Updated ouut-of-band (OOB) updates are released for March 2024 for Windows Server Domain Controllers

Microsoft has identified an issue that affects Windows Server domain controllers (DCs), and has expedited a resolution that can be applied to affected devices. Out-of-band (OOB) updates have been released for some versions of Windows today, March 22, 2024, to addresses this issue related to a memory leak in the Local Security Authority Subsystem Service (LSASS). This occurs when on-premises and cloud-based Active Directory domain controllers service Kerberos authentication requests.

This issue is not expected to impact Home users, as it is only observed in some versions of Windows Server. Domain controllers are not commonly used in personal and home devices.

Updates are available on the Microsoft Update Catalog only. These are cumulative updates, so you do not need to apply any previous update before installing them, and they supersede all previous updates for affected versions. If your organization uses the affected server platforms as DCs and you haven’t deployed the March 2024 security updated yet, we recommend you apply this OOB update instead. For more information and instructions on how to install this update on your device, consult the below resources for your version of Windows:

  • Windows Server 2022KB5037422
  • Windows Server 2019: Available soon
  • Windows Server 2016KB5037423
  • Windows Server 2012 R2KB5037426

Note: The OOB release for Windows Server 2019 will be released in near term.

Windows Server 2025 “Preview” deployment with Packer

As Windows Server 2025 Preview is officially released, I wanted to test a  automated build of the Windows Server 2025 Preview release. So that I can deploy this in my home lab and going to test the new features if I can find the time….

About Hashicorp Packer

Hashicorp Packer is a self-contained executable producing quick and easy operating system builds across multiple platforms. Using Packer and a couple of HCL2 files, you can quickly create fully automated template(s) with latest Windows Updates en VMware Tools. When you schedule a fresh builds after patch Tuesday  you have always an up-to-date and fully secured template.

When using VMware customization tools. You can spin up vm’s in minutes.

Automated Windows Server 2025 “Preview” Build

Files you need?
The files and versions I am using at the time of this writing are as follows:

Outside of downloading both Packer and Windows Server 2022 Preview build, you will need the following files:

  • windowsserver2025.auto.pkrvars.hcl – houses the variable values you want to define.
  • windows2025.json.pkr.hcl – the Packer build file
  • Answer file – Generated with Windows System Image Manager (SIM) you can download the file below
  • Custom script file(s) – optional

Other considerations and tasks you will need to complete:

  • Copy the Windows Server 2025 ISO file to a vSphere datastore

Windows Server 2025 unattend Answer file for the automated Packer Build

Like other automated approaches to installing Windows Server, the automated Windows Server 2025 Packer build requires an answer file to provide answers to the GUI automatically and other installation prompts that you normally see in a manual installation of Windows Server.

You will find the scripts here: https://github.com/WardVissers/Packer-Win2025

The only problem that I had was: Switching from Nic from Public to Private

# Set network connections profile to Private mode.

Write-Output ‘Setting the network connection profiles to Private…’

do {

    $connectionProfile = Get-NetConnectionProfile

    Start-Sleep -Seconds 10

} while ($connectionProfile.Name -eq ‘Identifying…’)

Set-NetConnectionProfile -Name $connectionProfile.Name -NetworkCategory Private

Windows Server 2025 Preview (Build: Canary 26052)

I had some time to check out the new version of Server 2025.

For the full upcomming features check: https://ignite.microsoft.com/en-US/sessions/f3901190-1154-45e3-9726-d2498c26c2c9?source=sessions

Download Server 2025 Preview: https://www.microsoft.com/en-us/software-download/windowsinsiderpreviewserver

Deploy Windows Core Server 2022 with Server Core App Compatibility Feature on Demand with Packer

I while ago I started with parker to create simple templates for use in my homelab.

It take some time to find the rights scripts and learning en understanding the HCL2 coding

But in related to Security reasons I want to use a Windows Core Server the smaller footprint.

What is Server Core App Compatibility Feature on Demand: https://learn.microsoft.com/en-us/windows-server/get-started/server-core-app-compatibility-feature-on-demand

Installing Features on Demand through Powerschell contains a bug. You may see “failure to download files”, “cannot download”, or errors like “0x800F0954” or file not found.

To Solve that I created I powerschell script to run the install twice: featuresondemand.ps1

You can find al the needed files on my Public Github Packer repository: https://github.com/WardVissers/Packer-Public

When running is showing like this:

VMware Seciroty Violation message

In VM vmware.log, there is ‘Image DENIED’ info like the below:
2023-02-15T05:34:31.379Z In(05) vcpu-0 – SECUREBOOT: Signature: 0 in db, 0 in dbx, 1 unrecognized, 0 unsupported alg.
2023-02-15T05:34:31.379Z In(05) vcpu-0 – Hash: 0 in db, 0 in dbx.
2023-02-15T05:34:31.379Z In(05) vcpu-0 – SECUREBOOT: Image DENIED.

To identify the location of vmware.log files:

  1. Establish an SSH session to your host. For ESXi hosts
  2. Log in to the ESXi Host CLI using root account.
  3. To list the locations of the configuration files for the virtual machines registered on the host, run the below command:

#vim-cmd vmsvc/getallvms | grep -i “VM_Name

  1. The vmware.log file is located in virtual machine folder along with the vmx file.
  2. Record the location of the .vmx configuration file for the virtual machine you are troubleshooting. For example:



This issue is resolved in VMware ESXi 7.0 U3k, released on February 21st 2023. Build 21313628

  • Virtual machines running on any version of vSphere ESXi 8.0.x are not impacted by this issue
  • vSphere ESXi 6.7 is End of general Support. For more information, see The End of General Support for vSphere 6.5 and vSphere 6.7 is October 15, 2022.
  • If you already face the issue, after patching the host to ESXi 7.0 Update 3k, just power on the affected Windows Server 2022 VMs. After you patch a host to ESXi 7.0 Update 3k, you can migrate a running Windows Server 2022 VM from a host of version earlier than ESXi 7.0 Update 3k, install KB5022842, and the VM boots properly without any additional steps required.

2684681          Iscsicpl.exe process stops responding when you try to reconnect a storage device to a computer that is running Windows Vista, Windows Server 2008, Windows 7, or Windows Server 2008 R2


2670567 “0x000000027” Stop error when you copy a file from a redirected folder in Windows 7 or in Windows Server 2008 R2

CPU usage is high when you use RPC over HTTP protocol in Windows 8.1 or Windows Server 2012 R2

Consider the following scenario that takes Microsoft Exchange Server 2013 as an example:

  • The Mailbox server role is enabled in Exchange Server 2013.
  • Exchange mailboxes use extended MAPI to communicate with the Exchange Server.
  • The extended MAPI uses Microsoft RPC over HTTP (remote procedure call over HTTP) protocol.
  • Many clients (such as mobile devices) are dropping connections to the Exchange Server.

In this scenario, the CPU usage on the Exchange server may reach 100 percent.\
