Hello Everyone,
We are running into issues at 11.3, and 11.5 where clients performed the latest Windows Server 2019, 2022 patches, restarted the machines and datastore no longer validates hence "breaking" Federation. I have opened an ESRI ticket and we are seeing nothing unusual.
1. We have ensured all folders have service account access, no luck
2. We have restarted the the services and machines ( portal, datastore, server) , no luck
3. Describedatastore shows healthy status, still no luck
4. We even tried to restart a broken hosted service via portal admin end point to see if it will fix the issue, no luck
5. Ensured all ports were open, disabled firewall, still no luck
This is happening to machines both on the AWS environment and On -Premise Hyper-V boxes. Since this is a production environment, we are hoping to use the Repair Datastore as the last resort.
This is broken at 11.5 even on a machine that hasnt been updated since January so makes me thing something else is happening. Three different IT departments, three different Clients are involved. All of the machines were functional before Wednesday the 12th of November 2025.
The machines worked perfectly last Wednesday. No other changes were made except for the update patches to Windows. I monitor a few more machines that are going to get the patches applied this next weekend and am hoping to find a root cause/solution before then. I am attaching a screenshot of the updates that were applied, machines restarts and AGE is broken.

I am really running out of resources and time at this point. Any help is appreciated.
thankyou
