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!

 

Tim.
