Hi Experts

Is this the best way to get the name of a user using an app on any machine?....

Label lblUsername = new Label();
lblUsername.Text = System.Security.Principal.WindowsIdentity.GetCurrent().Name;

im then inserting this data with other info into db.

Thanks

That would suggest that you are talking about a Web Application rather than a Desktop app. You must have anonymous access enabled for your site, which is causing the Identity of the account that IIS runs under to be returned, rather than the domain account that is accessing the site.

In IIS Admin, you need to switch off the Allow Anonymous Access option for the site.

I agree with carl, you must use Window Authentication instead of Anonymous access.

If this is a web app just use :

User.Identity.Name

Open in new window

Hi Guys

I have tried all 3 of these and still no luck. What appears in db table sis below...

User.Identity.Name; = empty
System.Environment.UserName; = IUSR_SR-PNG-WIP02
System.Security.Principal.WindowsIdentity.GetCurrent().Name; = IUSR_SR-PNG-WIP02

Thanks

IUSR_%computerName% is the users IIS uses for anonymous users.  If you want to capture the user name you need to enable impersonation.

Impersonate the IIS Authenticated Account or User:

To impersonate the Microsoft Internet Information Services (IIS) authenticating user on every request for every page in an ASP.NET application, you must include an <identity> tag in the Web.config file of this application and set the impersonate attribute to true. For example:
<identity impersonate="true" />

It seems that you have this set on your dev machine but not in production.
