Tim,
You
can't have two DHCP servers on the same "wire"... Each client machine will
simply broadcast a "here I am- can I have an IP address, please" request,
and
listen to which ever DHCP server responds FIRST.
I
see
a few solutions, all of which involve segregating the network into 2, and
running different IP address ranges on each.
The
problem comes if you're using Windows Internet Connection Sharing on both.
Unless it's changed in XP, you can't specifiy the DHCP range it chooses to
hand
out :-(
Personally, I'd keep your network wireless, and their network wired.
Then
have one ADSL-Sharing box per media type :-)
In
order to administer their machines, you'd simply take out the wireless
card, and
plug YOUR laptop into the CAT5 :-) :-)
If
both networks are wired, then, again, plug into a different wall point
(this is
why you install them in blocks of 4 :-), and refresh your DHCP-given
address.)
Alternatively, I'd "suck it and see"
performance-wise, whether both networks can share the same ADSL line. I
think it
likely that they WILL be able to....
Regards,
Mark
I’m trying to plan the
network for
the new place, and keep going round in circles and disappearing up my own
arsehole J Things are very simple here at
the moment, but both bandwidth requirements plus the number of connected
devices will increase dramatically.
Currently I have an ADSL
connection, with a “server” running Windows XP. This has a
wireless LAN card
installed, and using Windows ICS acts as a DHCP server, and internet
gateway
for my laptop and iPAQ, plus the family’s single PC (again over the
wireless
network)
Now things start to get
complicated. We don’t want to rely on the fact that a wireless
network might
(or might not) work in the new place. There is some existing
“infrastructure
cabling” that we might be able to utilise for computer
networking.
I want to retain my existing
system more or less intact – ADSL plus wireless
network.
The family will have at least
three PCs which will need networking together, plus there will be an
additional three machines which belong to a small business which is
co-located
with us for at least the first 12 months. They will need their own (shared)
ADSL connection – and I should imagine some form of DHCP
server.
All this is fairly simple (to
my
mind anyway), until you throw a spanner in. I will want to connect my PC to
the network in order to use Terminal Services (Windows XP remote desktop)
to
carry out maintenance etc. Can you have two DHCP servers on the same
network?
Is it is simple as dividing the 192.168.0.X network into two separate
sub-nets
using the network mask 255.255.255.128? How do I set up the two network
cards
in my machine (one wired, one wireless)?
HELP!
