The details of the event scenario and the design points for Beginner Event #2 of the 2012 PowerShell Scripting Games can be found on the “Hey, Scripting Guys! Blog”.

Use the simplest command that will work. You do not need to write a script. Return the results to the screen, not to a file. You may use aliases. I started Read more [...]

Importing PowerShell Modules and Locating Added Cmdlets

Want to add a feature to a Windows Server 2008 R2 machine using PowerShell? That functionality is part of the ServerManager PowerShell Module that's install by default on 2008 R2.

Game On! The 2012 PowerShell Scripting Games

Since this is my first year entering the PowerShell Scripting Games, I’m only submitting scripts for the beginner events but I’m also taking a look at the advanced ones to get an idea of what kind of knowledge is needed for them. It’s not too late to join in on the fun. Make sure you read the requirements of each event carefully, create your script, test it, and think about it for a while before submitting it. I had four stars on the first Beginner Event: Another judge must have given me Read more [...]

How Do I Get-Started With PowerShell?

Commands in PowerShell are called cmdlets (pronounced "command lets") and they are in the form of singular verb-noun commands like Get-Alias (not Get-Aliases). In my opinion, there are three cmdlets that are the key to figuring out how to use PowerShell and finding help when you need it. These cmdlets are: Get-Help (help) Get-Command (gcm) Get-Member (gm) Get-Help or Help for short. Help isn't actually an alias, but it works exactly the same way if your using the PowerShell ISE. I've Read more [...]

Using PowerShell to Ace the Scripting & Regular Expression Interview Question

Last week I saw a tweet that referenced a couple of interesting articles on interview questions for programmers. I'm no programmer, but one of them (Steve Yegge's The Five Essential Phone-Screen Questions) had an interesting question about identifying which of 50,000 web pages had phone numbers in them. You have to identify all of the web pages with phone numbers hard coded in them. All of the web pages are HTML files in a directory tree under a folder named website. The phone numbers are in the Read more [...]

Confusion on PowerShell Parameterized Functions

I've run into an issue with PowerShell functions that I don't understand. I guess my confusion is most of the examples I've found online and in books don't work the way the authors explained (at least not for me). The problem is when I define a parameter inside a function, that parameter is not accessible when running the script. When I move the parameter outside of the function, it's accessible and it works without issue. I'm guessing this is because of Read more [...]

Where Do I Find This Thing Called PowerShell?

If you’re running Windows 7, you already have PowerShell 2.0 installed. It’s located under “All Programs > Accessories > Windows PowerShell”. I’m running a 64bit version of Windows 7 so I have both 64bit and 32bit (x86) links in my start menu. I prefer the PowerShell ISE (Integrated Scripting Environment) as apposed to the PowerShell Console. I use the 64bit version and have never run into an issue where I needed to use the 32bit (x86) versions. According to the Microsoft Support Read more [...]

Get-WmiObject : The RPC Server is Unavailable. (Exception from HRESULT: 0x800706BA)

This week while working with some PowerShell scripts that retrieve WMI information from remote servers, I ran into an issue where I was able to return results from Windows 2008 R2 servers without issue but was unable to return results from Windows 2008 (non-R2) servers even though they had PowerShell 2.0 installed and as far as I could tell they were configured exactly the same as the Windows 2008 R2 servers. Here's the error I received: Get-WmiObject : The RPC server is unavailable. (Exception Read more [...]

Your Search Cannot Be Completed Because This Site Is Not Assigned To An Indexer.

Your attempting to search a SharePoint 2010 Site (Foundation Edition) and you receive the following error message "Your search cannot be completed because this site is not assigned to an indexer." Search has never been configured for this SharePoint farm so we'll be configuring it from the ground up. First you'll need two service accounts, one for the search service to run as and one for the actual crawling. Todd Klindt has a great blog on service accounts that I use for reference. I used the Read more [...]

Add an Additional Web Front-end Server to an Existing SharePoint 2010 Farm using PowerShell

You've followed the instructions in my other three blogs and built a SharePoint 2010 farm (not a stand-alone installation) with one or more web front-end servers. Per one of the notes in a TechNet article I found:  “As a best practice, we recommend the operating system on the new server should be at the same service pack level and have the same security updates and other hotfixes as the existing farm servers.”  This article also shows the steps that I’ll be demonstrating in this blog. All Read more [...]
