the issue, you are getting different results with 3 different NSLOOKUP queries?

C:\>nslookup
Default Server: <your primary DNS server>
Address: <your primary DNS server IP>


> STREAM
Server: <your primary DNS server>
Address: <your primary DNS server IP>
*** <your primary DNS server> can't find STREAM: Non-existent domain

> STREAM.domain.com
Server: <your primary DNS server>
Address: <your primary DNS server IP>
*** <your primary DNS server> can't find STREAM: Non-existent domain


> stream.domain.com
Server: <your primary DNS server>
Address: <your primary DNS server IP>
*** <your primary DNS server> can't find STREAM: Non-existent domain

Your resolution could be coming from NetBIOS, WINS, etc and not pure DNS. Pure DNS does not care about case.

Yes you have got it right - how do I fix the netbios wins issue? I am not using either here.. Also I tried doing some group policy changes but when i enforce the policy in AD it doesnt apply to all the clients right away.

The computer you are querying from, is it joined to the domain and the primary DNS server is set to the IP of the box that DNS is running on? Also, if domain.com is not the connection specific dns suffix or domain.com is not in the suffix search list you will not get the correct reply with hostname only, that will be returned via NetBIOS. When you do a FQDN search for STREAM.domain.com and stream.domain.com can you show me the difference?

Hello,

No my laptop is not joined to the domain. It just gets the dhcp ip from the dhcp server which lists it to use the dns server (AD DNS server).

ok, so that leaves out using the hostname only. What difference do you get with STREAM.domain.com and stream.domain.com?

Sorry for late reply but now it works just fine. I am not sure what may have changed huh. One issue i am having is that when i go to my site www.domain.com which is hosted externally, its resolving within my AD domain and never reaching my website. What do i have to do in the DNS to say for any www request go to that ip - oh wait do I add a A record?

Did you setup 'forwarders' on your local DNS server?
