Welcome to PowerShell Hell

I finally figured out why the error messages in PowerShell are in bright red. It's because it's the color of flames and/or red hot coals and it means you may be in PowerShell Hell. That's what recently happened when I updated the Antivirus on my PC from Eset NOD32 version 4 to version 5. A few days after updating, I was in PowerShell Hell as shown below: When trying to run Get-ChildItem against WSMan:localhost, I received the following: Get-ChildItem : WS-Management cannot process the request.

Using PowerShell to Find Expiring SSL Certificates & the Websites they’re Associated with

Have you recently received a notification about an expiring SSL certificate and don't remember where all it's used at?

Symantec Backup Exec 2012 Adds PowerShell Support!

The latest version of Backup Exec, version 2012 adds support for PowerShell.

You'll have to import the server manager module (Import-Module Read more [...]
