Finding a DNS Zone Creation Date

Not SCOM related, but this is pretty much the only place I dump things I need to remember, and maybe you'll find it useful.

Was in my Windows Server DNS console this morning and I noticed some odd domains listed. I don't remember seeing them before and wanted to see when they were created, to make sure folks weren't randomly adding new zones.

  • Fire up adsiedit.msc on a domain controller.
  • Choose Connect to
  • Under Connection Point, choose Select or type a Distinguished Name or Naming Context
  • Enter DC=DomainDnsZones,DC=<second level DNS>,DC=<top level DNS>
    • E.G. dc=DomainDnsZones,DC=contoso,DC=corp
  • Next, select CN=MicrosoftDNS
  • In the right hand pane, look for the zone in question, reverse or forward
  • Right-click on the folder and select Properties
  • Browse to the whenCreated properties to find out when the zone was added to the system
