Change DNS settings in a (CMD) Command file.

We have a user that works at two locations. He is running Windows 10.
At location 1 he has DHCP with the DNS IP addresses he needs.
At location 2 we need to manually set static DNS for him to access some crucial applications.
We don't just leave the static DNS IPs on because this affects his normal internet access when at home or elsewhere.

I would would like to setup two command files (.CMD) that will change the DNS settings for his NIC per location.
- Command file 1 - DHCP DNS
- Command file 2 - Static DNS

What command line can I use to do this?

I don't know why you need to change current DNS to static one.
Ideally DNS should be able to handle all traffic with either creating multiple dns zones or appending dns suffix search list etc

Else,
alternate IP configuration is the better option than using software for that which completely eliminate user intervention

U can set static IP on all workstation once in other location with customized DNS settings and forget it.
When user at home, he will get IP from ISP DHCP and connect to internet.
When user comes to company, since DHCP is not available he would automatically use alternate configuration

Open Notepad and paste below. You have to make two files HOMEDNS.bat and OFFICEDNS.bat

@ECHO OFF

set vardns1=8.8.8.8
set vardns2=208.67.222.222


ECHO Setting Primary DNS
netsh int ip set dns name = "Ethernet" source = static addr = %vardns1%

ECHO Setting Secondary DNS
netsh int ip add dns name = "Ethernet" addr = %vardns2%

ipconfig /flushdns

exit

Open in new window

But change the name of LAN card. Here in my case is Ethernet so you have to check in user's laptop. Above script has been tested on my Windows 10 pro machine. If you need script in powershell I can provide.
Don't forget to change the extension to .Bat
