RDP Connection Error: No Remote Desktop Client Access Licenses Available

So, as of recent I have had several occurrences of this wonderful RDP error as of late, so I figured I'd share what I've found to be helpful. It pops up upon connection and goes like this: "Remote session was disconnected because there are no Remote Desktop client access licenses available for this computer. Please contact the server administrator." And it looks something like this:



Oddly enough this type of error has noting to do with licensing, it's typically the cause of a bad Registry Key. But before we go Registry diving, I suggest attempting to rebuild the default RDP profile. This may work in some cases, but more than likely, you will be following the later steps. To remove the "Default.rdp" file:

  1. Open File Explorer
  2. Navigate to Documents
  3. Locate "Default.rdp" and Delete it


Attempt to launch an RDP session. If that fixes your error than you'r done. If not, follow these next steps to remove the Registry Key that's causing the issue.
  1. Click the Start button and in the search bar type Regedit.exe
  2. Navigate to the following registry key:
    1. HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSLicensing
  3. Delete the key
  4. Attempt to reconnect to the remote PC
If it doesn't work than you will get the following error message: “The remote computer disconnected the session because of an error in the licensing protocol“;

Then all you need to do is Right-Click on the Remote Desktop Connection icon and select "Run as Administrator".

PowerShell Scripting: Low Disk Space Notification

Update 20150812 You'll see in the below comments that I left a global variable that was not required in the original script. The below post has been updated with that variable removed. Original Post So, I came across a need to have a script that checks the free space of a hard drive, calculates the percentage and send an e-mail notification of the free space is less than 10%. I figured that this could be scripted with PowerShell and run as a scheduled task in Windows. One thing I did find out is that I needed to create a service account in Active Directory with Server Admin permissions. Once you have that account in place simply copy the script below and name it "WhatYouWant.ps1" and set your Windows task accordingly. Disclaimer: I did reach out for assistance with creating this script on StackOverflow. My original script was writing the output to a text file, and copying the contents of that text file into the e-mail notification. This was not acceptable for the long...

PowerShell Scripting: Removing Multiple Directories

Update 20150916 So the pic I used to display the CSV sample went missing. So the latest update just includes a text version of what was displayed. Thanks! Original Post I'm still fairly new to utilizing PowerShell to automate tasks and get big tasks done. But every time I use it, the tool makes my life a whole lot easier. Recently I was tasked with deleting over 500 directories. Thankfully someone else had the task of identifying the directories that were slated to be deleted, I just had to complete the process of removing them. Thanks to a little article from the Scripting Guy! Blog (found HERE ) I had some direction to start in. What I ended up doing is creating a single column CSV file that contains the path to the directories to be deleted. This path includes drive letter, and the overall path to the folder. It should look similar to this: delete C:\Path\to\folder C:\Path\to\folder2 D:\Path\to\folder D:\Path\to\folder2 I named the file "delete.csv" and pla...

Using Python for GPG/PGP File Encryption - Part 1

So, this will be the start of a series that will build a python script for GPG/PGP file encryption. In this post, we'll look at installing gnupg for python and using python to setup the keystore, create a private key, exporting the associated public key, and importing a public key. Now everything done here can be done with simple gnupg commands, but learning how to do this with python will help in understanding the script we'll be building to complete file encryption. I will be covering non-python gnupg commands in a future post. Additionally, the folks at the python-gnupg site over at pythonhosted.org have done a really great job at documenting everything (link to their site at the bottom). The stuff I'll be going over will be more of a start-to-finish for anyone that may get lost in the muck of doing stuff with python. Full Disclosure #1: Any key identifier throughout the series of posts is FICTITIOUS and DOES NOT represent any real key, either associated with myself or...
