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

Code: [Select all] [Expand/Collapse] [Download] (Untitled.ps1)

$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 for some assistance.

Thank you in advance.

That is because there is no splatting in this code.

OK, how about making it work first before splitting it.

hence using the below one lines:

Get-DnsServerResourceRecord -ComputerName $PrimaryDNSServer -ZoneName $DomainNames -RRType Soa | Format-List

How can I incorporate the below lines:

Code: Select all

$old = $new = ""
$old = Get-DnsServerResourceRecord -ComputerName $PrimaryDNSServer -ZoneName $DomainNames -Name "@" -RRType SOA
$new = $old.Clone()
#$new.RecordData.SerialNumber = (Get-Date -Format 'yyyyMMdd01').ToString()
$new.RecordData = "[$((Get-Date -Format 'yyyyMMdd01').ToString())][ns1.$ENV:USERDNSDOMAIN.][domains.$($ENV:USERDNSDOMAIN.ToLower()).][1.00:00:00][01:00:00][00:15:00][00:10:00]"
$new.TimeToLive = 00:15:00
Set-DnsServerResourceRecord -ComputerName $PrimaryDNSServer -ZoneName $DomainNames -OldInputObject $old -NewInputObject $new
