Hi,
We have 3 RDS servers and this is the 2nd time this issue has been happening. We have these servers setup since February 2015 and we never had this problem until this summer.
Last month, users were not longer able to connect to 1 of the 3 RDS servers and was caused by the fact that the RDP certificate had expired so my co-worker remove it, restarted the Remote Desktop Connection service and everything worked fine.

Today, this happened again with another RDS server.
What is the best way to fix this ? I definitely don't want to fix this again in 6 months and I refuse to believe that the best solution would be to do a script that will delete the certificate each 5-6 months and restart the Remote Desktop Connection service at night.
