Getting Local System's UserName in a web based project

[NawazAhmed]

Hi,
I was trying to get local system's username in my code behind. I tried every almost possible way.
Here is the scenario:
My project is web based and I don't have a login screen....I need to get the local system's username when some user opens the website....
I tried.

environment.Username
environ("username")
System.Windows.Forms.SystemInformation.UserName
system.Security.Principal.WindowsIdentity.GetCurrent.Name

and some functions as well posted at this site: http://www.developerfusion.co.uk/show/4409/
But no luck.....Its getting the username from the server instead of the user's computer.....
And I am using VS 2008.
I would really appriciate....I f someone can provide me a better solution for this..

Thanks.

Well, if you are using integrated windows authentication in IIS, this will get the domain user name:

Page.User.Identity.Name

But if you allow Anonymous access, you might just get the IUSR_<machinena me> account. I'm not sure what happens if you use Basic/Forms authentication.

How can I turn on windows authentication in vista ultimate?

I found this it was under programs and turn windows features on or off..

[Curtis Rutland]

I'm not sure of your whole setup. Windows authentication works against a domain.

You need to understand more about IIS authentication. Look that up. Vista uses IIS 7.

Hey I turned on the windows authentication and ran the same thing again...
but I am not getting any username....
Any guesses...what could b the problem???

Like I said, Windows authentication works against a domain. You aren't going to be able to get just anyone's local username, because you don't have access to it through the web. You need to either set up a domain, or use basic authentication. But basic authentication still refers to accounts on the server, not the client.

I atlast got this one working........ ..
I went to server and turned on windows authentication in IIS and turned off the asyncronous option.......an d thats all I need to do to get the clients username and no doubt client should be in the same domain.

Thanks for the help guyz.
