You need to have an Active Directory domain in place. I'm picking up where I left off in my previous blog article "Use PowerShell to Create a New Active Directory Forest on Windows 2019 Server Core Installation (no-GUI)".
The procedure shown in this blog article is for demonstration purposes only.
Install the DHCP server feature.
Install-WindowsFeature -Name DHCP
Add the DHCP scope to the server.
Add-DhcpServerv4Scope -Name '192.168.129.x' -StartRange 192.168.129.101 -EndRange 192.168.129.199 -SubnetMask 255.255.255.0
Options can either be set at the scope level.
Set-DhcpServerv4OptionValue -ScopeID '192.168.129.0' -DNSServer 192.168.129.100 -DNSDomain mikefrobbins.com -Router 192.168.129.1
You have a fresh installation of Windows Server 2019 that was installed using the default installation type of server core installation (no-GUI). This server will be the first domain controller in a brand new Active Directory forest. You've completed the following configuration prior to attempting to turn this server into a domain controller:
Install all the available Windows Updates
Set the time zone
Set the computer name
Set a static IP address
Log into the server and launch PowerShell Read more [...]
You've probably heard, as I have, that Visual Studio Code (VSCode) is the latest whiz-bang editor that you should be using for PowerShell (and I am for development of PowerShell code on my primary workstation). One word of caution though is to make sure to put things into perspective and not be so quick to shun people away from using the PowerShell Integrated Scripting Environment (ISE), depending on how they're using it.
I recently received a comment about my choice of editors for a particular Read more [...]
Windows 10 version 1709 introduced a default Hyper-V virtual switch which is installed when the Hyper-V role is added. As you can see in the following example, by default on Windows 10, the default virtual switch does not exist because the Hyper-V role hasn't been added.
Now that the Hyper-V role has been added, you can see that a new network adapter named "vEthernet (Default Switch)" exists.

While you wouldn't think this Read more [...]
As I previously mentioned a little over a month ago in my blog article "PowerShell Script Module Design Philosophy", I'm transitioning my module build process to a non-monolithic design in development and a monolithic design for production to take advantage of the best of both worlds. Be sure to read the previously referenced blog article for more details on the subject.
My goal is to write a reusable tool to retrieve the necessary information from a non-monolithic script module that's necessary Read more [...]
This blog article is the third in a series of learning about the PowerShell Abstract Syntax Tree (AST). Be sure to read the other two if you haven't already.
Learning about the PowerShell Abstract Syntax Tree (AST)
Learn about the PowerShell Abstract Syntax Tree (AST) – Part 2
Learn about the PowerShell Abstract Syntax Tree (AST) – Part 3
In this blog article, I'll be specifically focusing on finding the AST recursively.
I'll start off by storing the path to one of my functions Read more [...]
In my previous blog article a few weeks ago on "Learning about the PowerShell Abstract Syntax Tree (AST)", I mentioned there was an easier way to retrieve the AST so that you didn't have to cast everything to a script block. There are two .NET static methods, ParseFile and ParseInput, that are part of the Parser class in the System.Management.Automation.Language namespace which can be used to retrieve the AST.
First, I’ll store the content of one of my functions in a variable.
$Code = Get-Content -Path U:\GitHub\Hyper-V\MrHyperV\public\Get-MrVmHost.ps1 -Raw

I recently received a request to write a script for monitoring IIS websites and their application pools on a specific Windows 2012 R2 server and start them if they were stopped. This is something I created fairly quickly and thought I would share.
I always try to centralize any scripts I write and have them run on a job server instead of the actual server they're querying. That way I don't have multiple versions of the same script floating around on different servers. I can easily use this same Read more [...]
