When connected to my networkusing Dhcp I can't connect to the internet using an auto configuration script.

Which settings do the script make? How does it work if you manually run the script? Please export the information of IP configuration after running the script and paste it into your post. Please run cmd with administrator privilege, and enter the command "ipconfig/all > %userprofile%\Desktop\ipconfig.txt", then open the file ipconfig.txt, paste the contents into your post. If it is possible, please also let us know the network configuration related contents of the script.Arthur Xie - MSFT
