Vista: what your mom never told you

[David W. Hankins]

Nothing to see here, just seeding the archives for googlers.

Simon sent a note to dhcwg at ietf.org today which came through in
the archives in two parts and is missing his quote from rfc2131;

So there are two things your mom never told you about Vista clients.

One is that they might set the IP source address nonzero, and this is
just fine so far as dhcpd is concerned...maybe not so fine as some
folks' firewall rules or DHCP snooping equipment is concerned.

The other is that Vista sets the 'broadcast bit' in the BOOTP header,
which informs dhcpd that it is required to answer the client in
broadcasts.  We've had some folks find their networks misdirect, drop,
or just filter out broadcasts from the DHCP server.

So if your DHCP server works with XP but not Vista, have a look at
these two things.
