I did wonder this, but I've checked both my Linux laptop and the Win7 client
and neither have an active firewall.
Greg's diagnosis may not be strictly true, depending on what the DHCP client
logs.
In particular, I do not see an DHCPOFFER packets from the server in those logs;
maybe the server does not issue dynamic leases (generates an address for
anyone) and only issues fixed leases (for explicit known hosts in the config
file).
1: Examine the server dhcpd.conf to see if it has a dynamic range of addresses
for DHCP, or just a fixed explicit set of host configs.
2: Run tcpdump on laptop and server, see what actualy packets are going in/out,
rather than relying on the log files to recite everything.
