Hello everyone,

I have one powershell script. https://itdungeon.blogspot.com/2021/11/update-dns-static-servers-in-your-local.html

$inet1=Get-DnsClient | Get-DnsClientServerAddress | where{$.ServerAddresses -contains "192.168.0.245" -or $.ServerAddresses -contains "192.168.0.207"}
foreach($nic in $inet1){
Set-DnsClientServerAddress -InterfaceIndex $nic.InterfaceIndex -ServerAddresses ("192.168.0.245","192.168.0.114")

    Hi,

    If I understand your question , you want add confirmation for each NIC modification.
    Below a Example : 

    $inet1=Get-DnsClient | Get-DnsClientServerAddress | where{$_.ServerAddresses -contains "192.168.0.245" -or $_.ServerAddresses -contains "192.168.0.207"}

foreach($nic in $inet1){

$interfaceAlias = $nic.InterfaceAlias
$yes = Read-Host -Prompt "type Yes to confirm the modification on $interfaceAlias :"

if($yes -eq "Yes"){
Set-DnsClientServerAddress -InterfaceIndex $nic.InterfaceIndex -ServerAddresses ("192.168.0.245","192.168.0.114")
}
}

    Please don't forget to mark helpful reply as answer

    Before you run your script, run this: 

    Get-ExecutionPolicy -List  
  
  
        Scope ExecutionPolicy  
        ----- ---------------  
MachinePolicy       Undefined  
   UserPolicy       Undefined  
      Process    RemoteSigned  
  CurrentUser       Undefined  
 LocalMachine    RemoteSigned

    There is nothing in that script that changes the execution policy. Are you seeing that warning when you start a PowerShell session (before you run anything)? If you do, it's because there's something in the PowerShell profile that trying to change it.

    Also check the $Profile variable when you start the session with "run as administrator" and when you start a session as an unprivileged user.

    Have a look at this, too: about_profiles

    I've found this script

    Get-WmiObject -Class Win32_NetworkAdapterConfiguration -Filter IPEnabled=TRUE | Where-Object {!$.DHCPEnabled} | ForEach-Object { $.SetDNSServerSearchOrder('8.8.8.8','8.8.8.4')}

    https://learn.microsoft.com/en-us/answers/questions/174234/how-to-add-dns-record-only-to-computers-with-stati.html

    It's a great script. But when I clicked appear this error:

    annot find an overload for "SetDNSServerSearchOrder" and the argument count: "2".
    At C:\Users\Administrator\Desktop\dns12.ps1:1 char:131

    • ... rEach-Object { $_.SetDNSServerSearchOrder('8.8.8.8','8.8.8.4')}
    • ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    • CategoryInfo : NotSpecified: (:) [], MethodException
    • FullyQualifiedErrorId : MethodCountCouldNotFindBest

    But when I type one DNS ip, process is done. How can I solve?

    You can't have the execution policy in the script.

    You set this outside the script. If this is running from a server, its usually dictated by some sort of group policy for that server. As its not feasible to have to set the execution policy each and every time.

    I have policies that allow unrestricted access, but only from a certain number of dev machines and the integration server that runs scripts. (But your scripts really should be signed).

    If you can't set\force the execution policy, its probably down to rights and policy, which you will need to speak to your administrators about.

    Certain organisations will block unsigned scripts from running or only allow from certain workstations.
