Hi,
I get a "Server is not operational" error when configuring my first ADFS. OS is windows 2016 server. I already did some research in google. Some forums say its host firewall, some say check the service account, some say the SQL service account and some other stuff. But none of if solved my problem.
We need more specific to be able to help you out. Like the full error message you see on the screen (maybe a screenshot), the error messages you see in the event logs as well as some more details on the deployment type you are having.
I just found out what was causing the error. We have multiple DCs and the DC this machine is reporting to has no problems with the ports. The problem was the ports going to other DCs especially the one containing the fsmo role.
