If you are on Windows Vista/7/8 you will need to create the batch file and then run it as administrator.
In the examples below you will need to first know what the connection name is for your network connection(s)
When you click on the start menu or Windows key on your keyboard in the search type in “ncpa.cpl” and hit enter and that will tell you all the connections you have. Depending on what one you use or want to modify you may need to update the name in the below examples from “Local Area Connection” or “Wireless Network Connection” to something else.
Rarely is this needed unless you have already set static IP addresses
@echo off netsh interface ip set address name="Local Area Connection" source=dhcp netsh interface ip set dns name="Local Area Connection" source=dhcp
When setting a static IP address you will need to also set the static DNS
@echo off netsh interface ip set address name="Local Area Connection" source=static addr=10.0.0.54 mask=255.255.255.0 netsh interface ip set address name="Local Area Connection" gateway=10.0.0.1 gwmetric=0 netsh interface ip set dns name="Local Area Connection" source=static addr=208.67.222.222 netsh interface ip add dns name = "Local Area Connection" addr =208.67.220.220 ipconfig /all
If you choose to keep DHCP for your IP Address but have static DNS this will be what you need to use.
@echo off netsh interface ip set dns name="Local Area Connection" source=static addr=208.67.222.222 netsh interface ip add dns name="Local Area Connection" addr=208.67.220.220 netsh interface ip set dns name="Wireless Network Connection" source=static addr=208.67.222.222 netsh interface ip add dns name="Wireless Network Connection" addr=208.67.220.220 ipconfig /release ipconfig /renew ipconfig /flushdns
