Windows 10 batch file dns

I have two batch-files, one to change my DNS to Unblock-US, and one to reset it to DHCP. These worked perfectly in Windows 7 and 8/8.1, but after upgrading to Windows 10 i can no longer reset it to DHCP.

Unblock-US batch:

netsh interface ipv4 set dns "Ethernet 2" static 208.122.23.22
netsh interface ipv4 add dns "Ethernet 2" 208.122.23.23 index=2
ipconfig /flushdns

DHCP batch:

netsh interface ipv4 set dns "Ethernet 2" static dhcp
netsh interface ipv4 add dns "Ethernet 2" dhcp index=1
ipconfig /flushdns

Anyone have an idea what may be wrong?

1Do you get an error message? Have you tried running as Admin? – DavidPostill – 2015-10-15T07:32:15.350

1Is the adapter definitely called Ethernet 2? – CharlesH – 2015-10-15T08:03:14.613

@DavidPostill: No error message, it just won't change it to DHCP. I'm running as admin – Jens-Christian Christiansen – 2015-10-15T08:06:35.440

@CharlesH: Yes, it is Ethernet 2. It will change to Unblock-US, but not back to DHCP – Jens-Christian Christiansen – 2015-10-15T08:07:31.767

In netsh interface ipv4 set dns "Ethernet 2" you should use either static or dhcp but not both together, see netsh interface ipv4 set dns /? – JosefZ – 2015-10-15T10:20:42.563
