如何知道哪个Lan用户是在我的Intranet上？

If you have disabled Anonymous access, then you should be able to retrieve the value from: Note that IE is required to support Challenge/Response (IIS4) or Integrated Windows Security (IIS5). If you can't disable Anonymous access, and/or need to support Netscape, then there is a possible alternative, provided you're not using DHCP. If your users have static IP addresses, you could store their usernames in a table and do a lookup against their IP: If you can't enforce either of those things, then you may have to resort to forcing your users to log in (even only once, then storing a cookie). I suppose this depends on balancing the importance of knowing who is on the site versus every user having to log in.
