How does the Windows 2000 server environment use UDP and how does it fit into the TCP/IP suite?  I know it uses it for DHCP but I thought it would use TCP.  Thanks for your advance help.  I just want some clarification.

UDP is a connectionless protocol that doesn't require the kind of signalling TCP does.  If you want a reliable data path, you'll need to implement it at the application layer.

UDP allows the concept of ports to be used for a given IP address.  Network functionalities such as echo, netstat, whois, and tftp use well-known UDP ports to talk to each other.  Applications can also use UDP ports for communication.

UDP packets are encapsulated in IP packets.  You can think of UDP as a layer above IP just like TCP is.

DHCP uses UDP, by the way.
