How to clone and Sysprep a Windows Server running on VMware Workstation

Clone-SysPrep

Cloning a server takes an exact copy of an existing machine. A cloned server is, for most purposes, an exact copy of the source. When a server is cloned, the SID is retained. Server cloning is a useful tool, if your need is to setup up a server similar to what you already have, and wish to skip the hassle of configuring a new server from scratch. Cloning requires that your server is shut down.

Part B – Sysprep: After cloning a virtual machine in VMware/Proxmox/Hyper-V/VirtualBox, you may need to run the system prepare tool also referred to as Sysprep.exe in windows. In a domain-joined environment, Sysprep will strip off the unique security identifier (SID) and prevent two devices from having the same IP or name.

Sysprep prepares a Windows installation (Windows client and Windows Server) for imaging, allowing you to capture a customized installation. Sysprep removes device-specific information from a Windows installation, “generalizing” the installation so it can be reused on different devices. With Sysprep, you can configure the PC to boot to audit mode, where you can make additional changes or updates to your image. Or, you can configure Windows to boot to the Out-of-Box Experience (OOBE).

To Sysprep your VM, power on the VM as shown below. This method applies to the virtualization solution you are using.
