(Mass) Modifying SOA record values by using Set-DnsServerResourceRecord

Today I wanted to update all serial numbers (to make sure that are written in YYYYMMDD00 way) on my primary DNS zones on my Windows server 2019 DNS server.

This is the script to do this massive change – by using this script anyone can modify any parameters in DNS.

$allzones = Get-DnsServerZone | Where-Object -Property ZoneType -EQ -Value “Primary”
foreach ($allzone in $allzones) {
$old = “”
$new = “”
$old = Get-DnsServerResourceRecord -ZoneName $allzone.ZoneName -Name “@” -RRType Soa
$new = $old.Clone()
$new.RecordData.SerialNumber = 2019080400
Set-DnsServerResourceRecord -OldInputObject $old -NewInputObject $new -ZoneName $allzone.ZoneName -PassThru
}
