VS asking me to log in

I'm fairly new, but getting things figured out.
Why does it ask me to log in every time I do "view in browser"?
Thanks for reading.

Hi, its not clear what is asking you to log in?
Is it your application, if so do you have forms authentication set up for the directory containing your app?
There is an issue with VS2005 beta and the firefox browser which results in similar behaviour

It's a popup, and when I put my computer user name in it, it works, so I'm assuming it's IIS login, through the application accessing the wwwroot folder that my app is in.

Sometimes I login every time I need to "view in browser" and sometimes it seems to hold the login and doesn't require me to log back in.

I apologize if none of that makes sense, I am new to visual studio as well as asp.net.
