Pointer Record

Question

Hi All

i have a csv file in the below format
HostName IP
Server01 192.168.5.10
Server02 192.168..5.11

Please guide me how to create pointer records using powershell.
for example i have Reverse Lookup Zone 5.168.192.in.addr.arpa. i want to create a pointer record for the server server01 pointing to 192.168.5.10
if the reverse lookup zone 5.168.192.in.addr.arpa doesn't exist then reverse lookup zone should be created.

i want to try the below script but not sure. please guide me.

$ServerName = "MYDC01"
$domain = "contoso.com"
import-csv C:\srv.csv | ForEach-Object {
$Computer = "$($.HostName).$domain"
$addr = $.IP -split "."
$RLZ = "${$addr[1]}.${$addr[0]}.in-addr.arpa"
dnscmd $Servername /zoneadd $RLZ /primary
dnscmd $Servername /recordadd $rzone "${$addr[3]}.${$addr[2]}" PTR $HostName
}

Hi，

As RichMatheisen-8856 pointed out above, if the DNS server is "MYDC01" and you run the script on "JumpServer01", you could specify the DNS server with the "-ComputerName" parameter.

$ServerName = "MYDC01"  
$domain = "contoso.com"  
import-csv C:\srv.csv | ForEach-Object {  
    $Computer = "$($_.HostName).$domain"  
    $addr = $_.IP -split "\."  
    $RLZ = "$($addr[2]).$($addr[1]).$($addr[0]).in-addr.arpa"  
    if($RLZ -notin (Get-DnsServerZone -ComputerName $ServerName).ZoneName){  
        Add-DnsServerPrimaryZone -Name $RLZ -ReplicationScope Forest -ComputerName $ServerName  
    }  
    Add-DnsServerResourceRecordPtr -Name "$($addr[3])" -ZoneName $RLZ -PtrDomainName $Computer -ComputerName $ServerName  
}

Hi，

Please check to see if this works.

$ServerName = "MYDC01"  
$domain = "contoso.com"  
import-csv C:\srv.csv | ForEach-Object {  
    $Computer = "$($_.HostName).$domain"  
    $addr = $_.IP -split "\."  
    $RLZ = "$($addr[2]).$($addr[1]).$($addr[0]).in-addr.arpa"  
    if($RLZ -notin (Get-DnsServerZone).ZoneName){  
        Add-DnsServerPrimaryZone -Name $RLZ -ReplicationScope Forest  
    }  
    Add-DnsServerResourceRecordPtr -Name "$($addr[3])" -ZoneName $RLZ -PtrDomainName $Computer  
}

I am getting below error
i have selected $ServerName = "MYDC01" in the error log i am seeing JumpServer01 as i am logged in to jumpserver01 and executing this syntax. i have domain admin rights.

Get-DnsServerZone : Failed to enumerate zones from the server JumpServer01.

Answer 4

If the DNS server is on the machine "MYDC01" the you'll have to add "-ComputerName $ServerName" to the Get-DnsServerZone and Add-DnsServerResourceRecordPtr cmdlets.

Answer 5

i am not clear how to add in the syntax
