ActiveDirectory rendered unusable? How to share a DSL internet connection?

Hi All,

I'm trying to share a DSL broadband internet connection in a Win2K server
environment, but I have run into problems:

* I have a wireless switch/router that can share internet connections
(Linksys WRT54G) where the DSL modem is plugged in.
* The clients (Win95 and 98 mostly) have trouble connecting to the local
network or the internet, because the DHCP server that responds first (the
ISP's or the Win2K box) assigns the IP to the client thus: 1) either
assigning an IP that works with the local network but cuts off internet
access or 2) the opposite.
* I could make the client computers use the ISP's DHCP and DNS, but that
goes against MS recommendations, and I think renders AD unusable.
* I suggest that a proxy server must be purchased, but the customer (owner
and genius behind this unusual network) says that he'll not accept this
solution (which I think is the best and only choice to make everything
work).

What can I do? Please help!

If you want to use ICS you need to disable the DHCP server on the router,
and setup DHCP on the Win2k Server. You must use the 192.168.0.0/24 range,
and the server must be 192.168.0.1. All internal clients must point to the
DC (192.168.0.1?) for DNS for AD to function. A proxy server is a good idea
but not essential.

Why can't you assign static IP addresses to all computers? I am assuming
it's not a lot of computers since they are sharing a DSL connection and a
consumer router.
 
Hi Paul,

Thanks for your answer. ICS does not work with Windows95, so that's not an
option (already tried to install it, but didn't work)

I don't know how this internet sharing router works, so I can't tell if once
it's connected it will try to feed the clients DHCP and DNS setting from the
ISP, which would ruin everything for the few WinXP laptops management has.

I can only think of a proxy server as a solution to this problem, so I guess
management will have to look thinks my way...

What do you think?
 
What if I turn off DDNS and DHCP? Would it be impossible for Win2K/XP
computers to join the domain and access shares and stuff?

Please help?

What do you mean "ICS does not work with Windows95"?

DDNS isn't actually needed, but makes things very difficult without it. DHCP
isn't needed at all - it just simplifies things (although the DHCP *client*
is needed on DCs so that they can register their SRV records dynamically in
DNS).

If the router is providing DHCP, I would personally turn that off and
configure it in Win2k. I'd not dream of turning DDNS off. Without DNS, AD
will not function; period. Your AD needs DNS like your body needs blood.
DDNS is basically a must.

ISA server would be handy, but isn't needed.

Also, I'm not sure if your comment about Win95 and ICS is correct, and if it
is, we're not talking about running ICS through 95, but having 95 as an ICS
client. The Win2000 server should provide the ICS. I would configure this
manually (basically, make the server 192.168.0.1, and make it a DNS server,
and also configure it as a DHCP server with a scope of, for example,
192.168.0.10-200).

Post back if you need more info.
