Want VM Reliability and Uptime? Hyper-V on Server Core

While at TechEd last month I heard two things that I've been preaching for a while. Server Core installation (no-GUI) is the recommended installation type beginning with Windows Server 2012. I've been saying this for a while when it comes to Windows Server 2008 R2. Server Core: Reliability and Uptime In each of three datacenters that I support there are multiple Hyper-V servers that run Windows Server 2008 R2 w/SP1 with the Core Installation (Server Core).

Use PowerShell to Determine What Roles are Added When Turning a Windows 2012 Server into a Domain Controller

Goal: Determine what roles are installed when turning a Windows Server 2012 machine into a domain controller.

The following one liner would be used in PowerShell version 2 to accomplish this task and the syntax is compatible with version 3: PowerShell version 3 has simplified syntax when using the Where-Object cmdlet Read more [...]

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.

Use PowerShell to Audit Logon Authentication Type

Want to know what type of authentication mechanism is being used when users log onto your servers? This script pulls the information from the event logs to determine how users are being authenticated. It uses Get-Winevent with the -FilterXPath parameter. That parameter and what the logon type numeric codes translate to are a couple of things that I haven't seen much documentation on.
