How to Exceed the Maximum Number of Allowed Objects from Get-ADGroupMember, Get-ADPrincipalGroupMembership, and Get-ADAccountAuthorizationGroup cmdlets

One of the reason why the cmdlets in the ActiveDirectory module limit the properties from objects or the number of objects returned is because you may accidentaly ask for 2 billion objects if you are not careful. A recent question from one of my posts asked about how to exceed the threshold for Get-ADGroupMember.
The error that the user received was:
Get-ADGroupMember : The size limit for this request was exceeded
The default limit is 5000 objects. This is a limitation imposed by the Active Directory Web Service. ADWS is a requirement for utilizing the ActiveDirectoy module for PowerShell. If you have multiple instances on ADWS on multiple Domain Controllers, you will need to perform this procedure on each one. Since you do not know for sure which DC your client will bind to, changing this setting on all of the ADWS services will prevent random issues from happening in the future.
On the file c:\Windows\ADWS\Microsoft.ActiveDirectory.WebServices.exe.config
After the <appSettings> tag, place this entry:
<add key=”MaxGroupOrMemberEntries” value=”10000”/>
This assumes that you need to return up to 10000 objects from these cmdlets. Also take note that you will still have a 5 minute timeout imposed on all your requests. If you cannot recover the information in 5 minutes, the request will fail. Filter your request to contain only the information that you need to work with.
Your next steep is to stop and then restart the ADWS service on the Domain Controller.

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 .

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.
