One Liner: Add Trusted Root Cert Authorities to Edge Servers

September 19th, 2015 2 comments

Chris Hayward (@WeakestLync) wrote a great blog post with a neat & easy way to add trusted root certificates for your edge servers. Of course, everything in Lync and Skype for Business uses certificates, so ensuring you have all of the certificates is crucial for federation with other organizations.

Once I saw Chris’s method, I, of course, thought that PowerShell could do this as well. Voila, a one-liner to do it. This example uses the same list from Chris’s blog post, and suppresses the output so you can use it your provisioning scripts.

"", "", "", "", "", "", "", "", "" | ForEach-Object {Invoke-WebRequest -Uri $_ | Out-Null}

This method essentially just cycles through each item in the array, and does a web request for each. As each web request is completed, any new certificates are automatically added to the trusted root cert store. Usually, some of these already exist, so don’t be surprised if the total certificate count doesn’t increase by the same number of items in the array.
