The SonicWall cannot resolve DNS names

Description
If the SonicWall cannot resolve DNS names to IP addresses, it cannot contact the DNS servers. This may cause the SonicWall to be unable to reach the content filtering service, set the time on the appliance using the NTP servers or synchronize licenses. Make sure the DNS server IP addresses are configured and they are correct (Network|DNS Settings page in SonicOS Enhanced and Network | Settings page in SonicOS Standard firmware). If you are not running your own DNS servers, verify with your ISP that you have entered the correct DNS IP addresses.
