Dual Nic on Vista Business - Help Needed

I've set up a computer network with the standard two nic system I had used on
XP on Vista Business. The Server and the clients are all running Vista
Business. The Server has two 1gm Nvida Etnernet cards built into the mother
board. The Server is connected to the internet through Lan 1 with the router
being set to 192.168.1.1 and the ethernet set to obtain its addres from the
router using DHCP. Lan 1 is setup for Internet Sharing. Lan 2 is set to
192.168.0.1 with the clients set to static IP addresses and using the Lan 2
address as the default gateway and DNS. The DNS suffix is set to mshome.net.
The clients, NAS and network printer are connected together with the server
through a 1gb switch on Lan 2.
This setup worked fine under XP, but under Vista Business, the clients keep
loosing internet access. I also noticed that Vista keeps changing the statis
of Lan 2 from Private to Public.
I'm hoping this something simple I missed because the fix is to reboot the
server, then the clients can access the internet again.
Any suggestions would be greatly appreciated.
 
We have some issues with this configuration.

1. The server should use static IP.
2. I would setup DHCP on the server.
3. It is better to setup DNS on the server

Robert,

Thanks for your prompt response. I'm not sure which nic you're referring to??

Are you suggesting that I set Lan 1 to 192.168.1.1, the same address as the
lan side of the router??

Lan 2 has a static IP address of 192.168.0.1 and that address is set for DNS
 
Robert,

I've changed the IP address for Lan 1 to 198.168.1.10. The problem with
disabling the DHCP in the router is that the second port on the router is
managing 3 phone adapters and the router is providing IP addresses to the
adapters.

Hopefully, the static ip on Lan 1 will help resolve the problem.

Robert,

Thank you. I don't know why I didn't think of setting LAN1 to a static IP
address because I've mixed static and dynamic Ip address on a network before

Your suggestion defenitely helped.
