Can't communicate with Primary DNS Server

[shslack]

We had to get a new modem. Our Apple products connected to the new network just fine and will connect to the internet and download email. Our Toshiba laptop says it's connected to the network but won't connect to the internet. It gives the error message "Cannot communicate with Primary DNS Server"

OK... try this to "Reset your TCP/IP"...

1. Press the "Windows" key and in the search box type "CMD" (without the " marks) and hit enter.

2. When you see "CMD" or "Command Prompt" in the results list right-click on it and choose "Run as Administrator".

3. When the new window loads, first type in... "netsh winsock reset" (without the " marks) and then hit enter.

4. You should get a message saying you need to restart the computer. Ignore this message for the moment.

5. Now type "netsh int ip reset" (without the " marks) and then hit enter.

6. Once that is done, close this window and reboot your computer.


You can also try the following, if the above doesn't work and after the computer restarts...

A. Press the "Windows" key and in the search box type "CMD" (without the " marks) and hit enter.

B. When you see "CMD" or "Command Prompt" in the results list right-click on it and choose "Run as Administrator".

C. When the new window loads, type "ipconfig /release" (without the " marks) and hit Enter.

D. Then type "ipconfig /renew" (without the " marks) and hit Enter.

E. Once that is done, close this window and reboot your computer.
