Q: How do I delete an OU in Server 2008 that was created with deletion protection?

In Server 2008, when you create a new OU, by default the Protect container from accidental deletion checkbox if checked. This helps to prevent you, or someone else, from deleting something they should not. The problem comes from what to do if you really do need to delete it.

• Enable Advanced Features in Active Directory Users and computers.
• Open the OU’s properties
• Click the Security tab.

• Click the entry that starts as Deny Everyone.
• Click Edit.
• In the Deny column, remove the checks for Delete and Delete Subtree.
• Click OK 3 times.
You can now delete the OU.

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.

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 .

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.
