Hi,
We have a standalone server which is not federated to Portal. The server was working fine till yesterday night and today when we are trying to open the server manager/ rest end points the server is not accessible. We had a scheduled Windows update done on the server.
Today when we are trying to access server manager/rest end points, we are getting the error as-
We have checked logs. It says RMI Registry is not running on port '1099'. And most errors relate to java.rmi.
Below is some part of the log we have checked.

We have also observed that every single time we start the ArcGIS Server in services.msc the ArcSOC.exe appears and disappears (gets killed) immediately on task manager.
Question:
Can anyone help us with this.
Thank you!
I would contact technical support and work with them on this.
Were there any other updates pushed to the machine like: anti-virus / reporting / other security tools?
Hi George, Thank you for your response.
No other updates were done on the machine apart from Windows update. We will contact technical support and check it.
