Most notably, after the certificate on your Front End server is renewed, make sure that ALL servers within your Lync environment are trusting the newly renewed Front End certificate.
This would be the following servers/roles:
- Lync Edge
- Lync Mediation
- Exchange CAS/UM
Once certificate renewal/assignment is complete, the last item to-be performed would be restarting the Front End Lync services by issusing the following commands:
Stop-CSWindowsService
This will take some time to complete, then issue:
Start-CSWindowsService
I have seen instances where the services will fail to stop/start, if this happens to you then you will need to resort to restarting the entire server.
Ok guys, I just wanted to touch base on this subject, as it seems it is a common mistake many people are making. Any questions, feel free to ask.
