Aveva License Server 2020 issue

I'm pretty sure that it is part of the License Manager web application.

Do you have the License Manager configured to manage a remote license server, one that it perhaps cannot reach?

You are absolutely right! my primary license server is SCADASERVER1 for some reason  has stopped

Sorry Rickard, I am not letting you off the hook just yet tried to start the license server  and get this. What do u suggest as next step to debug this? Not able to restart this computer so easily without shutting the whole SCADA down.

I almost got away! 

I'm not sure what could be behind that issue and you may need to look closer at logs on the license server node (both AVEVA logs and Windows logs). My experience of services suddenly refusing to start is that it is often related to changes to permissions which could have happened directly on the service account or indirectly through group policy changes.

It seems the Core service does not have any dependencies to other services, so nothing to follow there.
