Is it possible to retrieve Windows Username and Email Address in ASP Pages?

Question

I've created an ASP page with forms, but I intend to
display the full name the user uses to log into Windows
(For example: "John Tan", not the username: "johntan") through a server and the email
address attached to the account (For example:
[e-mail]). Is it possible?

If I'm not wrong, for usernames would be using
request.ServerVariables("remote_user"). But what about
for retrieving of full name and email address?

Hope you can understand what I'm trying to ask. Any
help is much appreciated. Thanks in advanced.
