Configure DNS server details outside NIC properties GUI

[Roeee]

All,

I need to find a method of specifying within the OS the IP addresses of the DNS servers are on the network. However, for security reasons, I need to do this outside the normal NIC GUI [ NIC --> Rightclick --> IP details].

There is a switch within the LMHOST file to say which server is a domain controller [#DOM] but not one for a DNS server??

Ideally, the answer would be a list of servers with IP addresses which are written in a text file and cached. When a DNS lookup is initiated this list would be queried and the lookup subesquently sent to the respective DNS server.
At no time can I have the DNS servers referenced within the "primary DNS server" or "secondary DNS server" inside the NIC GUI.

Thanks...

If you use DHCP to hand out IP addresses, you can specify what the DNS servers are with option 006. In the NIC properties, you specify the computer to get the IP address and DNS servers automatically and do not list any DNS servers there. If you are trying to keep your DNS servers from view, that will be hard because you can also view it from IPCONFIG.EXE /ALL in a command prompt.

Unfortunately the IP is static so no DHCP server is used.

Like you say I need to keep the IP's of the DNS servers as guarded as possible. If I enter them within the NIC properties GUI you can simply query them via a number of commands from the CLI.

Trouble is that, no matter how hard you try to hide these, a simple NSLOOKUP will reveal the current DNS server in use

Yep, there are quick one liners which will pull back the DNS server's address, though I can restrict who has access to run the commands on the box.

I need a method of enabling DNS lookup without making it obvious the IP of the DNS server.
