In a previous post, we published the checks/validations that we should do in the Certification Store in the Lync/SfB servers.
We decided to write a PowerShell with all these checks to make it simple to use. The script will be kept in sync with the post, meaning that when a new check is added, it will also be included in the script.
The PowerShell script is available in the TechNet Gallery:
Both script usage and change log are included in the TechNet Gallery description.
