I'm already reading the thread.

I know, you just hadn't had chance to read and respond to the latest details. I didn't want the OP reinstalling Win2k til you had had time to read the latest posts.

The only thing that I can think of is that the Receiver is sending the packet, but it's being dropped by the router. However, this makes very little sense, since Ethereal (presumably running on the host Win2k box) is seeing the DHCP packets.

Could we recap the OP's network topology? Maybe there's something important that I'm missing.

As I understand it things are real simple:

-1 receiver
-1 Win2k PC (with Zone Alarm, but turned off in these tests)
-1 LinkSys WiFi switch/router (but in these tests the PC and Receiver are both just plugged into the switch)

Router is using 192.168.1.0
PC using 192.168.1.100
Receiver given 192.168.1.101

Netmask on PC and Receiver 255.255.255.0, don't know about the router but I assume that is also 255.255.255.0

Not a setup that should really be causing a problems.
