I have an old Canon MF5650 printer connected to a Windows Server 2016 as a network printer. It was already a challenge to find a working x64 Windows driver, let alone a driver for macOS.
Fortunately, macOS supports printing to PDF file natively, and copying that PDF file to a Windows computer and printing it from there can be automated.

Every computer joined to an Active Directory domain has its own special account in AD, meaning each computer actually has a “username” and a password of its own. The username is the computer name followed by a dollar sign ($). The password is automatically negotiated between computer and domain controller when you join the computer to AD and is renegotiated on a periodic basis thereafter. This password is called machine password.
For this or other reason, sometimes one needs to revert a member computer (or an AD) to a previous state in time. If computer and AD changed machine password meanwhile, and you restored only one of them to the state before that, passwords are out of sync. Users can no longer log in on that computer.

I was looking for a way to automate remote Linux computer shutdown requiring minimum permissions. This is what I came up with.
The procedure describes how to configure and prepare Fedora’s built-in shutdown user account and trigger a shutdown from a Windows computer.

A successful configuration of Samba and Winbind allowing users to login to a Linux virtual computer using ones Active Directory credentials might stop working after a few weeks. If the virtual computer was reverted to previous snapshot between machine password changes in AD, the AD controllers will not let the computer authenticate again due to machine password mismatch.

VMware Tools is a set of drivers and utilities to make a virtual computer perform better and faster inside a virtual hosted environment. It makes a virtual computer aware of its host at least to some degree.
Once I managed to install the VMware Tools on a Linux based virtual computer properly, I have decided to write it down for good.
