In Place Upgrade Windows 2016 to Windows 2019
KB ID 0001761 Problem For the last twenty years or so I’ve said “In place upgrades are a bad idea”, my rationale has been that if something is broken we are simply migrating that problem, and we are relying on a lot of factors, (some of which may be unknown.) That we will just have to ‘trust that it will work’. Most modern servers are virtual so we can snapshot them, or clone them and test the upgrade...
Remote Desktop Services: RDS Sizing Calculations
KB ID 0001753 Problem This is a horrible subject to find any decent information on. Microsoft are typically ‘vague’ and most people are stuck with using trial and error, or massively overestimating hardware to be on the safe side. I get asked this occasionally and, just like Microsoft, it’s a question I don’t like to answer! People are reticent to tell you that you need ‘x’ amount of CPU and...

Now traditionally I’d use RoboCopy or XCopy to migrate files and folders, and for ‘User Profiles’ I would normally back them up, and restore them to the new server. This is because the file permissions on ‘correctly...
Domain Join SID Error
KB ID 0001732 Problem Thankfully I don’t see a SID error very often these days; The following error occurred when attempting to join the domain ‘{domain-name} The domain join cannot be completed because the SID of the domain you attempted to join was identical to the SID of this machine. This is a symptom of an improperly cloned operating system install. You should run Sysprep on this machine in order to generate a new...
The Web Site for the CA Must be Configured to use HTTPS
KB ID 0000838 Problem When attempting to contact a server running the Certification Authority Web Enrolment role, you may see the following error. In order to complete certificate enrolment, the Web site for the CA must be configured to use HTTPS authentication Solution The correct fix is to set the web server (IIS) to serve the certificate website securely using https, though you can just set Internet explorer to ‘work’...
