Two nic's one static, one dynamic ip on Win NT 4 server
Hi everyone,
I have a problem involving two network cards in one win NT4 sp6 server.
The situation is this:
One networkcard is for my internal LAN having a fixed ip adres in the range of 192.168 ..... The server is running DHCP, PROXY and so on for four client machines .....
The second networkcard is for the ADSL connection with my provider ....
The problem:
The service provider gives me my dynamic ip adress via a copperjet 810 modem, running in bridge mode. So the second network card should be set to "obtain IP from a DHCP server" (i think) ...... this option can not be set ......
The question:
What should be changed in the configuartion to set one nic to static ip ..... and the other one to dynamic ip .....

If I remember well in Windows NT, when you select IP protocol properties you can select also the network adapter for witch you specify this value. just select the adapter for internal network, specify the IP parameters, and then select adapter for ADSL and select "Obtain .."
I don't think NT4 allowed any interface of a DHCP server to have a dynamic address although there may be a trick of unbinding the DHCP service from the NIC you want to set to obtain a dynamic address.
As it's only 4 clients why not just configure them with static settings and remove the DHCP service, then you will be able to set the interface to obtain a dynamic address.
Really you ought to have a firewall in between the server and the internet (which would solve the problem since you wouldn't need a dynamic address for the DHCP server), at the very least unbind wins client from the NIC that connects to the modem.

Okee .... thanks for the comments but ......
Some more info:
I tried stopping the DHCP-service but this still did not give me the option to set the "Obtain ......." setting for the ADSL-NIC
Also I tried un-binding the DHCP-service for this NIC .... no effect ......
By removing the DHCP service you mean stopping it or de-installing it? ......

I think you have to completely uninstall it.

Thanks JP .... that last line about "one NIC on DHCP and one not" clear-up my question some what ......
But what about one NIC on a DHCP service running on my own internal network and one NIC on a DHCP service, provided by my ISP ......

Simple solution is - leave everything on DHCP, but create a DHCP scope with only one address in it, and reserve that address for your server - this will ensure that the server always gets the same address from DHCP - when you add the reservation, you need to plug in the MAC address for the internal card.
You could start using DHCP for the whole network by just creating a bigger scope, but still reserving the one address for the server.
HTH,
