There are two possible situations that the NAS will show the DNS error message.

1.    DNS server address error

       * If the NAS is configured to use a static IP address, check that the DNS settings are correct in "System Administration" > "Network". If you are not sure about the DNS address, contact your ISP (Internet Service Provider) or use google DNS server, 8.8.8.8 and 4.4.4.4.

       * If the NAS is configured to obtain DNS server address automatically, check the DHCP server and make sure the server provides the correct DNS information.

2.    Default gateway address error

       * If the NAS is configured to use a static IP address, check the default gateway settings and input a correct gateway address in "System Administration" > "Network". If you are not sure about the default gateway address, contact your ISP (Internet Service Provider).

       * If the NAS is configured to obtain the default gateway server address automatically, check the DHCP server and make sure the server provides the correct default gateway information.
