asked on

My network, is this correct + added question about DNS forwarder

I recently found out the cause of my former problems, I was having major problems joining my domain from one particular client. The problem was due to the fact that I used two NICs on my server, and someone on googlegroups suggested I buy a switch. So I went back to the drawingboard and drew up this diagram of what I think my new setup should look like,

As for specifics,

PC1 will be running Windows XP professional
PC2 will be running Windows Server 2003
PC3 will be running Windows XP Professional

I'll ofcourse install active directory and DNS on PC2 so that my clients can join the domain, then I also received a reply from someone there who said the following,

"The DNS server has to become a Forwarder for the ISP's DNS"

I think with this he means that my DNS server supplies my clients with the DNS server of my ISP, so my clients can surf the internet, but its here that I have a problem, I do not know how to set this up. Also could I not just do it like this,

so that my clients have 2 DNS addresses, the server DNS for domain and lanstuff, and the second alternate DNS to go to the internet?

Hope you can answer my questions better then last time, cuz noone could solve my problem.

Question 1 for MSE-Dwells : Could you elaborate on this sentence, I do not know what you mean,

"Do not configure the client's alternate resolver to point to another DNS server unless it too has the zone that represents Active Directory"

Especially the part starting from "unless it too....."

Question 2 for vsg375 or others : I checked out that site and when it talks about setting up a forwarder, but there its explained for windows 2000, I made a screenshot for my windows 2003,

http://i15.tinypic.com/62dgbc3.jpg

so I assume I just fill in the IP's to my ISP just in front of that ADD box, and click ADD? Also do I leave that 'ALL OTHER DNS DOMAINS' just as it is, because you can also click the NEW button there and then a box pops up stating 'NEW FORWARDER'.

Question 3 for everyone : What do I do with this,

http://i16.tinypic.com/5ym0eg5.jpg

do I keep all these servers there, or will my DNS use these when my ISP DNS is down??

Question 4 for Chris-Dent : You say, Forwarders are optional, some people like to them, others don't. If you don't use them your server will attempt to resolve requests using the contents of the Root Hints tab. Why do some people not like them, if your ISP has never went down, then is using forwarders not best, I know and trust my ISP and its fast, so why would I choose to go through slow DNS servers across the globe when I can use my own DNS server in my country. Also if you set up forwarders like you stated, does that mean that this takes precedence over any root hint servers in DNS.

Also, do I need to create any reverse lookup zones in my DNS?

If all these questions are answered then I think I'm ready to set up my new network, so then I'll decide who has been the best help to me. Thnx so far for answering these questions.

Oh yeah, just a short note :)

Note that you can split the points between us if you find that we've all provided helpful responses rather than picking a single answer.

Okay I think I am ready to set up my new network, all it takes now is to get my switch, I first didn't use a switch and this caused all sorts of problems(with me having to use 2NIC's on each comp).

And yes this question is now answered to my satisfaction, so will accept multiple solutions as all contributed very well.


Good luck :)
