Report Server Error: "The request failed with HTTP status 401: Unauthorized

Hello,

I am getting this error when I am running SQL Server Report.

The service account is Admin and able to open manually from the browser but when I am running from ESP or command prompt I am getting error "HTTP status 401: Unauthorized".

Other user is able to execute this report, I am not able to understand what is the issue with the service account.

Window Server version :2003

Could you please give suggestion, what I can do here.

Thanks

Sandeep
