As per the title, find the DNS addresses from a text list of servers:
#Get the DNS for a List of Servers
#Get the admin permissions
$LoginPassword = Get-Credential
#Get the list of computers from a text file
$computer = get-content C:\temp\servers.txt
#Get the DNS IP's using the get-wmiobject (using wmi as some servers dont have powershell installed)
$NICs = Get-WMIObject Win32_NetworkAdapterConfiguration -computername $computer -Credential $LoginPassword |where{$_.IPEnabled -eq “TRUE”}
# for each server list the current setting
Foreach($NIC in $NICs) {
Write-Host "DNS Servers:"
$NIC.DNSHostName
$NIC.DNSServerSearchOrder
}
