Powershell to update DNS SOA & TTL modification?

[IT Engineer]

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.
