How to automate DNS server reconfiguration for TCP/IPv4 and TCP/IPv6 in Windows 7?
Solution 1:
From elevated command prompt (or from .bat file):
netsh interface ipv4 set dnsserver "Wireless Network Connection 2" source=static addr=8.8.8.8
netsh interface ipv4 add dnsserver "Wireless Network Connection 2" addr=8.8.4.4 index=2
or
netsh interface ipv4 set dnsserver "Wireless Network Connection 2" source=dhcp
You can just replace ipv4 with ipv6 (and proper address of course).
Solution 2:
In powershell:
$wmi = Get-WmiObject win32_networkadapterconfiguration -filter "ipenabled = 'true'"
$DNSServers = "8.8.8.8","8.8.4.4"
$wmi.SetDNSServerSearchOrder($DNSServers)
To revert:
$wmi.SetDNSServerSearchOrder()
(no parameters=null, this will put it back in automatic mode)
