    Hi,

    I am looking for a simpler way to update the DNS CNAME by using PowerShell script. We are planning to use this scenario for changing the connection string in the powerBI report server. By changing the CNAME we can point to other server.

    I also need to understand what are the prerequisite to achieve it. I already have the full control for the that CNAME Record. DO we need some other permission. I think we require permission to the DNS server or there is any other way to access the DNS. I am asking this because it is a highly protected environment. 

    Regards
    Rajaniesh

    Hi,

    You have to delete the cname first and then recreate it.

    $zone = "mydomain.com"
$name = "myhost"
$cname ="mycname"
$DNSServer = "mydnsserver.mydomain.com"

Remove-DnsServerResourceRecord -Name $name -ZoneName $zone -RRType CName -ComputerName $DNSServer -Force
Add-DnsServerResourceRecordCName -Name $name -ZoneName $zone -HostNameAlias $cname -ComputerName $DNSServer

    You would need permissions to create the record as well. Once you've created its, you're the owner of it and can delete its again.
