A PowerShell Desired State Configuration Script that configures a server with the DNS and DHCP roles, and configures said roles for a web farm.
Raw
SamplePushConfig.ps1
<#
Sample DSC Configuration for a DNS/DHCP Server
DNS is configured to house addresses for a server pool and a sql server
DHCP is configured for reservations to the server pool
Script was tested in a DSC push configuration.
Tested using Server 2012 R2 DC Core running PowerShell v4.
Server is not joined to a domain.
Test Server has two virtual network interfaces with one configured as "TestInt".
Before testing, please run the following on the test server:
winrm qc
winrm s winrm/config/client '@{TrustedHosts="*"}'
Also be sure to download the DSC Resource kit at:
https://github.com/PowerShell/xPSDesiredStateConfiguration
and install it at $env:programfiles\windowspowershell\modules.
Also, be sure to have KB2883200 installed.
DNS Record entries are created using Round Robin rotation.
