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 -------------------------------------

How to run GPResult on a remote client with PowerShell

Where did a User’s Account Get Locked Out?

Updated: May 15, 2015 When this article was originally published, two extra carriage returns were add causing the code to malfunction. The code below is correct. My client for this week’s PowerShell class had a really interesting question. They needed to know where an account is being locked out at. OK, interesting. Apparently users hop around clients and forget to log off, leading to eventual lock out of their accounts. The accounts can be unlocked, but are then relocked after Active Directory replication. This problem is solved in two parts. The first one is to modify the event auditing on the network. The second part is resolved with PowerShell. The first part involves creating a group policy that will encompass your Domain Controllers. In this GPO, make these changes.
