The difference between console application and web service is that console is running with user account and web service is with service account. So, current user of the service is NT AUTHORITY\SYSTEM because it is a service. The service itself does
not have any direct access to the user logged.
This forum is for ASP.NET. However you can at least indicate here why service needs to get the name of user.
