Deploying a ‘Nano’ Webserver (IIS)
KB ID 0001526 Problem We’ve had Server Core for a while now, and I’ve never really seen it deployed in anger. Now we have Nano Server. You don’t install this like normal Windows Server distributions, i.e. it’s not an option when you run the install DVD. Originally you have to create the image with Powershell, but now you can use ‘Nano Server Image Builder’. Nano Server is a tiny distribution, and...

Windows: Deploy and Configure DNSSEC
KB ID 0001524 Problem Like many protocols and solutions, DNS was designed in a time when we all trusted each other, and a ‘hacker’ was some sort of farm equipment. To ensure when you get a response form a DNS server it is coming from where you expect it to, and you can trust it. We use DNSSEC. Basically it signs the DNS record with a digital cypher. The client can then validate the DNS record when it receives it and it...
VMware Fusion on macOS Mojave: No Mouse or Keyboard
KB ID 0001523 Problem While building my new MacBook, I installed VMWare Fusion, (I always run a Windows VM, in case I have to do something on Windows). But no matter what version I tried to install, I could not interface with the VMs, (no mouse or keyboard). I ran Fusion 11 on my old MacBook, (running Mojave). So I was a bit confused.

Citrix: mac OSX ‘You have chosen not to trust…’
KB ID 0001520 Problem After a colleague deployed Citrix for a customer the other day, they complained that they had a mac user that was getting certificate errors. They had a publicly signed wildcard certificate, but this user was still having problems. After I heard a few “tell him to stop using a mac” comments, I said, “I’m using a MacBook here, would you like me to test it?” The URL opened fine in...

Manually Extracting VMware Tools Drivers
KB ID 0001518 Problem If you want to get hold of the actual drivers from VMware tools, e.g. to have them in a machine that you will be deploying into VMware ESX/Workstation etc, then this is how to do it. Solution I’m using WinSCP to connect to one of my ESXi servers, (it’s free, and just works!) From the root directory locate vminages and open that. Tools-isoimages, (this might seem long-winded, but if you keep an eye on...
Azure: There is Currently a Lease on the Blob
KB ID 0001517 Problem This sort of highlights my lack of experience with Azure! But I had to Google it, so if you are here, you did as well 🙂 There is currently a lease on the blob and no lease ID was specified in the request. Solution I had been uploading .vhd files and creating VMs from them, and was tidying up, so I wanted to delete anything that had been left behind.
