A customer wanted to change and validate the DNS configuration on a subnet so I created this script.

# Script that replaces or sets a random set of DNS servers on every networkadapter with a certain default gateway. # Version 1.0 # Created by: Lars Gustavsson Knowledge Factory # Creates two variables to randomly select between. $0 = "10.0.10.10,10.0.10.11" $1 = "10.0.10.11,10.0.10.10" #Getting the IP configuration on all interfaces with a manually configured gateway. $Interfaces = Get-NetIPConfiguration | Where-Object {$_.IPv4DefaultGateway.NextHop -eq "10.0.10.254" -and $_.IPv4Address.PrefixOrigin -eq "manual"} #Looping through all the interfaces and setting the DNS servers. foreach ($interface in $interfaces){ $DNS = Get-Random -InputObject $0, $1 Set-DnsClientServerAddress -InterfaceAlias $interface.InterfaceAlias -ServerAddresses $DNS } |
