New appliances may not be able to resolve host names using DNS. This is because the local DNS server has itself configured as a root zone.

In order for DNS operations on the appliance to return to normal, the root zone must be deleted.

1. Go to the Appliance Desktop.
   
2. Go to Start -> Programs -> Administrative Tools -> DNS
   
3. Drill down to the Forward Zones folder in the DNS Server Administration Utility.
   
4. If there is a folder present named """"."""" , then delete it.
   
5. Restart the DNS Server service.

DNS operations will return to normal at that point
