  1. Start the DNS Management MMC snap-in (Start - Programs - Administrative Tools - DNS Management)
  2. Expand the server, expand Forward Lookup Zones and select "."
  3. Right click and select Delete
  4. Click Yes to the confirmation
  5. Stop and Start the DNS manager and the tabs are available
