Stop DNS queries at DNS Server

Posted on 2014-02-09

Hello All.

We have a few non internet connected workstations.
I'd like to know if it would be possible to stop all these workstations' DNS queries at the AD DNS servers?
In other words, I don't want any of the DNS queries coming from these non internet connected workstations to go through to the internet. I'd like to either stop this at the AD DNS server, or block them, without having to touch the firewall or use another device.

Any help would be great.
Thanks.

A workstation needs the AD DNS to logon to the network. I'm assuming you want to deny these workstations access to the internet. There are better ways of doing this than messing with the DNS. Like:
 - Change the gateway IP on the workstation.
 - Apply a policy, for a fake proxy server.
 - Setup the local Windows firewall to block traffic that goes outside your network.

In other words, leave the DNS alone. It's too important.

Kind regards,

M

Thanks M.

I kina thought it might be a little too tricky to do this on just the AD DNS server.
Our environment is a little more complex than that, but I think I'll have to do something else to stop the "noise" coming from the workstations.

I'll award you the points anyway. Thanks.
