Netsh.exe is a network administration tool that allows you to configure and monitor Windows-based computers at a command prompt. With the Netsh.exe tool, you can direct the context commands you enter to the appropriate helper, and the helper then carries out the command.

netsh interface ip set dns “Wireless Network Connection 3” static [dns server ip]
netsh interface ip add dns “Wireless Network Connection 3” [dns server ip] index=2
