How to See a Cmdlet’s Code

This last week I had the privilege of speaking at the PowerShell Summit Asia in Singapore. After an 11 hour day of speaking, you better believe that I had a lot of attendees asking me questions over the following 2 days. A really good one that stuck in my head involves how to see the code that was used to write a cmdlet. Hey, I teach PowerShell so this is a good one.

PowerShell cmdlets are actually either a “cmdlet” or a “function”.

PS C:\> Get-Command -Name Get-Process, Get-SMBShare

CommandType Name Version Source

----------- ---- ------- ------

Cmdlet Get-Process 3.1.0.0 Microsoft.PowerShell.Management

Function Get-SmbShare 2.0.0.0 smbshare

Cmdlets are actually created from C# while functions are created with PowerShell. Since C# is compiled we cannot crack them open to see what makes them tick without some extra software. However, you can very easily see the code from a function

PS C:\> Get-Command -Name Get-SMBShare | Select-Object -ExpandProperty ScriptBlock | Out-File -FilePath ##Someplace to put it "

Set the –FilePath to a txt or PS1 file so you can look at the code.

It is no secret that I advocate to practice of “never reinvent the wheel”. In other words if you need to know how a function did something, just look at the code.

Personally, I have never tried it. Go ahead and let us know how it goes.

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 .

With the AD Recycle Bin Turned on, What Happens when you Create a User Account with a Password that does not meet the Password Policy?

This was an interesting observation from one of my Windows Server 2012 classes. While working with the AD Recycle bin in a lab, one of my students discovered some interesting accounts that were created. When he created user accounts that did not meet password complexity requirements, an account is temporarily made and then deleted. When a new password is provided that meets the password requirements, then a new account is made. We discovered this in two places. First off in the Active Directory Administrative Center. This is what caused the initial confusion. Take a look. This is in the Deleted Objects OU. You can see multiple deleted accounts for Test2 and one for Test3. Test3 is a valid, functioning user account. Using the PowerShell command Get-ADObject –IncludeDeletedObjects –Filter * –Properties ObjectSID we can see that indeed, two accounts were created, with one of them deleted. Notice the RID portion of the SID is different. ...

Where did a User’s Account Get Locked Out?

Updated: May 15, 2015 When this article was originally published, two extra carriage returns were add causing the code to malfunction. The code below is correct. My client for this week’s PowerShell class had a really interesting question. They needed to know where an account is being locked out at. OK, interesting. Apparently users hop around clients and forget to log off, leading to eventual lock out of their accounts. The accounts can be unlocked, but are then relocked after Active Directory replication. This problem is solved in two parts. The first one is to modify the event auditing on the network. The second part is resolved with PowerShell. The first part involves creating a group policy that will encompass your Domain Controllers. In this GPO, make these changes. Expand Computer Configuration \ Policies \ Windows Settings \ Security Settings \ Advanced Audit Policy Configuration \ Audit Policies \ Account Management Double click User Account Management C...
