Need some help with a DNS issue

post #1 of 18
Thread Starter 
i setup a server a while back at work and was in a hurry so i didnt pay much attention to it since everything was working correctly or so i thought.... some of the people here have been upgraded with laptops rather than desktops and now i have noticed an issue.

my server is assigning static DNS entries but nothing else, pic is attached. its something with the DC since its only on domain computers and i never noticed it on the desktop PCs since i never needed to change anything with the IPs ad the client computers dont have the rights to change it. the issue is that since it is setting a static DNS entry i must allow the computers to have the rights to change it (and teach them how) so when they go out of the office they can do web searches.

i am sure it is something simple i am overlooking but i cant find a GP or anything to fix this issue.

We handle everything through DHCP and domain registration through computer names. Why do you need to assign the DNS manually, why wont it detect it itself?

This.

You could also put 8.8.8.8 as an alternate for when the primary doesn't respond outside of that network. Not sure if that would align with a 'best practices' approach, assigning DNS targets through DHCP is both much more elegant as well as typical/preferred.

i didnt do that, the computer does it at log on and that is the problem. if i turn on a computer from a cold start and log into windows that is what it looks like. how do i fix that?!?! its something in the domain obviously since it is changing it but i cant find a GPO that says anything about that. its something in the DNS or DHCP settings.

First off this is in the wrong section as you should be asking for help for Windows Server. You need to run the DNS service on the DC or on a separate DNS Server if your company has a security policy for the DNS not to be on the DC. Alternatively DNS could be setup on your router, and since you specified this is for a business then the config for a cisco router would be similar to the following

conf t
ip dhcp excluded-address 192.168.2.129 192.168.2.254
ip dhcp excluded-address 192.168.2.1 192.168.2.5
!
ip dhcp pool vlan2
network 192.168.2.0 255.255.255.0
default-router 192.168.2.1
dns-server 192.168.0.5 8.8.8.8
lease 0 10
end
copy run start


Granted this is also setting DHCP on the router or Layer 3 switch also.

DNS is running on the DC, i had DNS setup on my router but it is now running as a guest access setup with my DC and everything behind it as the business side of things. its a small business and i cannot afford much more than the 2 servers. we are talking less than 25 users but several guest users a day and they need to be away from the main network.

OK lets start from the top. Your DC is assigning the IP according to the pic you posted. It is not assigning the DNS which is where your problem lies. I just had to straighten out my Junior Sys Admin and put on my Systems Engineer hat back on from 12 years ago. Start the DNS service on the DC. Right click on the DC in that service and select IP forwarders. Then either put in the DNS Server assigned from your ISP, Googles DNS (8.8.8.8) or Open DNS (208.67.222.222 or 208.67.220.220). I prefer using OpenDNS since they will filter malicious sites from their Query table. The other option would to be to utilize root hints http://technet.microsoft.com/en-us/library/cc758353%28v=ws.10%29.aspx
Regardless of what you decide to go with start here. http://technet.microsoft.com/en-us/library/cc783205%28v=ws.10%29.aspx
As I stated before you could setup DHCP and DNS on the router, but since you have decided to utilize your DC for this you should be asking for help in the Windows section or go straight to the source and read technet as it explains the step by step ways to set it up.
