Connect to SCCM Site with PowerShell

This script snippet can be used at the beginning of a script to dynamically find SCCM sites and then change directory to an SCCM CAS site, after which scripts can be run using SCCM cmdlets.

$PathToInstall = #YourPathHere
if (!(test-path ("C:\Program Files (x86)\ConfigMgrConsole\bin\ConfigurationManager.psd1")))
{
$Install = Read-host "No Configuration Manager commandlet installed. Would you like to install?[Y/N]"
    if ($Install -eq "Y")
    {
        #Install tools if desired
        start-process msiexec.exe -argumentlist "/i $PathToInstall /q" -Wait
    }
    else
    {
        #Exits script, as this won't work without SCCM module
        Write-host "No Commandlets found, exiting script"
        pause
        exit
    }

}
#Import modules for AD and SCCM from the start

# (optional) Dynamically retrieve the domain root distinguished name

# (optional) Get ADSI object to represent search root

$AdSearcher = [adsisearcher]"(objectClass=mSSMSSite)"

# (optional) Set search root of Active Directory searcher to System Management container
$AdSearcher.SearchRoot = $SearchRoot

# Make call to retrieve objects from Active Directory
$SccmSites = $AdSearcher.FindAll()

# Iterate over each mSSMSSite object, and give me the mssmssitecode property
# IMPORTANT: All Active Directory property references must be in lower-case, else ... fail
$SCCMSiteCodes = foreach ($SccmSite in $SccmSites)
{
