Failed while adding virtual Ethernet switch

Well you know bad things happen right before you make a presentation.  I have no idea how this happened.  Tomorrow I am presenting PowerShell Desired State Configuration to my Advanced PowerShell class.  I’m going through a test run of my code and I lose my external internet connection in my VMs.  I am unable to create a new external VM switch connected to my wireless NIC on my Windows 10 Pro client.  Here is my error:

Failed while adding virtual Ethernet switch connections. Ethernet Port (long guid) bind failed: Catastrophic failure (0x8000FFFF)

Not funny!!!!!  I went through a lot of documentation which did not work.  Here is my final solution. 

Open the Network and Sharing Center
Click Change Adapter Settings
Open the properties of your wireless network adapter.
Click the Sharing tab.
Check Allow other network and users to connect through this computer’s Internet Connection.
Click OK.
Open the properties of your wireless network adapter.
Click the Sharing tab.
Uncheck Allow other network and users to connect through this computer’s Internet Connection.
Now go ahead and create you external VM Switch in Hyper-V

Adding a Comment to a GPO with PowerShell

As I'm writing this article, I'm also writing a customization for a PowerShell course I'm teaching next week in Phoenix.  This customization deals with Group Policy and PowerShell.  For those of you who attend my classes may already know this, but I sit their and try to ask the questions to myself that others may ask as I present the material.  I finished up my customization a few hours ago and then I realized that I did not add in how to put a comment on a GPO.  This is a feature that many Group Policy Administrators may not be aware of. This past summer I attended a presentation at TechEd on Group Policy.  One organization in the crowd had over 5,000 Group Policies.  In an environment like that, the comment section can be priceless.  I always like to write in the comment section why I created the policy so I know its purpose next week after I've completed 50 other tasks and can't remember what I did 5 minutes ago. In the Group Policy module for PowerShell V3, th

Return duplicate values from a collection with PowerShell

If you have a collection of objects and you want to remove any duplicate items, it is fairly simple. # Create a collection with duplicate values $Set1 = 1 , 1 , 2 , 2 , 3 , 4 , 5 , 6 , 7 , 1 , 2   # Remove the duplicate values. $Set1 | Select-Object -Unique 1 2 3 4 5 6 7 What if you want only the duplicate values and nothing else? # Create a collection with duplicate values $Set1 = 1 , 1 , 2 , 2 , 3 , 4 , 5 , 6 , 7 , 1 , 2   #Create a second collection with duplicate values removed. $Set2 = $Set1 | Select-Object -Unique   # Return only the duplicate values. ( Compare-Object -ReferenceObject $Set2 -DifferenceObject $Set1 ) . InputObject | Select-Object – Unique 1 2 This works with objects as well as numbers.  The first command creates a collection with 2 duplicates of both 1 and 2.   The second command creates another collection with the duplicates filtered out.  The Compare-Object cmdlet will first find items that are diffe
