How to get Windows user name when identity impersonate="true" in asp.net?
I'm creating an intranet asp.net mvc application that everyone in the company should have access to. I need to run the website impersonated for database access etc., but I want to know who each user is.
When I look at Page.User.Identity.Name it's blank. Is it possible to get the user's windows account name even though the site is running impersonated?
Edit: Here's a little more info. I have a site in IIS 6 running with anonymous access enabled. The site is running under a system account that has access to the database (because all of the employees do not have access to the database).
My web.config has <authentication mode="Windows" /> and <identity impersonate="true"/>
My goal is that the users won't have to log in - that fact that they are logged into our network (and the fact that the site is not on an external IP) is enough authentication. I would just like to know who the user is in order to track changes they make, etc.

With <authentication mode="Windows"/> in your application and Anonymous access enabled in IIS, you will see the following results:
System.Environment.UserName: Computer Name
Page.User.Identity.Name: Blank
System.Security.Principal.WindowsIdentity.GetCurrent().Name: Computer Name
With <authentication mode="Windows"/> in your application, and ‘Anonymous access’ disabled and only ‘Integrated Windows Authentication’ in IIS, you will see the following results:
System.Environment.UserName: ASPNET (user account used to run ASP.NET service)
Page.User.Identity.Name: Domain\ Windows Account Name
System.Security.Principal.WindowsIdentity.GetCurrent().Name: Computer Name\ASPNET
With <authentication mode="Windows"/> and <identity impersonate ="true"/> in your application, and ‘Anonymous access’ disabled and only ‘Integrated Windows Authentication’ in IIS, you will see the following results:
System.Environment.UserName: Windows Account Name
Page.User.Identity.Name: Domain\ Windows Account Name
System.Security.Principal.WindowsIdentity.GetCurrent().Name: Domain\ Windows Account Name
