I am working on migrating my organisation's existing ArcGIS Server 10.3.1 site to ArcGIS Enterprise 10.5. This entails using creating an internal facing portal and ArcGIS Server site for the organisation's internal data and an external portal and ArcGIS Server site for our external facing customers. Overall, I have been really impressed with how ArcGIS Enterprise handles permissions and security.
My problem is this: whenever the ArcGIS Server Service is restarted on our External ArcGIS Server site the sharing is reset for all of the content. This results in public applications being unavailable and users not being able to access content shared to them. I have had to manually reconfigure all the sharing in ArcGIS Server manager on several occasions, which is time consuming.
Has anyone else had this problem? Is there any way to ensure that content sharing does not get reset when ArcGIS Server is restarted?
