How to Query remote PC's registry by OU for 2 values and export to CSV file.

Question

I'm new to scripting and to Powershell but this is what I have managed to put together so far. Of course it fails. We have two custom entries in the registry that I want to query remote workstations for these values, Monitor 1 and Monitor 2. Output to a
CSV along with the workstations name. Because of our AD structure I figured its just easier to input the OU individually as seen in the script. That portion of the script seems to work. I get the following error in bold when I run the script: I've Google'd
and tinkered with this for a week now with no resolution and seem to be going in circles.  And yes, I had help to get this far.

# 1) Searches Active Directory for all Computers under said OU

$SearchPath = "OU=XXX,OU=XXX,OU=XXX,DC=XXX,DC=XXX,DC=XXX"
$objSearcher = New-Object System.DirectoryServices.DirectorySearcher
$objSearcher.SearchRoot = New-Object System.DirectoryServices.DirectoryEntry("LDAP://$SearchPATH")
$objSearcher.PageSize = 1000
$objSearcher.Filter = "(objectClass=computer)"
$objSearcher.SearchScope = "Subtree"
$colProplist = "name"
$colResults = $objSearcher.FindAll()
$Store = @()
$Hive = [Microsoft.Win32.RegistryHive]"LocalMachine";
foreach ($result in $colResults)
# Use $result.properties.name to retreive ComputerName
$obj = New-Object PsObject
$obj | Add-member -type noteproperty -name "Computername" -Value $result.properties.name
$regKey = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey($Hive,$result.properties.name);
$ref = $regKey.OpenSubKey("SYSTEM\CurrentcontrolSet\control\Session Manager\Environment");
$obj | Add-member -type Noteproperty -name "Monitor1" -value $ref.OpenSubKey("Monitor")
$obj | Add-member -type Noteproperty -name "Monitor2" -value $ref.OpenSubKey("Monitor2")
$store += $obj
$store | Select-Object Computername,Monitor1,Monitor2 | Export-CSV -noTypeInformation -Path "Pathtosave.csv"
People are always promising the apocalypse. They never deliver.
Ok, I have modified the end of the script a bit, and no more error: Instead I get an unexpected output.
foreach ($result in $colResults)
    # Use $result.properties.name to retreive ComputerName
    $obj = New-Object PsObject
    $obj | Add-member -type noteproperty -name "Computername" -Value $result.properties.name
    $regKey = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey($Hive,$result.properties.name);
    $ref = $regKey.OpenSubKey("SYSTEM\CurrentcontrolSet\control\Session Manager\Environment");
    $obj | Add-member -type Noteproperty -name "Monitor1" -value $ref.OpenSubKey("Monitor")
    $obj | Add-member -type Noteproperty -name "Monitor2" -value $ref.OpenSubKey("Monitor2")
    $store += $obj
$store | Select-Object Computername,Monitor1,Monitor2 | Export-CSV -noTypeInformation -Path "C:\Utils\Data.csv"
Unexpected output:
"Computername","Monitor1","Monitor2"
"System.DirectoryServices.ResultPropertyValueCollection",,
"System.DirectoryServices.ResultPropertyValueCollection",,
"System.DirectoryServices.ResultPropertyValueCollection",,

Hi,
What do your registry values look like in the Monitor and Monitor2 subkeys?
EDIT: This might help:
# Retrieve list of computers using Get-ADComputer and process each
Get-ADComputer -Filter * -SearchBase 'OU=Test PCs,DC=domain,DC=com' | ForEach {
# Verify PC is alive
If (Test-Connection $_.Name -Quiet -Count 1) {
# Connect to registry
$remoteHive = [Microsoft.Win32.RegistryHive]“LocalMachine”;
$regKey = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey($remoteHive,$($_.Name))
# Open the Environment key
$ref = $regKey.OpenSubKey('SYSTEM\CurrentcontrolSet\control\Session Manager\Environment')
# Create an ordered hashtable with the data from string values named 'String Value One/Two' in Monitor and Monitor2 subkeys
# You'll need to adjust these values based on your actual data
# If you are running v2, remove [ordered] below (so the line reads $props = @{)
$props = [ordered]@{
Computer=$_.Name
Monitor =$ref.OpenSubKey('Monitor').GetValue('String Value One')
Monitor2=$ref.OpenSubKey('Monitor2').GetValue('String Value Two')
# Create a custom object based on the hashtable above
New-Object PsObject -Property $props
} | Sort-Object Computer | Export-Csv .\MonitorRegistryCheck.csv -NoTypeInformation
# The line above sorts the output object by the computer name and then exports the object to a CSV file
