To resolve this issue, you should ensure that the "NameServer" string in the registry key indicated below is properly configured.
1. Launch the Registry (Start, Run, and type regedit).
2. Look for the Registry key identified as
\\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\TCPIP\Parameters
3. Confirm the "NameServer" string contains the correct IP address for DNS purposes; if it does not contain the correct IP address, enter it in that string.
4. If a change is made to the registry, restart the whole server to ensure the change takes effect.
