Server Evaluation Extending & Converting KB ID 0001879 Problem If you download and install Windows Server evaluation, you get 180 days grace to upgrade it to a full licensed version. Now the internet is awash with articles telling you how you can extend that – In fact you can extend it by 180 days a further SIX TIMES.

Windows Connect to NFS Share
Windows Connect to NFS Share KB ID 0001861 Problem I have an old Buffalo NAS box I use on my test network, its shared between some Windows servers and is also used by my vSphere ESX deployment as a datastore. I replaced my main admin server which had a drive mapped to the device and ‘forget’ how I’d mapped the drive originally, so it took me a while to work it out again.

Windows 11 Unsupported CPU
Unsupported CPU KB ID 0001878 Problem I needed to upgrade a Windows 11 VM from 21H2 to 23H2, as is recommended I installed the PC Health Check, I was surprised to see this error.

Stop Mac Screen Dim When on Battery
Mac Screen Dim KB ID 0001876 Problem I work primarily on a macbook, (it’s usually perched on my lap while I work). My current (and my first) macbook had magsafe charging, which is a nice feature, but when you work with a laptop on your knee you are constantly knocking the magsafe charger, which results in an annoying ‘I’m NOT charging, and now I AM charging again’ noise (I can cope with). But as soon as it’s...
VMware vSphere Adding vTPM
vTPM KB ID 0001875 Problem I’ve been asked about this a couple of times in the past, back then my test bench was running a mix of ESX 6.7 and 6.5 so I could not test and document the process. Now Everything is running ESX 8.x I can test the procedure in anger. The reason is because I was met with this today. TPM 2.0 must be supported and enabled on this PC So what’s a TPM, and a vTPM and why is that important? Trusted...
What is Latency?
What is Latency? KB ID 0001874 What is Latency? I hear people use the word ‘Latency’ a lot, mostly without ever really understanding what it is, unlike its close relations bandwidth and thoughput* which are measurments of data, latency is a measurment of TIME, and in a lot scenarios is variable depending on what’s happening. *Note: Too low bandwidth and thoughput can increase latency. There will always be latency,...

Proxmox HA Cluster
Proxmox HA Cluster KB ID 0001872 Problem Proxmox HA Cluster: As the name implies this allows the cluster to ‘restart’ failed virtual machines on another host in the cluster in the event of a host failure. Unlike VMware (that has a vCenter appliance to do this) in Proxmox it can be configured from any host. Which may seem like an advantage – but the GUI can get a little ‘clunky’ whilst configuring HA....
