NT user name

hi all,
i have a iis on windows xp pro. this iis serves in
intranet. and all users have domain password in intranet.
i write some asp code for this. but this code does't give
me the nt user name of user who visit my site.

this code is only giving users who is recognized on local.
and access the page on local...

now what can do on iis's configuration.
thanks for your helps...

my code is below:

<%
Dim login,userName
Dim adres
userName = Trim("" & Request.ServerVariables("LOGON_USER"))
login = Request.ServerVariables("REMOTE_ADDR")
Response.Write "User Name: '" & userName & "'"
REsponse.End

%>

Disable anonymous access and configure
basic or windows integrated authentication.
