Outlook (for macOS) Notifications Stopped Working
KB ID 0001684 Problem Like most of us I spend my working day based around Outlook calendar meetings and entries, I’ve even got birthdays and anniversaries in there. So recently when the notification pop-ups stopped working, it was a potential problem. Occasionally I could hear the notification ‘sound’, but I had to open outlook and change to the notification window to see them. When you are as absent minded as me,...
Remove and Reinstall Microsoft WSUS
KB ID 0001679 Problem I don’t like WSUS, the product is OK (ish) the problem with it is, every time it’s deployed, typically the person it was deployed for never looks after it, or manages it properly, and months/years later it becomes a massive ‘bag of spanners’, which is never the client’s fault, it’s always the poor guy who built it, or the support company’s fault. If you run WSUS, log into...

Windows Server: Disabling SSL 3.0, TLS 1.0, and TLS 1.1
KB ID 0001675 What are these protocols? Both SSL and TLS are cryptographic protocols designed to secure communications over a network (remember the internet is just a network). Originally we had SSL version 1 and version 2. But they were, (to be honest) ‘a bit bobbins’ and full of security holes, so never really took off. Version 3 however did and was widely supported. The problem with version 3 was, (again) that was also ‘bobbins’....

vSphere: Get ESX Server Serial Numbers
KB ID 0001670 Problem A few weeks ago I needed to sort out some extended warranty for a customers servers. To do that I needed the serial numbers of those servers, (a mixture of IBM/Lenovo and Dell Servers).

Microsoft Teams: Custom Background Images
KB ID 0001669 Problem With the current lockdown and everyone working from home, I’m using Teams a lot. I use one of the images that I use here at PNL as one of the background images that ‘appear’ behind me when I’m using the webcam in Teams. I was asked today how I did that, so I thought I’d write it up here. Solution I’m using Teams on my MacBook but the procedure it pretty much the same in...
