I have 4 ArcGIS Server virtual machines (1 primary, 3 standby). All 4 are configured to use shared instances by default with Server Manager.
However, today, when I checked, 2 of the standby machines said that the default instance type is "Dedicated".
Has anyone else observed this setting changing on its own?
The only background task that touches AGS is a nightly WebGIS DR restore from the primary machine to the 3 standby ones.
System Details:
I have never seen this behavior, but my organization also doesn't utilize WebGIS DR. I suspect it is a defect related to WebGIS DR. I would run a script or scheduled task to check the setting right before and after the backup and restore processes.
