# Finding Orphaned GPO Folders with PowerShell

During years and years of working in AD occasionally the sysvol folders gets out of sync with the actual GPOs. The following script will return all folders in sysvol\policies that no long have a corresponding GPO. **Please be sure to backup folders before taking any action based on this**

```#Initial Source: https://4sysops.com/archives/find-orphaned-active-directory-gpos-in-the-sysvol-share-with-powershell/

function Get-OrphanedGPOs {

[CmdletBinding()]
param (
[parameter(Mandatory=\$true,ValueFromPipelineByPropertyName)]
[string]\$Domain
)
begin {
\$orphaned = @()
}
process {
Write-Verbose "Domain: \$Domain"
# Get GPOs and convert guid into same format as folders
\$gpos = Get-GPO -All -Domain \$domain | Select @{ n='GUID'; e = {'{' + \$_.Id.ToString().ToUpper() + '}'}}| Select -ExpandProperty GUID
Write-Verbose "GPOs: \$(\$gpos | Measure-Object | Select -ExpandProperty Count)"

# Get GPOs policy folder
\$polPath = "\\\$domain\SYSVOL\\$domain\Policies\"
Write-Verbose "Policy Path: \$polPath"

# Get all folders in the policy path
\$folders = Get-ChildItem \$polPath -Exclude 'PolicyDefinitions'
Write-Verbose "Folders: \$(\$folders | Measure-Object | SElect -ExpandProperty Count)"

#compare and return only the Folders that exist without a GPO
\$gpoArray = \$gpos.GUID
ForEach (\$folder in \$folders) {
if (-not \$gpos.contains(\$folder.Name)) {
\$orphaned += \$folder
}
}
Write-Verbose "Orphaned: \$(\$orphaned | Measure-Object | SElect -ExpandProperty Count)"
return \$orphaned
}
end {
}

}
