I have a server with 2 nic cards and I want to tie 2 different
networks to the server. I want one nic to handle for instance a
192.168.x.x. which will handle incoming email while the other nice
10.x.x.x will handle a local lan. The SBS server will not be acting
as a VPN or anything else, just for access to email but more
importantly for the users on the 10 network to access sharepoint (or
the companyweb). Is this possible? Will exchange be able to handle
email being recieved on just one network from the outside? I know as
long as the DNS is right on the 10 side the users will have an problem
accessing company web. Can I still control users on the 10 network
with the domain?

What do you mean by 'handling email'? If you mean 'is connected to the Internet' either directly or otherwise, then that is the *only* Microsoft-supported two-NIC SBS topology.

First recommendation: don't use the 10. network, use another 192.168.x. network, and make x something unremarkable towards the middle of the range e.g. 85. If there are other 192.168. networks in your system, yours need to be different from all of them.

A two-NIC SBS functions as a simple firewall, so make sure you have it the right way around. Which NIC is the internal (LAN) and external (Internet) NIC will have been set during installation, so you may need to experiment a bit to find which is which. Run the Configure Email wizard, tell it what IP addresses you want on them, what the ISP's DNS servers are, your email domain name, the full public DNS name of the Internet connection, and a few other details, and it will do all the work for you. If you make a mistake, run it again, you can keep the bits that are right and just change the others. Make sure the workstations are set to pick up their IP addresses and DNS information from the server, and the SBS will sort out their TCP/IP properties.

There are more details to the whole thing, but this is broadly what is necessary. You don't say what exactly the 'email' connection is, but if there is a way out to the Internet then your LAN will have access to it, and it won't have access to your LAN. Presumably this is what you need?
