I know you bored from this bug, So we are here to help you! Take a deep breath and look at the explanation of your problem. We have many solutions to this problem, But we recommend you to use the first method because it is tested & true method that will 100% work for you.
When enabling the Asp.net impersonation on the IIS server, the client identity could access the windows resource of the server-side with the windows account of the server-side. this is out-dated technology, there is no need to care much about it.
Feel free to let me know if there is anything I can help with.
Note: Use and implement method 1 because this method fully tested our system.
Thank you 🙂
