      Hi All,

      I need some help in modifying this below Powershell to add DNS server entry from a list of domains and setup the SOA TTL into 15 minutes.

      So far I cannot figure it out how to:

      1. Set the SOA TTL to just 15 minutes.
      2. set the SOA number to be YYYYMMddd01

      $DomainNames = 'CorporateProduct1.com'
      $PrimaryDNSServer = 'PRDSVRDNS01-VM'
      $SecondaryDNSServer1 = 'PRDSVRDNS02-VM'
      $SecondaryDNSServer2 = 'PRDSVRDNS03-VM'
      #Create Primary DNS Forward Lookup Zone
      Add-DnsServerPrimaryZone -ComputerName $PrimaryDNSServer -Name $DomainNames -ZoneFile $DomainNames.dns -DynamicUpdate None -ResponsiblePerson "domains.$($ENV:USERDNSDOMAIN.ToLower())"
      Set-DnsServerPrimaryZone -ComputerName $PrimaryDNSServer -Name $DomainNames -SecureSecondaries "TransferToSecureServers" -SecondaryServers "$([System.Net.Dns]::GetHostAddresses($SecondaryDNSServer1).IPAddressToString)", "$([System.Net.Dns]::GetHostAddresses($SecondaryDNSServer2).IPAddressToString)"
      # Set the Public DNS servers to replicate to
      Add-DnsServerResourceRecord -ComputerName $PrimaryDNSServer -Name '@' -ZoneName $DomainNames -NS -NameServer "ns1.$ENV:USERDNSDOMAIN"
      Add-DnsServerResourceRecord -ComputerName $PrimaryDNSServer -Name '@' -ZoneName $DomainNames -NS -NameServer "ns2.$ENV:USERDNSDOMAIN"
      Add-DnsServerResourceRecord -ComputerName $PrimaryDNSServer -Name '@' -ZoneName $DomainNames -NS -NameServer "ns3.$ENV:USERDNSDOMAIN"
      #Let the Forward lookup zones created completely
      Start-Sleep -Seconds 5
      #Replicate the Forwardlookup zones into two additional Public DNS servers
      Add-DnsServerSecondaryZone -ComputerName $SecondaryDNSServer1 -MasterServers [System.Net.Dns]::GetHostAddresses($PrimaryDNSServer).IPAddressToString -Name $DomainNames -ZoneFile "$DomainNames.dns"
      Add-DnsServerSecondaryZone -ComputerName $SecondaryDNSServer2 -MasterServers [System.Net.Dns]::GetHostAddresses($PrimaryDNSServer).IPAddressToString -Name $DomainNames -ZoneFile "$DomainNames.dns"

      I’m also not sure if @Splatting is even worked on the above query, hence I am asking it here.

      Thank you in advance.
