If no configured DNS server responds to a direct pinging of its IP address, this indicates that the source of the problem is more likely network connectivity between the client and the DNS servers. Verify that the client can contact a preferred (or alternate) DNS server by pinging the preferred DNS server by its IP address.įor example, if the client uses a preferred DNS server of 10.0.0.1, run this command at a command prompt: ping 10.0.0.1 If the client does not have a valid TCP/IP configuration, use one of the following methods:įor dynamically configured clients, use the ipconfig /renew command to manually force the client to renew its IP address configuration with the DHCP server.įor statically configured clients, modify the client TCP/IP properties to use valid configuration settings or complete its DNS configuration for the network. Verify that the client has a valid IP address, subnet mask, and default gateway for the network to which it is attached and being used.Ĭheck the DNS servers that are listed in the output, and verify that the IP addresses listed are correct.Ĭheck the connection-specific DNS suffix in the output and verify that it is correct.
Open a Command Prompt window as an administrator on the client computer.
