2. Make sure you are using the correct DNS server

There are a few steps you can take to make sure you are using the correct DNS server in order to fix error code 12007 4. First, you can check to see if your computer is using the default DNS server. To do this, you can open a browser and type in "ipconfig" into the address bar. If your computer is using the default DNS server, the address bar will list "IPv4 Address." If your computer is using a different DNS server, the address bar will list "Default Gateway." Next, you can check to see if your computer is using the correct DNS server by trying to resolve a domain name. To do this, you can open a browser and type in a domain name, like "google.com." If the domain name can be resolved using the default DNS server, the address bar will list the domain name and the "www" portion will be blank. If the domain name cannot be resolved using the default DNS server, the address bar will list the domain name and the "www" portion will be filled in with the IP address of the default DNS server. If the domain name can be resolved using the correct DNS server, then you can assume that your computer is using the correct DNS server and you can move on to the next step. If the domain name cannot be resolved using the correct DNS server, then you will need to contact your ISP or the administrator of the domain name to change the DNS server.
