How to speed up the time out process in PowerShell

While executing scripts against a large number of clients in your organization, you will undoubtedly encounter a few that are offline.  This causes your script to hang on each one.  This pesky little behavior can be mitigated in a variety of ways.  The function below is what I use when I need to run a script synchronously.  You simple give it the name of the client you are attempting to contact and the number of retries it gets.  I usually only give it 1.  It will return TRUE if contact was made.  You then make a decision of what to do at that point. I allow the script to proceed if the response is TRUE or I send the client name to an error log if it is FALSE.
Function Test-ClientConnectivity
{
Param (
    $ComputerName,
    $Loop = 4)

    # Set the control value to zero.
    $Count = 0
    Do {
        $Count ++
        $Result = Test-Connection $ComputerName -Count 1 -Quiet
        If ($Result)
        {
            # If a positive responce is recieved, set the value
            # high to exit the loop.
            $Count = 1000000
        }

    } while ($Count -lt $Loop)

    # Return the object to the calling statment.
    Write-Output $Result
} # End Function: Test-CliectConnectivity -------------------------------------

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
