${windows-identity} always returns "NETWORK SERVICE"

[netevang]

Has anyone had any luck configuring the log file name to be the actual logged in user via Forms Authentication (Httpcontext.Current.User.Identity.Name)? If works as expected locally, but when deployed to a remote server, "NETWORK SERVICE" is always returned (as it also is for ${aspnet-user-identity} and ${identity}). I am not sure what I need to configure. Any help would be much appreciated. Thanks.

Solved: I needed to set impersonate=true in the web.config.

Use ${aspnet-user-identity}.  windows-identity was still showing the user we created for the application to run under when connecting outside the local network.
