Microsoft Patch KB3179575 causing authentication issues with Windows 2012 servers

Seems yet another Microsoft security patch is causing issues this month. KB3179575 which was in the August Patch Tuesday deployment is to fix issues with the Windows 2012 (not R2) operating system.

Oh No Not Again

Taken directly from the Microsoft site, this update includes quality improvements but no new operating system features are being introduced.

The key changes include:

  • Addressed issue that required users to wait up to 30 seconds after booting-up, before the device was available and ready for use.
  • Addressed issue that prevents the automatic deletion of old Dynamic Host Configuration Protocol (DHCP) backup files—Extensible Storage Engine (ESE) transaction logs.
  • Addressed issue that caused Cluster service on remaining nodes to stop unexpectedly when a failover cluster node experiences a power outage.
  • Addressed issue that causes a NFS service to stop responding on a two-node Windows cluster deployment, affecting clients to not be able reach an NFS share.
  • Addressed issue after installing KB3146706 that causes Office 2010 to stop responding when Enhanced Mitigation Experience Toolkit (EMET) is enabled.

At this stage it seems to be only affecting logons (authentication) to Windows 2012 Domain Controllers, again at this stage the only fix is to uninstall this update, or if you deployed this security update using Microsoft’s SCCM and SnaPatch, you can roll this update deployment back. There is no known fix at this stage.

You may also be interested in some other Microsoft patches KB3177725 & KB3176493 which are known to cause printing issues. These two security patches were also released this month as well as KB3176934 breaks Windows 10 Powershell.

How to Schedule a VMWare Snapshot.

Before I show you how to use SnapShot Master to create and schedule a VMWare Snapshot I will briefly describe what a snapshot is.

snapshot master

VMWare Snapshots are a crucial feature of the VMWare environment that allows you to roll back to a specific point in time in case of any issues. Snapshots can be created manually but, it is essential to have an automated process to make the process easier and more efficient. This is where SnapShot Master comes in.

What is a VMWare Snapshot?

VMWare Snapshots are a quick and easy way to provide a previous point in time in which you can revert your virtual machine to. Snapshots are a great feature to use prior to performing any risky upgrades, applying Windows updates or hardware reconfiguration as they give you the benefit of a fast roll back point should any issues occur.

When creating a VMWare Snapshot a differencing disk is created with *–delta.vmdk extension and an .vmsn file for configuration changes. the VMWare Snapshot preserves the state of the virtual machine at a specific point in time. (These new files leave the original VMDK files intact, hence allowing you to have a role back position.)

The more Snapshots you create, the more disk space you will utilise. It is also worth noting that the VM will also have its performance effected by each snapshot created.

VMWare Snapshot Tree

From within VMWare’s Vcentre, you can select the VM you want and view the VMWare Snapshot Tree. This shows each and every snapshot created for the virtual machine selected.

Each subsequent snapshot stems from the previous one with the delta changes stored on the snapshot’s disk which is the difference between the current state and the last snapshot created.

How to Schedule a Hyper-V Checkpoint.

Before I show you how to use SnapShot Master to create and schedule a Hyper-V checkpoint I will briefly describe what a checkpoint is.

HyperV checkpoint

What is a Hyper-V Checkpoint?

Hyper-V Checkpoints can be a lifesaver for IT administrators and developers alike. In this article, we’ll explore what a Hyper-V Checkpoint is and how to use it to roll back to a previous state in case of any issues.

Understanding Hyper-V Checkpoints

Hyper-V Checkpoints are essentially snapshots of a virtual machine that capture the VM’s state at a specific point in time. When you create a checkpoint, the virtual machine’s configuration and disk state are saved as differencing disks with .AVHD extension and an .XML file. If the VM was running during the checkpoint creation, additional files for the Virtual Machine Memory and Devices to be captured (.BIN and .VSV) may also be created.

Once a checkpoint has been created, any changes made to the virtual machine are saved to the differencing disk, leaving the original disk in a read-only state. This allows you to revert the virtual machine back to the checkpoint if any issues arise during upgrades, updates, or hardware reconfiguration.

Managing Hyper-V Checkpoints

SnapShot Master is a powerful software tool that can help IT administrators effectively manage their Hyper-V Checkpoints. With SnapShot Master, administrators can easily view all of their Hyper-V snapshots in one place, schedule the creation and deletion of snapshots on a schedule, and get detailed reporting on their Hyper-V snapshots.

By using SnapShot Master, administrators can avoid the hassle of manually managing their Hyper-V Checkpoints, which can be time-consuming and error-prone. Instead, they can rely on the software to handle the process automatically, ensuring that snapshots are created and deleted on a schedule that’s convenient for them.

SnapShot Master also provides detailed reporting on Hyper-V snapshots, giving administrators valuable insights into how their virtual machines are performing and helping them identify any issues that may need to be addressed. With this information, administrators can make informed decisions about how to optimize their virtual machines and ensure that they’re running at peak performance.

In summary, SnapShot Master is a must-have tool for any IT administrator who wants to effectively manage their Hyper-V Checkpoints. With its powerful features and intuitive interface, it makes it easy to schedule and manage snapshots, and provides valuable reporting that can help administrators optimize their virtual machines for maximum performance.

Why schedule your Hyper-V Checkpoints?

Hyper-V checkpoints allow administrators to capture the state of a virtual machine (VM) at a specific point in time. Scheduling Hyper-V checkpoints provides a number of benefits, including:

  1. Disaster Recovery: By regularly scheduling checkpoints, administrators can create a historical record of the state of a VM, which can be used for disaster recovery purposes. In the event of a failure or data loss, an earlier checkpoint can be used to restore the VM to a previous state.
  2. Testing and Development: Checkpoints can also be used to test changes to a virtual environment without affecting the production environment. Administrators can make changes to a checkpointed VM, test the changes, and revert to the checkpoint if the changes prove to be unsuccessful.
  3. Maintenance: Scheduling checkpoints can also simplify the process of performing maintenance on a virtual environment. By creating a checkpoint prior to performing maintenance, administrators can revert to the checkpoint if necessary, reducing the risk of downtime.
  4. Compliance: Regular checkpoint scheduling can also help organizations meet compliance requirements by providing a historical record of the state of virtual environments.

In summary, scheduling Hyper-V checkpoints provides a simple and effective way to ensure disaster recovery, simplify testing and development processes, minimize downtime during maintenance, and meet compliance requirements.

The benefits of scheduling Hyper-V checkpoints include:

  1. Data protection: Scheduling checkpoints provides a historical record of the state of a virtual machine (VM) at a specific point in time, which can be used for disaster recovery purposes. In the event of a failure or data loss, an earlier checkpoint can be used to restore the VM to a previous state.
  2. Testing and development: Checkpoints allow administrators to test changes to a virtual environment without affecting the production environment. This can be useful for software development, testing, and quality assurance processes.
  3. Maintenance: Scheduling checkpoints can simplify the process of performing maintenance on a virtual environment. By creating a checkpoint prior to performing maintenance, administrators can revert to the checkpoint if necessary, reducing the risk of downtime.
  4. Compliance: Regular checkpoint scheduling can also help organizations meet compliance requirements by providing a historical record of the state of virtual environments.
  5. Efficient use of resources: Checkpoints are stored as differencing virtual hard disks and do not consume a large amount of disk space. This allows administrators to create multiple checkpoints without consuming a significant amount of storage resources.

How to Create a Hyper-V Template for Deployment

How to Create a Hyper-V Template for Deployment

by | Jul 18, 2016 | Deployment, How To, Microsoft HyperV

Revolutionizing Document Archiving for SharePoint Online

How to Create a Hyper-V Template for Deployment

If you ever need to deploy Virtual Machines often a great time saving way is to create a VM Template for quick and easy deployment.

The main reason for creating a Hyper-V Template is to save time and effort when deploying Virtual Machines. By having a standardised and consistent configuration, deploying a new VM becomes a streamlined process that can be accomplished quickly and easily. This also reduces the chances of human error and helps ensure that all VMs deployed from the template have the same configuration, reducing the need for manual intervention and troubleshooting. Additionally, using a template helps enforce best practices and promotes standardisation across an organisation, improving the overall management and efficiency of the virtual infrastructure.

VM templates give you the advantage of a consistent configuration that is standardised format that is reusable.

To create a Hyper-V VM Template follow these steps;

What Are Hyper-V Templates?

A Hyper-V template is a pre-configured virtual machine (VM) that can be used to quickly create new VMs with identical configurations. Templates can include operating systems, applications, settings, and configurations. This means that you can deploy new VMs with just a few clicks, without having to manually install and configure each one.

Why Use Hyper-V Templates?

Using Hyper-V templates can save time and effort when deploying new VMs. Instead of creating each VM manually, you can simply select a pre-configured template that meets your needs. This can be especially useful for creating multiple VMs with identical configurations, such as in a test environment or for a specific application.

Templates also ensure consistency and standardization across your virtual infrastructure. By using the same template for each new VM, you can ensure that each VM has the same configuration and settings. This can make it easier to manage and troubleshoot your virtual infrastructure.

Hyper-V Template Benefits

There are several benefits to creating a Hyper-V template, including:

  1. Consistency and Standardization: By creating a Hyper-V template, administrators can ensure that all virtual machines (VMs) created from the template have a consistent configuration and operating system setup. This can help to reduce administrative overhead and minimize the risk of configuration errors.
  2. Faster Deployment: Creating a Hyper-V template allows administrators to deploy new VMs much faster compared to manually installing the operating system and configuring the necessary software on each individual VM.
  3. Reduced Storage Requirements: Hyper-V templates are stored as a single VHD (virtual hard disk) file, which can be much more efficient in terms of storage compared to storing multiple VMs each with their own VHD file.
  4. Increased Scalability: By using a Hyper-V template, administrators can quickly and easily create new VMs as needed to support business growth and changing requirements.
  5. Improved Disaster Recovery: With a Hyper-V template in place, administrators can quickly recreate VMs in the event of a disaster, reducing downtime and minimizing the impact on the business.
  6. Enhanced Security: By using a Hyper-V template, administrators can enforce security policies and configuration standards for all VMs created from the template, helping to maintain a secure computing environment.
  7. Improved Compliance: For organizations that must comply with industry or regulatory standards, using a Hyper-V template can help ensure that all VMs meet the necessary requirements.

Now once you have installed the Windows Operating System, do not join the domain. Log on to the VM, open a command prompt and go to the Windows, System32, Sysprep folders then run sysprep.exe

Sysprep (System Preparation) is a Microsoft utility tool designed for system administrators to automate the deployment of Windows operating systems. It is used to prepare an operating system for disk cloning or for delivery to end-users.

Sysprep performs several key tasks, including:

  1. Generalizing the system: Sysprep removes specific information from the Windows installation that is unique to the system, such as the security identifier (SID), computer name, and drivers.
  2. Configuring the Windows Security settings: Sysprep can reset security settings to default settings, ensuring that all new installations of the operating system will have the same security settings.
  3. Removing the activation files: Sysprep can remove activation files, allowing the cloned operating system to be activated on a new computer.
  4. Shutting down the system: After preparing the operating system, Sysprep shuts down the computer, making it ready for disk imaging or delivery to an end-user.

Sysprep is a critical component in the deployment of Windows operating systems and is an essential tool for system administrators. It enables them to efficiently and easily deploy operating systems to multiple computers, ensuring that each installation is fully configured and ready to use.

Hyper-V Template Creation Warning

Next a warning is shown that you are about to convert this VM to a template. “Creating a template will destroy the source virtual machine “vm name”. The virtual hard disk of the virtual machine will be generalized to create the new template and any user data of the virtual machine may be lost. To prevent this, you can create a clone of “vm name”  before using it to create a template. 

Make sure you understand what you are committing this VM to and click Yes to continue.
