Hello Sri_1,
Thank you for your reply.
I'm sorry to hear that the logs did not provide the information you were looking for. Unfortunately, without access to additional data sources or logs, it may be difficult to determine who made the changes to your Resource Authorization Policies. However, you could try reaching out to your IT department or system administrator for assistance. If they are able to provide the time period during which the issue occurred who has ever logged in or connected.
It is recommended that you enable auditing on the RD Gateway server in the future, so that you can view the audit log to see who made changes to the resource authorization policy.
Best Regards,
Haijian Shan
