I think this is the most appropriate group, so here goes.

Recently I added a Windows 2000 Server into my network,
which previously had a Windows 2000 Pro machine sharing an
ADSL Dial-Up connection (I have to dial in to the modem,
not the network). The server was configured in an isolated
environment with no other PCs connected, using default
settings. However, no other computer on the network
(including complete rebuilds) will recognise it as a DNS
server or a DHCP server, with the end result that nothing
recieves IPs from the pool (10.10.x.x), plus I cannot
share any internet connection. However, all machines can
find and join the domain quite happily.

I would appreciate any thoughts.
Thanks,
Nick Jackson
 
If they're not obtaining IP addresses then obviously none of the TCP/IP
based services (ie DNS or ICS) will work. Have you authorized your DHCP
server in the domain?
 
As far as I can tell everything expects the ICS to be at the default gateway
IP of 192.168.0.1, however the DHCP has a pool of 10.10.0.1 to 10.10.0.254
with a mask of 255.255.0.0
 
I think the problem is that ICS has its own DHCP server.
So may be the two servers are overlapping. Just disable
your DHCP server or use NAT (not ICS) with no DHCP option.
If you use NAT with no DHCP - you can use DHCP server.
 
When you set your server's internet-connected
NIC's "sharing" tab to ENABLE Internet Connection Sharing
(ICS), your LAN Server NIC's IP settings are automatically
set to an IP address of 192.198.0.1

If your client computer won't automatically seek the
server's IP (using the dynamic settings), try using the
Static IP settings: on yhour client computer go to Network
places /properties /Internet Protocol
TCP/IP) /properties /General tab and set to "Use the
following IP address." Put in IP address 192.168.0.n (n is
the number of your client, e.g., 2 if it's the 2nd
computer), put in subnet mask 255.255.255.0, put in
default gateway of 192.168.0.1, and then put in preferred
DNS server 192.168.0.1

That's how I got my ICS to work. In all due humility, I am
still a work in progress re W2K -- haven't been able to
get my client computer to access the server even though
the computers can see each other in "My Network Places."

If you can make NAT work on a USB ADSL modem be my guest :-D

Thanks for the info on ICS running its own DHCP - should make life easier.
