Event 18456 – Start-CsPool Error Failed to Connect to BackEnd

I hit an expected snag recently where I wasn’t able to get an existing SfB 2015 Front-End pool to start after growing it from 1 to 3 servers. Coincidentally I’d performed this same job for another customer maybe a month prior and it had gone off without a hitch. Not so this time. Try as …

Lock your SfB meeting to prevent unwanted newcomers

Hosting back-to-back meetings is at times unavoidable, and if you’re not careful you run the risk of people joining your second meeting before the first has concluded. This potentially awkward scenario arises when you’ve used the same conference ID for both, and your newcomers blissfully join not realising the virtual meeting room is already (still) …

It’s less common to see this in established installations, but there are genuine reasons why this might …
