<#
.SYNOPSIS This function creates a new Enterprise Subordinate/Intermediate/Issuing Certification Authority by either... A) Creating a brand new Windows Server VM; or B) Using an existing Windows Server on the network ...and then running a configuration script over a PS Remoting Session. Since this script needs to request a Certificate from the Root CA, in order to avoid the double-hop authentication issue, a one-time-use Scheduled Task is created, immediately run, and deleted immediately after completion. .DESCRIPTION See .SYNOPSIS .NOTES .PARAMETER CreateNewVMs This parameter is OPTIONAL. This parameter is a switch. If used, a new Windows 2016 Standard Server Virtual Machine will be deployed to the localhost. If Hyper-V is not installed, it will be installed (and you will need to reatart the localhost before proceeding). .PARAMETER VMStorageDirectory This parameter is OPTIONAL, but becomes MANDATORY if the -CreateNewVMs parameter is used. This parameter takes a string that represents the full path to a directory on a LOCAL drive that will contain all new VM files (configuration, vhd(x), etc.) .PARAMETER Windows2016VagrantBox This parameter is OPTIONAL, but becomes MANDATORY if the -CreateNewVMs parameter is used. This parameter takes a string that represents the name of a Vagrant Box that can be downloaded from https://app.vagrantup.com/boxes/search. Default value is "jborean93/WindowsServer2016". Another good Windows 2016 Server Vagrant Box is "StefanScherer/windows_2016". You can alternatively specify a Windows 2012 R2 Standard Server Vagrant Box if desired. .PARAMETER ExistingDomain This parameter is MANDATORY. This parameter takes a string that represents the name of the domain that the Subordinate CA will join. Example: alpha.lab .PARAMETER DomainAdminCredentials This parameter is MANDATORY. This parameter takes a PSCredential. The Domain Admin Credentials will be used to join the Subordinate CA Server to the domain as well as configre the new Subordinate CA. This means that the Domain Account provided to this parameter MUST be a member of the following Security Groups in Active Directory: - Domain Admins - Domain Users - Enterprise Admins - Group Policy Creator Owners - Schema Admins .PARAMETER PSRemotingCredentials This parameter is MANDATORY. This parameter takes a PSCredential. The credential provided to this parameter should correspond to a User Account that has permission to remote into the target Windows Server. If you're using a Vagrant Box (which is what will be deployed if you use the -CreateNewVMs switch), then the value for this parameter should be created via: $VagrantVMPassword = ConvertTo-SecureString 'vagrant' -AsPlainText -Force $VagrantVMAdminCreds = [pscredential]::new("vagrant",$VagrantVMPassword) .PARAMETER IPOfServerToBeSubCA This parameter is OPTIONAL, however, if you do NOT use the -CreateNewVMs parameter, this parameter becomes MANDATORY. This parameter takes a string that represents an IPv4 Address referring to an EXISTING Windows Server on the network that will become the new Subordinate CA. .PARAMETER IPofDomainController This parameter is OPTIONAL, however, if you cannot resolve the Domain Name provided to the -ExistingDomain parameter from the localhost, then this parameter becomes MANDATORY. This parameter takes a string that represents an IPv4 address referring to a Domain Controller (not readonly) on the domain specified by the -ExistingDomain parameter. .PARAMETER IPOfRootCA This parameter is MANDATORY. This parameter takes a string that represents an IPv4 address referring to the Root CA on the domain specified by the -ExistingDomain parameter. .PARAMETER PrimaryHyperVHostIPOverride This parameter is OPTIONAL. This parameter takes a string that represents an IPv4 Address that you would like to use as your External Netowrk on your Hyper-V host. .PARAMETER SkipHyperVInstallCheck This parameter is OPTIONAL. This parameter is a switch. If used, this function will not check to make sure Hyper-V is installed on the localhost. .EXAMPLE # Open an elevated PowerShell Session, import the module, and - PS C:\Users\zeroadmin> $VagrantVMPassword = ConvertTo-SecureString 'vagrant' -AsPlainText -Force PS C:\Users\zeroadmin> $VagrantVMAdminCreds = [pscredential]::new("vagrant",$VagrantVMPassword) PS C:\Users\zeroadmin> $DomainAdminCreds = [pscredential]::new("alpha\alphaadmin",$(Read-Host 'Enter Passsword' -AsSecureString)) Enter Passsword: ************ PS C:\Users\zeroadmin> $CreateSubCASplatParams = @{ >> CreateNewVMs = $True >> VMStorageDirectory = "H:\VirtualMachines" >> ExistingDomain = "alpha.lab" >> IPOfDomainController = "192.168.2.112" >> IPOfRootCA = "192.168.2.113" >> PSRemotingCredentials = $VagrantVMAdminCreds >> DomainAdminCredentials = $DomainAdminCreds >> } PS C:\Users\zeroadmin> $CreateSubCAResult = Create-SubordinateCA @CreateSubCASplatParams #> function Create-SubordinateCA { [CmdletBinding()] Param ( [Parameter(Mandatory=$False)] [switch]$CreateNewVMs, [Parameter(Mandatory=$False)] [string]$VMStorageDirectory, [Parameter(Mandatory=$False)] [string]$Windows2016VagrantBox = "jborean93/WindowsServer2016", # Alternate - StefanScherer/windows_2016 [Parameter(Mandatory=$True)] [ValidatePattern("^([a-z0-9]+(-[a-z0-9]+)*\.)+([a-z]){2,}$")] [string]$ExistingDomain, [Parameter(Mandatory=$True)] [pscredential]$DomainAdminCredentials, [Parameter(Mandatory=$True)] [pscredential]$PSRemotingCredentials, [Parameter(Mandatory=$False)] [string]$IPofServerToBeSubCA, [Parameter(Mandatory=$False)] [string]$IPofDomainController, [Parameter(Mandatory=$True)] [string]$IPofRootCA, [Parameter(Mandatory=$False)] [string]$PrimaryHyperVHostIPOverride, [Parameter(Mandatory=$False)] [switch]$SkipHyperVInstallCheck ) #region >> Helper Functions # TestIsValidIPAddress # ResolveHost # GetDomainController # Deploy-HyperVVagrantBoxManually # Get-VagrantBoxManualDownload # New-SubordinateCA #endregion >> Helper Functions #region >> Prep $StartTime = Get-Date $ElevationCheck = [System.Security.Principal.WindowsPrincipal]::new([System.Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([System.Security.Principal.WindowsBuiltInRole]::Administrator) if (!$ElevationCheck) { Write-Error "You must run the build.ps1 as an Administrator (i.e. elevated PowerShell Session)!
