Getting User Accounts with identical GivenName and SurName

I am taking a break from writing some custom formatting files to take a look at what is happening on PowerShell.com. One IT Pro is trying to look for all user accounts with the same GivenName and SurName property values. He discovered that this will not work.

Get-ADUser -Filter 'GivenName -eq SurName'

Here is the error message

Get-ADUser : Error parsing query: 'GivenName -eq SurName' Error Message: 'syntax error' at

position: '15'.

At line:1 char:1

+ Get-ADUser -Filter 'GivenName -eq SurName'

+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

+ CategoryInfo : ParserError: (:) [Get-ADUser], ADFilterParsingException

+ FullyQualifiedErrorId : ActiveDirectoryCmdlet:Microsoft.ActiveDirectory.Management.ADF

ilterParsingException,Microsoft.ActiveDirectory.Management.Commands.GetADUser

The problem is that the Get-ADUser cmdlet is looking for a property on the left and a value to match it to on the right. It is not looking to match the values of two properties. At least not in this format. Here is what I came up with.

Get-ADUser -filter * |

Where-Object -FilterScript {$_.GivenName -eq $_.SurName}

We are breaking the “Filter to the left” rule because we simply cannot filter the values of to object properties with the Get-ADUser cmdlet. This is where we can use plan B, Where-Object. Where-Object is there is the previous cmdlet cannot filter the way you want it to.

Well, back to my coding. Thank you for the break.

Sticky Key problem between Windows Server 2012 and LogMeIn

This week I instructed my first class using Windows Server 2012 accessed via LogMeIn and discovered a Sticky Key problem every time you press the Shift key. Here is my solution to resolve this. First off, in the Preferences of LogMeIn for the connection to the Windows Server, click General . Change the Keyboard and mouse priority to Host side user and click Apply at the bottom. On the Windows 2012 server, open the Control Panel – Ease of Access – Change how your keyboard works . Uncheck Turn on Sticky Keys . Click Set up Sticky Keys . Uncheck Turn on Sticky Keys when SHIFT is pressed five times . Click OK twice. If you are using Windows Server 2012 as a Hyper-V host, you will need to redo the Easy of Use settings on each guest operating system in order to avoid the Sticky Key Problem. Updated Information: March 20, 2013 If you continue to have problems, Uncheck Turn on Filter Keys .

How to run GPResult on a remote client with PowerShell

In the past, to run the GPResult command, you would need to either physically visit this client, have the user do it, or use and RDP connection. In all cases, this will disrupt the user. First, you need PowerShell remoting enabled on the target machine. You can do this via Group Policy . Open PowerShell and type this command. Invoke-Command –ScriptBlock {GPResult /r} –ComputerName <ComputerName> Replace <ComputerName> with the name of the target. Remember, the target needs to be online and accessible to you.
