ICS is technically working, but I must not understand something.....

[Matt]

I have a constant connection to the internet and a
Windows 2000 server at the front end of my house. It
serves 3 computers and I accomplish this by sharing
the main NIC card using ICS to the second. Via a hub,
the other 3 computers get an IP address from the
server and thereby internet access. Now the quirky
thing:

It's worked great for a year. Now, it keeps getting
an incorrect Gateway. Here's the IP's from the
server:

Main NIC: 65.xxx.xxx.191
ICS NIC: 192.168.0.1 (as controlled by Win2K)

My clients should, and used to, get address like:

IP: 192.168.0.50 (or something)
Subnet: 255.255.0.0
gateway: 192.168.0.1

Now however, they keep getting the following settings
with the different gateway:

IP: 192.168.0.50 (or something)
Subnet: 255.255.0.0
gateway: 65.xxx.xxx.191

You'll notice the gateway is the IP address of the
Main NIC on the server.

The problem is corrected by going to DOS and doing an
"ipconfig /release" and then a renew. But even then,
it only lasts for about 2 minutes and then it ends up
with the wrong gateway again.

Any ideas?

Thanks a ton,

Matt

ICS has its own DHCP service, and it seems you have enabled Win2K's DHCP
service as well. Turn off the latter...

This is where my ignorance will show:

by enabling ICS, Win2k automatically assigns the second NIC as a DHCP
client. Where is the other DHCP service within Win 2k and how would I
shut it down?

Thanks

It's only a theory, of course ;-)

Look under Admin Tools for a Services widget. I believe Win2K Server editions
come with a DHCP service, and if that's correct there should be an entry under
Services, most likely set to Auto start. Try setting this service to Manual
and then stop it and reboot to see if it affected anything (good or bad)...
