User's network ID in Windows 7

[aspfun]

I used code below to catch user's network login ID. It is working in XP but not working in Win 7. How to update it? (I use VS2008)

UserID = Page.User.Identity.Name.ToString

What that has to do with xp or win7?
The only complication would be if it worked on IIS6 and not in II7.

In both cases, are you debugging out of Visual Studio, or are you using something else, i.e. IIS Express, IIS etc.

In both cases, what does the UserID variable contain?
