DHCPD and Windows question

[Todd Littlefield]

Hello,

    I have a stupid question about how to configure the ISC DHCPD to 
work with
Vista/Win7.  At home I have XP and Linux systems running.  They all will 
broadcast
out to the network to find the server and request and address/lease.

    The DHCPD server is configured to hand out the same address, based 
on MAC
to all the machines/switches/etc. that are running internally.  The 
problem comes in when someone with a laptop running Vista or Win7 comes 
over.  According to M$ they
changed their DHCP client in Vista and 7 to rely on broadcasting to get 
address.

    From digging on the network, it seems to be that the broadcast flag 
needs
to be enabled on the server side.  Otherwise when clients beacon out to 
get an
address, the server doesn't respond to it.  (perhaps the incorrect choice of
words for the behavior)


    I've dug through the ISC docs for the daemon.  I thought the 
always-broadcast command would do it...  Unfortunately that is not the 
case.  There didn't seem to
be anything in the GNHLUG email archives about this problem.

    If I disable the daemon on the server and use the one on the router, 
the Windows
boxes are happy...  But that makes me unhappy.  I'm at my wits end 
trying to get it
figured out.


    The server in question is running CentOS 5.4 with dhcp-3.0.5-21 
running.  The running config is attached.  I'm sure I there are multiple 
things that could be set up better but it passes parsing and works, at 
least until someone visits.


    Any and all help is greatly appreciated.  Thanks in advance!
