function Install-DCChildDomain { <# .SYNOPSIS Installs a child domain. .DESCRIPTION Installs a child domain. .PARAMETER ComputerName The server to promote to a DC hosting a new subdomain. .PARAMETER Credential The credentials to use for connecting to the DC-to-be. .PARAMETER DomainName The name of the domain to install. Note: Only specify the first DNS element, not the full fqdn of the domain. (The component usually representing the Netbios Name) .PARAMETER ParentDomainName The FQDN of the parent domain. .PARAMETER NetBiosName The NetBios name of the domain. Will use the DomainName if not specified. .PARAMETER SafeModeAdministratorPassword The SafeModeAdministratorPassword specified during domain creation. If not specified, a random password will be chosen. The password is part of the return values. .PARAMETER EnterpriseAdminCredential The Credentials of an Enterprise administrator. Will prompt for credentials if not specified. .PARAMETER NoDNS Disables installation and configuration of the DNS role as part of the installation. .PARAMETER NoReboot Prevents reboot of the server after installation. Note: Generally a reboot is required before proceeding, disabling this will lead to having to manually reboot the computer. .PARAMETER LogPath The path where the NTDS logs should be stored. .PARAMETER Sysvolpath The path where SYSVOL should be stored. .PARAMETER DatabasePath The path where the NTDS database is being stored. .PARAMETER NoResultCache Disables caching of the command's return object. By default, this command will cache the return object as a global variable. .PARAMETER EnableException This parameters disables user-friendly warnings and enables the throwing of exceptions. This is less user friendly, but allows catching exceptions in calling scripts. .PARAMETER Confirm If this switch is enabled, you will be prompted for confirmation before executing any operations that change state. .PARAMETER WhatIf If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run. .EXAMPLE PS C:\> Install-DCChildDomain -ComputerName 10.1.2.3 -Credential $cred -DomainName corp -ParentDomainName contoso.com Will install the childdomain corp.contoso.com under the domain contoso.com on the server 10.1.2.3. #> [Diagnostics.CodeAnalysis.SuppressMessageAttribute("PSAvoidGlobalVars", "")] [Diagnostics.CodeAnalysis.SuppressMessageAttribute("PSUseDeclaredVarsMoreThanAssignments", "")] [Diagnostics.CodeAnalysis.SuppressMessageAttribute("PSUseShouldProcessForStateChangingFunctions", "")] [Diagnostics.CodeAnalysis.SuppressMessageAttribute("PSReviewUnusedParameter", "")] [CmdletBinding(SupportsShouldProcess = $true)] Param ( [PSFComputer] $ComputerName = 'localhost', [PSCredential] $Credential, [Parameter(Mandatory = $true)] [PsfValidatePattern('^([a-zA-Z0-9]|[a-zA-Z0-9][a-zA-Z0-9\-_]{0,61}[a-zA-Z0-9])$', ErrorString = 'DCManagement.Validate.Child.DomainName')] [string] $DomainName, [Parameter(Mandatory = $true)] [PsfValidatePattern('^([a-zA-Z0-9]|[a-zA-Z0-9][a-zA-Z0-9\-_]{0,61}[a-zA-Z0-9])(\.([a-zA-Z0-9]|[a-zA-Z0-9][a-zA-Z0-9\-_]{0,61}[a-zA-Z0-9])){1,}$', ErrorString = 'DCManagement.Validate.Parent.DnsDomainName')] [string] $ParentDomainName, [string] $NetBiosName, [securestring] $SafeModeAdministratorPassword = (New-Password -Length 32 -AsSecureString), [PSCredential] $EnterpriseAdminCredential = (Get-Credential -Message "Enter credentials for Enterprise Administrator to create child domain"), [switch] $NoDNS = (Get-PSFConfigValue -FullName 'DCManagement.Defaults.NoDNS'), [switch] $NoReboot = (Get-PSFConfigValue -FullName 'DCManagement.Defaults.NoReboot'), [string] $LogPath = (Get-PSFConfigValue -FullName 'DCManagement.Defaults.LogPath'), [string] $Sysvolpath = (Get-PSFConfigValue -FullName 'DCManagement.Defaults.SysvolPath'), [string] $DatabasePath = (Get-PSFConfigValue -FullName 'DCManagement.Defaults.DatabasePath'), [switch] $NoResultCache, [switch] $EnableException ) begin { #region Scriptblock $scriptBlock = { param ($Configuration) function New-Result { [CmdletBinding()] param ( [ValidateSet('Success', 'Error')] [string] $Status = 'Success', [string] $Message, $ErrorRecord, $Data ) [PSCustomObject]@{ Status = $Status Success = $Status -eq 'Success' Message = $Message Error = $ErrorRecord Data = $Data SafeModeAdminPassword = $null } } #
