Script to Change DNS Servers on Remote Server

Question

I am new to powershell and I am trying to construct a script to change the DNS servers settings on a whole list of machines remotely. I have the list of machines that I want to change in a txt file. I have read several posts on this and tried several different
methods but I cannot seem to get it to work. Here is my code, any help is much appreciated.
$servers = Get-Content C:\PathToFile\computers.txt
foreach($server in $servers)
    Write-Host "Connect to $server..."
    $nics = Get-WmiObject Win32_NetworkAdapterConfiguration -ComputerName $server -ErrorAction Inquire | Where{$_.IPEnabled -eq "TRUE"}
    $newDNS = "10.1.1.1","10.2.2.2"
    foreach($nic in $nics)
        Write-Host "`tExisting DNS Servers " $nic.DNSServerSearchOrder
        $x = $nic.SetDNSServerSearchOrder($newDNS)
        if($x.ReturnValue -eq 0)
            Write-Host "`tSuccessfully Changed DNS Servers on " $server
        else
            Write-Host "`tFailed to Change DNS Servers on " $server

Ed Wilsons Blog.
$computer = Get-Content C:\PathToFile\computers.txt
$wmi = Get-WmiObject win32_networkadapterconfiguration  -computername "$computer" -filter "ipenabled = 'true'"
$wmi.SetDNSServerSearchOrder("10.0.0.15", "255.255.255.0")
I dont have the feasibility to check as of now. Please test and let me know.
Thanks
