How to add a PowerShell Snapin

Powershell is integrated into almost off of Microsoft's latest software. This is one of the reasons why PowerShell is expandable. One way that Powershell is expanded is through the use of Snapins. When you install software, say Exchange 2007, you also install the Exchange PowerShell Snapins for that product. For this demonstration, we will be using Exchange 2007 as our example software.

Before we install the Snapins, lets to a little test. Execute the following commands.

$a = Get-Command

$a.Count

This will list the number of cmdlets currently on your computer. On my test computer, I have 180 cmdlets.

If you have not installed Exchange yet (or what ever Microsoft product you want to install), do so now. If this is a workstation, you may only need to installed the support tools for the product. Read the product documentation to determine what you need to do.

Get-PSSnapin

This commmand should list the currently installed snapins on your computer.

Get-PSSnappi -registered

This will list the snapins that have registered with PowerShell, but have not yet installed. Below is what I received.

Name: Microsoft.Exchange.Mamangement.PowerShell.Admin

PSVersion: 1.0

Description: Admin Tasks for the Exchange Server

Name: Microsoft.Exchange.Management.PowerShell.Supprt

PSVersion: 1.0

Description: Support Tasks for the Exchange Server

At this point, we need to add the snapings to PowerShell with the following commands:

Add-PSSanpin Microsoft.Exchange.Management.PowerShell.admin

Add-PSSanpin Microsoft.Exchange.Management.PowerShell.Support

Now to continue on with our little experiment type this:

$b = Get-Command

$b.count

This will list the number of new cmdlets added to PowerShell. My number came out to be 525. By adding the Exchange 2007 PowerShell Snapins, we extended PowerShell's capabilties by 345 cmdlets. Go ahead and type Get-Command to see them all.

How can one get PSVersion 2.0 beside that? Even with the SP2 version of Exchange 2007 which says it has Powershell 2.0 support, I still see 1.0 and not 2.0.

I am trying to run a ASP.NET 2.0 app that requires Exchange Management Admin 2.0 and not 1.0

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. ...

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 .

Backup and Restore AD LDS with DSDBUTIL.exe

Active Directory Lightweight Directory Services allow you to create a directory service that allows applications to have access to user accounts, groups, and authentication similar to Active Directory Domain Services. The big advantage here is that the schema of the directory service will not be bound by the rules of an Active Directory database. Exchange 2007/2010, for example, use an instance of AD LDS on the Edge Transport Server to provide for user authentication from the internet. Because your Active Directory database is not exposed to the internet, this is more secure. Applications will handle most of the dirty work should they require AD LDS. You may want to make sure the database is being backed up and also have a restore plan in place. Should the database become corrupt, the application that uses that database will fail. This document will walk you through backing up and restoring an instance of AD LDS using the dsdbutil.exe command. Fi...
