After long vacation, celebrated christmas and new year, like most of people I have to go back to work. I’ve checked my emails and check some servers using Remote Desktop Manager. However when I needed to login to Azure Portal, I have to re-enter my credentials.. hmm. Looked at my one note (secure password 🙂 but the password seems to be not working. Went back to RDP Manager, however the password can’t be shown as clear text. Time for google.. How to decrypt the password from Remote Desktop Manager.

By using powershell script below (thanks to this link), you’ll be able to retrieve the password from the Remote Desktop Manager.

# Path to RDCMan.exe
$RDCMan = “C:\Program Files (x86)\Microsoft\Remote Desktop Connection Manager\RDCMan.exe”
# Path to RDG file
$RDGFile = “{<>}”
$TempLocation = “C:\temp”

Copy-Item $RDCMan “$TempLocation\RDCMan.dll”
Import-Module “$TempLocation\RDCMan.dll”
$EncryptionSettings = New-Object -TypeName RdcMan.EncryptionSettings

$XML = New-Object -TypeName XML
$XML.Load($RDGFile)
$logonCredentials = Select-XML -Xml $XML -XPath ‘//logonCredentials’

$Credentials = New-Object System.Collections.Arraylist
$logonCredentials | foreach {
[void]$Credentials.Add([pscustomobject]@{
Username = $_.Node.userName
Password = $(Try{[RdcMan.Encryption]::DecryptString($_.Node.password, $EncryptionSettings)}Catch{$_.Exception.InnerException.Message})
Domain = $_.Node.domain
})
} | Sort Username

$Credentials | Sort Username
