DNS Help... newbie here 2

[cranebill]

I believe i am having DNS issues but am not for sure about this. So i tried to gather all the info i could to post this question.
I have a 2000 Advanced Server as a domain controller. This is set up as a new domain. I have 2 nic's installed. One for Interent... one for lan. ICS is enabled. I have set up OU's in the Active Directory and when i try to apply Group Policy settings to the OU i get this error:

Domain Controller not Found for Sample.com

The Domain Controller for Group Policy Operation is not available. You May cancel this operation for this session or retry using one of the following:

1. The one with the operations Master Token for the PDC emulator.

2. The one used by the active directory snap-ins

3. Use and available Domain Controller

(none of these work)

I have asked around these forums and everything seems to check out although it has been said i may have a DNS issue.

Right now i have one WorkStation (XP Pro) connected to the Domain . I have run nslookup and this WorkStation and this is what i recieve:


*** Can't find server name for address 192.168.0.1: Non-existent domain
*** Default servers are not available
Default Server: UnKnown
Address: 192.168.0.1

This really doesnt make alot of sense to me since i am connected to the domain.

I also ran ipconfig on the server to determine ip configuration and this is what i have:

Does this all seem right... or no?

MVP,

I think that is what I was trying to state. Maybe I confused it by not wording it correctly. Of course, he needs to enter the IP Address of the ISP. On one of my replies I clearly note it:

==>Then in DNS under Forwarders you want to enter the IP Address of your ISP<

 

[devastator]

Why use forwarders when you can just use the root servers that are listed in 2000? Along with the ROOT servers I just added by ISP's DNS servers to the list and don't have anything in the forwarders and am running internal DNS only and everyone can get out onto the Internet through our Internal DNS IP's.

That's what was confusing me for awhile with everyone saying I needed forwarders to resolve and others saying not to use them. I removed them to see what happened and well, I could still get out on the Internet.

Devastator,

This is what I was basing my opinion on the forwarders:

http://support.microsoft.com/default.aspx?scid=kb;en-us;291382

(See first question and answer from this article)

 

[devastator]

Question: If I remove the ISP's DNS server settings from the domain controller, how does it resolve names such as Microsoft.com on the Internet?

Answer: As long as the &quot;.&quot; zone does not exist under forward lookup zones in DNS, the DNS service uses the root hint servers. The root hint servers are well-known servers on the Internet that help all DNS servers resolve name queries.

As stated from that article. Just throwing out some ideas.....

Devastator,

I'm taking that statement from the article that the &quot;.&quot; zone needs to be deleted. My understanding on this is for the clients to resolve names such as microsoft.com the &quot;.&quot; zone gets deleted in DNS, then from your DNS tab you click &quot;Forwarders&quot; then enter the IP Address of your ISP. You also may need to add a new host in DNS to help resolve external names. Also important if clients connecting via DHCP to make sure the DHCP options 006 and 015 are defined properly and on the DNS tab from DHCP properties to make sure this is setup correctly. There are many factors that play into it of course depending on the environment.

Well this is what i have done so far....

I deleted active Directory
Reinstalled it
Manually configured DNS and DHCP

Now all problems that i was having on the active directory side are solved. As of right now noone but the server however has internet access.... that is something i will tackle tomorrow though... thanks for all the help guys.
