I have two questions...

1) I have noticed on some web sites that if you start a certain number of downloads at once you cannot start more or even browse the site until downloads have finished. I am assuming this is because there is some kind of limit on concurrent connections by visitor/IP/etc. How is this done?

2) When using Windows operating systems to share files across a network, what are the connection limits for Windows 98, Windows ME, Windows 2000 Professional, Windows 2000 Advanced Server, and Windows XP Professional? Are there any such limits when using IIS or Windows 2000's other server features?
