Here's a timeline of a client getting a DHCP-assigned IP address.

It starts with a DHCPDISCOVER broadcasted packet that multiple DHCP
servers might hear and respond to with a DHCPOFFER response.

The client selects one and sends a DHCPREQUEST, which the server
acknowledges with a DHCPACK.

<pre>
Client (UDP port 68) --- DHCPDISCOVER ---> (port 67)  Broadcasted to everybody
Client (UDP port 68) <-- DHCPOFFER ------- (port 67) DHCP Server(s)
Client (UDP port 68) --- DHCPREQUEST ----> (port 67) To selected DHCP Server
Client <-- DHCPACK ---------  DHCP Server
</pre>

To gracefully shutdown the client, the client releases its IP address
with a DHCPRELEASE packet to the DHCP server.

  The San Jose DHCP server is tiger at 10.224.88.238.

------------------------------------------------------------------------------
To manage the DHCP configuration, 
  -- use the "Client Connection Manager" to get a console connection to tiger,
  -- the password is =adapter,

After that, there are 2 ways to get to the DHCP management screens, either
  -- open up the "Computer Management" icon from the desktop (compmgmt),
  -- expand the "Services and Applications"
  -- expand "DHCP"
  -- expand the "Scope [10.224.88.0] San Jose-Thomson" folder,

or
  -- lauch mmc ("Microsoft Management Console")
  -- "Console" -> "Open" -> "dhcpmgmt" (= \winnt\system32\dhcpmgmt)

------------------------------------------------------------------------------
There is one "Scope" and that's for the San Jose office network, 10.224.88.x.
   (There used to be a second "Scope" for the old 10.24.x.y 
          network, but I removed it on 9-15-2004.)

The details are
