Hello,
Im using this to show the name of the user
protected void Page_Load(object sender, EventArgs e) { txtNombre.Text = System.DirectoryServices.AccountManagement.UserPrincipal.Current.DisplayName; }
but when I published it I get the error "Unable to cast object of type 'System.DirectoryServices.AccountManagement.GroupPrincipal' to type 'System.DirectoryServices.AccountManagement.UserPrincipal'."
The server has already the windows authentification activated and the web.config is
<authentication mode="Windows"/>
how Can I solve this?

It looks like you've configured OWIN Identity? You'll need to turn off the Cookie Authentication if you wish to use Windows Authentication.
On a side this, Word Interop...
<add assembly="Microsoft.Office.Interop.Word, Version=15.0.0.0, Culture=neutral, PublicKeyToken=71E9BCE111E9429C"/>
... is not recommend for use on a web server.

The correct construct is for a web application is.
HttpContext.Current.User.Identity.Name

Usually indicates anonymous authentication is enabled in IIS. Disable Anonymous Authentication.

Usually caused by a redirect to a login page configured in the web.config. Windows authentication does not require a login page. IIS (and the browser) handle the user authentication behind the scenes.
What are you trying to do exactly?

I don´t have any login Page, how Can I see this?
and I´m developing an Intranet so the page must get the name of the user for their requirements

Look in the web.config and/or make sure Forms Authentication is disabled in IIS.
If that does not work try adding the following to the web.config.
<system.webServer> <modules runAllManagedModulesForAllRequests="true> <remove name="FormsAuthentication /> </modules> </system.webServer>
