hey...

this one is really spinning me out...decided to format and reinstall whole network today (only small network).

I have two servers, server1 and server2

Formated server1 and installed windows 2000 server onto it, this server has two NICs...one for Broadband and one for LAN

all installs fine, but when i come to ping server1 it always looks at the external address and not the internal one...its not DNS (checked this) there for after getting very annoyed i stuck the NIC card into other server and it did exactly the same...

help...

You have 2 nics on the server, one is internet, the other is local. Don't worry about dhcp showing the internet ip. This is normal for it to show the public ip address because it IS assigned to that server. At present, the dhcp is going to listen on all the nics on that server. You just need to specify the ip address of your internal side for it to listen on ONLY (one of the dhcp settings) so it will only hand out addresses to your local side and not the internet side.

Hi!
My humble opinion is that you have to change the bindings for the NIC-s ()

Tomomark,

It sounds like you have a router that give you internet connectivity. Is this right? If this is the case, you probably do NOT need two nics. You broadband router should get an IP address from your ISP. (You probably don't need an address from your ISP seeing how you only need one connection to the internet.) [By the way, if you do NOT have a router, you will need two nics.]

So, your router gets an IP address from your ISP. Then you need to configure your router NOT to hand out DHCP addresses. You should configure a LAN address for your router...say 10.x.x.1

- Then you should configure your domain (OFF the NETWORK...without connection to the internet) Make the first DC IP address something like 10.x.x.10

- Configure DHCP to hand out addresses in the 10.x.x.20 to 10.x.x.100 range. Also configure the scope or server options to point DNS to 10.x.x.10. also configure the gateway to be the IP of the inside of you router (10.x.x.1)

- Configure your DNS server to forward DNS request to the ISP's DNS's servers. To do this, you will have to delete the "." root zone in your DNS adminstrative console.

- You should be good to go...hope this helps
