Create an AD Drive for Specified Domain

When you load the Active Directory Module, you get, by default, an Active Directory PSDrive for the current domain.   You can avoid the drive from loading by setting $Env:ADPS_LoadDefaultDrive = 0. When writing scripts to export and import AD delegations, connecting to this remote drive became important to me. Here is an example of the code I used:

#Requires -module ActiveDirectory
#Ensure the AD drive is available
if ($Env:ADPS_LoadDefaultDrive -eq 0){
Remove-Module activedirectory -Force;
$Env:ADPS_LoadDefaultDrive = 1
}

Import-Module activedirectory -NoClobber

Function Create-RemoteADDrive{
    Param
    (
        # DNS name of domain to connect to
        [Parameter(Mandatory=$true,Position=0)] $DNSDomain,
        [Switch]$ConnectToRoot
    )

    #Remove drive if it exists
    if (Test-Path RemoteAD:){    SL c: ;   Remove-PSDrive RemoteAD  }
        $RemoteDomain = Get-ADDomain $DNSDomain
        $server = ($RemoteDomain).RidMaster
        if ($ConnectToRoot){
        $Root = ''
    }ELSE{
        #Connect to Default Naming Context
        $Root = ($RemoteDomain).DistinguishedName
    }
    #Note Scope is Script.  If not set, disappears outside of function.  Can set to Global
    New-PSDrive -Name "RemoteAD" -PSProvider ActiveDirectory -root $Root -server $server -Scope Script
}
#Example Create remote drive called RemoteAD for the default naming context of constoso.com, and change to that drive.
Create-RemoteADDrive 'Contoso.com'
SL RemoteAD:
