User ASP.NET runs under

by

In summary:

  • IIS 5.1 (Windows XP) – it’s a local ASPNET account
  • IIS 6 – by default, application pools run under the Network Service account which is a member of IIS_WPG group
  • IIS 7.0 – still Network Service
  • IIS 7 SP2 / 7.5 – runs under an ephemeral thing called ApplicationPoolIdentity which maps to an account IIS APPPOOL\ApplicationPool (e.g. IIS APPPOOL\DefaultAppPool). This account is a member of IIS_IUSRS user group
  • ASP.NET Web Development Server (Cassini) – it’s obviously your own account

And it’s a good practice to create a custom low-privileged account to run your application especially on PROD environment or when you need to access the network from the application.
