On Windows Domain I know the default user name format is domain\username. But on workgroup I ma little confused. For example, running a .NET application on development server gives me, my app is running under computer-name\myname user and running same app on IIS gives me IIS APPPOOL\ASP.NET v4.0. So, how should I read this format?
The part before the backslash can be one of three things:
'NT SERVICE\myservicename' is used to run a Windows service under a unique account, same with 'IIS APPPOOL\AppPoolName' which is used to run a single IIS application pool and separate its permission from any other pools. You have to type them in.
So your app is running under two different user accounts, that's all.
