I've got a Windows 2012 server set up as a domain controller and DNS server in my basement. On my laptop, if I set it to use the IP address of my server as the DNS server, then it works as expected. The problem with that is that I use my laptop outside my home network and I need to switch it back to automatic.
Setup is like this: ISP > Router running DD-WRT > Win 2012 DC/DNS and other network computers
How can I have my laptop find the DNS server automatically instead of using my ISP's DNS servers?
