Rule Text

Remote Desktop Services is not configured to delete temporary folders.

Description

Discussion Text

This setting controls the deletion of the temporary folders when the session is terminated. Temporary folders should always be deleted after a session is over to prevent hard disk clutter and potential leakage of information.

Assessment Script Powered by AISyntax-verified

A standalone PowerShell script to assess this control automatically. Review before running it in your environment.

Syntax-checked as valid PowerShell. Not executed here — running it for real needs the actual windows_7 target this check assesses.

# oval:mil.disa.fso.windows:def:3868
$compliant = Test-Path -Path "HKLM:\Software\Policies\Microsoft\Windows NT\Terminal Services\DeleteTempDirsOnExit" -and ((Get-ItemProperty -Path "HKLM:\Software\Policies\Microsoft\Windows NT\Terminal Services").DeleteTempDirsOnExit -eq 1)
if ($compliant) { Write-Output "PASS"; Exit 0 } else { Write-Output "FAIL"; Exit 1 }

Remediation

Configure the policy value for Computer Configuration -> Administrative Templates -> Windows Components -> Remote Desktop Services -> Remote Desktop Session Host -> Temporary Folders “Do not delete temp folder upon exit” to “Disabled”.
