Windows 11 version 25H2 introduces a new Group Policy setting, Configure maintenance windows for automatic updates, that lets you define precise time windows for downloading, installing, and restarting after updates. The policy ships with version 3.0 of the ADMX administrative templates and is currently available only in Windows 11 Insider Preview builds. It takes priority over several existing update-related policies, but the interaction rules are only partially documented.
After installing the most recent Updates on their Domain Controllers, some readers have reported in the comments that they experienced that the Local Security Authority Subsystem Service (LSASS) process on their Domain Controllers continually increases memory usage making their Domain Controllers become unresponsive and even automatically restart…
Greetings again AskDS!
Ryan Ries here. Got something exciting to talk about.
You might be familiar with the original Lingering Object Liquidator tool that was released a few years ago.
Today, we’re proud to announce version 2 of Lingering Object Liquidator!

Let’s say that you have a GPO that is scoped to a specific security group. If you add a computer to this security group, you would normally need to restart in order for the computer to see that it is now a member of this group. To bypass this, you can delete the system’s Kerberos ticket and run GPUpdate. The computer will magically see its new group membership without a restart.

So as many of you may know, yesterday Microsoft released a security hotfix that changed the behavior of Group Policy. Put simply if you have a security group filtered User Group Policy Object and you also removed the “Authenticated Users” group from the policy it will no longer apply after you install MS16-072.

Hello, Ryan Ries here again with some juicy new Active Directory hotness. Windows Server 2016 is right around the corner, and it’s bringing a ton of new features and improvements with it. Today we’re going to talk about one of the new things you’ll be seeing in Active Directory, which you might see referred to as “expiring links,” or what I like to call “temporary group memberships.”
One of the challenges that every security-conscious Active Directory administrator has faced is how to deal with contractors, vendors, temporary employees and anyone else who needs temporary access to resources within your Active Directory environment. Let’s pretend that your Information Security team wants to perform an automated vulnerability scan of all the devices on your network, and to do this, they will need a service account with Domain Administrator privileges for 5 business days. Because you are a wise AD administrator, you don’t like the idea of this service account that will be authenticating against every device on the network having Domain Administrator privileges, but the CTO of the company says that you have to give the InfoSec team what they want.
(Trust me, this stuff really happens.)

The proper way to remove a DC server in an Active Directory infrastructure is to run DCPROMO and remove it. The following video provides an example of these steps...

In the last post of this series, I described how to prepare your VirtualBox environment. In today’s post, I’ll show you how to install the Ubuntu server with the help of the netboot.xyz iPXE .iso.

If you want to run a domain controller on your network but don’t have access to a Windows Server license, you can use SAMBA, the free open-source software, and VirtualBox, the free virtualization software. We’ll describe the procedure for setting up a virtual server using VirtualBox and netboot.xyz iPXE and move on to setting up your domain controller with SAMBA.

The name of the free tool Bulk Password Control is perhaps a bit misleading because the free tool enables you to automate all kinds of bulk modifications on Active Directory user objects with a fast to use GUI.
You know this popular picture of the GUI admin who clicks all day to reset user passwords after a security breach. Bulk Password Control is a nice example that proves that such tasks can be quickly done with a GUI tool without much click-click.

So, let me kick off this series in which I’ll be sharing what it feels like to virtualize and clone Active Directory Domain Controllers safely on both platforms, with a blogpost on finding out whether your virtual Domain Controllers may benefit from the VM-GenerationID on the VMware-based hypervisors and, thus, may be safely virtualized and cloned.
It is a great pleasure to be able let you know that v1 of the Active Directory Authentication Library (ADAL) for .NET has reached General Availability! You can add the library to your projects directly from Visual Studio (search for ADAL) or you can download the NuGet package directly from here

This breakdown of Kerberos settings and how they correspond to AD provides much-needed clarity
This ongoing need to clarify how Kerberos works and how it fails is a result of the fact that—although Kerberos remains the same—the services that use it and the ways they use it are often unique. The aspects that remain the same in each scenario, however, are what the settings in Active Directory (AD) are intended to address, and the difficult-to-interpret messages you’ll see when things fail.

there are serious integration problems between Apple Mac OS X 10.7 Lion and Active Directory Domain Services (AD DS). Specifically, we are seeing (a) sluggish binding between the Macs and AD; (b) super-slow domain logons; and (c) completely blocked domain logons.
