Powershell Script to set DNS Servers

Your DNS servers have changed.  Your servers have statically set IP addresses and you need to update the DNS entries.  You have a bunch of servers and don't want to do this manually.  This script will run through a text file that you created with all your servers in it.

Assumptions:  You have a file called servers.txt that contains a list of your servers (one on each line).

Copy the text below and paste into a text editor.
Change the line $DNSServers and put in the addresses you want.
Save the file as:  SetDNS.ps1
Open up a powershell window and run.
Check your servers DNS settings to confirm.

$computer = get-content C:\misc\servers.txt $NICs = Get-WMIObject Win32_NetworkAdapterConfiguration -computername $computer |where{$_.IPEnabled -eq “TRUE”} Foreach($NIC in $NICs) { $DNSServers = "192.168.1.1","192.168.1.2" $NIC.SetDNSServerSearchOrder($DNSServers) $NIC.SetDynamicDNSRegistration(“TRUE”) }
