This bug was reported on my behalf. For some reason, the bug tracker
didn't get my last email.
I've attached my config files for you to review.
Recently Windows 7 has intermittently been able to get a lease, which
is very strange.
System:
Intel Atom D510 (1.6GHz) with 4GB RAM
Debian squeeze (x64)
DHCP 4.2.0-P2 (manually updated)
