Shelly has been making some great products that can be integrated into Homeassistant. Now generally they work fine with Homeassistant out of the box, but I wanted to run a firmware that I knew what was going on in the background and did not phone home for any reason. I as a rule block outbound to the internet traffic for my IOT devices, there is no reason they should be accessible from or to th...

I have been overhauling the auditing using Netwrix Auditor. There are a lot of changes that have to be made to a corporate environment to accommodate all of the changes that are to be audited. Several of the things can be done via group policy. The group policies are documented well enough by Netwrix. The part that came to a quick slow down when Netwrix requires a change to the audit permis...

Some of the goals of the exercise was to add some automation to a task sequence and also speed up the results so that to not hinder the technicians that do the deployments.
We wanted to add bit-locker encryption to the task sequence, with full disk encryption to add security to reused disks for re-images. SCCM support for FVE (Full Volume encryption) was just added in 1806. Through tes...

When setting up or maintaining multiple AD domains, due to legacy environments. It is not wise to point the DNS servers of the new domain to the old servers.
I recently discovered this done on a 1700 user AD environment. There was a constant slow to resolve DNS when browsing the web. The internet connectivity on location was a 500/500 fiber with modern firewalls. Needless to say it was...

During testing of using Skype for business for Audio/Video conferencing all was going well, until enabling desktop sharing. When ever anyone in the group (all on LAN to each other) we would start a storm of disconnects from Skype.
While troubleshooting the problem, it was noticed that the person who initiated the desktop sharing would get a very brief, about 2-3 second drop from the in...
