Change fixed DNS setting via PSExec to deploy and run the PowerShell

Change fixed DNS setting via PSExec and PowerShell

1. Copy the "change_dns.ps1" to the target machine "C:\source\PSTools\change_dns\"

The "change_dns.ps1" content:

$dnsservers = "8.8.8.8"
$computers = Get-Content env:computername
foreach ($comp in $computers)
{

$adapters = gwmi -q "select * from win32_networkadapterconfiguration where ipenabled='true'" -ComputerName $comp
foreach ($adapter in $adapters)
{
  $adapter.setDNSServerSearchOrder($dnsservers)
}
 
}

2. PsExec command to run the PowerShell remotely:
(Copy the "change_dns.ps1" into the same folder of PSExec)

C:\source\PSTools\change_dns>PSExec \\Computer1 -u "admin" -p PASSWORD PowerShell -NoProfile -ExecutionPolicy Bypass C:\source\PSTools\change_dns\change_dns.ps1

If success, will return the following value:

PsExec v2.2 - Execute processes remotely
