VMware ESXi has an option which allows us to revert back to previous version after upgrade. You might need it in case you don’t see your network card (driver not on the ISO) or you see the NIC perfectly, but network isn’t stable after your upgrade.

Fairly often, unexperienced end users get caught on some website which uses malware or newly some crypto miners which uses up to 70% of your PCs power to mine a cryptocurrency for some hackers. So how to protect at best those end users? One of the new ways is to use Microsoft’s built-in utility called Windows Defender Application Guard (WDAG).The tool is designed for W10 Enterprise version only and the system has to support to run Hyper-V role. Microsoft introduced a new layer of defense-in-depth protection which uses Hyper-V for isolation purposes.

Before we dive into how to enable Active Directory Recycle Bin in Windows Server 2016, we will first explain what it is and when Microsoft introduced this feature. Active Directory Recycle Bin simply allows you to restore deleted objects from Active Directory. It can be a user account, computer account or a whole Organizational Unit (OU). Who did not accidentally delete an AD object in his career? Without this feature enabled, you had only a few choices. Either you could restore if you used a backup solution allowing you to restore individual AD objects (many virtualization backup vendors do that nowadays). Or you have had less chance and your AD server wasn’t configured to be backed up and you have to recreate the user and reinstall his profile on his computer.  

VMware vCenter server appliance is evolving with every major release of VMware vSphere Suite. The product, which manages the whole vSphere infrastructure, can be either installed on a Windows server or deployed as pre-configured virtual appliance called vCenter Server Appliance (VCSA). Over several VCSA releases, VMware managed to make this product equal to the Windows-based one, and it pushes the development even further so now the Linux based product has more features than the vCenter server installed on Windows. However, many VMware admins are also Microsoft guys and like the graphical user interface to work with. That’s why today we’ll have a look at 5 Tips to manage this appliance. We won’t go into the configuration steps within this post as this has been documented many times.

One of the best freeware applications which gather a lot of information about VMware vSphere id definitely RVTools utility. Today we’ll have a look at some features which are the most useful ones for IT admins. RVTools is a Windows .NET 4.0 application which uses the VI SDK to display information about your virtual environments. So, before you download and install the tool, you’ll need to check if your Windows system has at least .NET 4.0 installed.

VMware Photon OS has been the latest OS used for vCenter Server Appliance 6.5. This is the latest move from SUSE Linux Enterprise Server (SLES) as VMware wants to own the Operating system (OS) and manage its development cycles and patches releases. Things that aren’t possible on Windows OS or SLES. That’s why VMware used Photon Linux and continues to develop Photon OS which is optimized for VMware platforms.

Many IT administrators or virtualization guys run their homelabs at home. It is a good way to learn new technologies, be able to break things in a lab to get stronger skills. It is sometimes a challenge, to squeeze as much RAM as possible from it. The main challenge is always a memory utilization. VMware VMs are getting memory hungry all the time and they are not “optimized” for Homelab use, but rather for production environments. Yes, it is the main purpose of those VMs after all.

I did previously setup during a few occasions, VPN access on Windows Server 2012 R2, but haven’t tested that on the newly released Windows Server 2016. Remote access role is a VPN which protects the network connection or your remote connection from one side to another and protecting both sides from attacks or data sniffing as VPN protocol uses a tunnel inside of a standard data connection.

It is not new that VMware vCenter Server Appliance (VCSA) is a very popular option, especially for small businesses which can save money on an additional Windows Server license. It is a prepackaged and preconfigured virtual appliance with PostgreSQL database, vCenter server 6.5 components and also (in case you deploy “all-in-one” VM) Platform services Controller that contain all of the necessary services for running vCenter Server such as vCenter Single Sign-On, License service, and VMware Certificate Authority.
