windows 2003 server internet connection

I recently installed windows 2003 server.after the installation, I configure
the server for active directory, DNS server and DHCP server using a wizard.It
is connected thru a switch and another computer.So basically I have have a
server and a client on my network.The active directory works fine as I tested
it.My question is how will I able to connect the server through the
internet.?The current network setup of the company is that it has a simple
LAN and all computers are using dynamic configuration for the IP.There is
only on router/wireless router in the network that acts as DHCP, and DNS
server.



these are some of my thought regarding the scenario...

1.Im planning to buy another LAN Card, so basically I'll have 1 Lan card
connected to the internet and another one for my local area network.then all
computers will be configure to use proxy server, which is the server.but what
will happend to the wireless connection?



2.is there a way for me to use the current LAN network? as I see it, the
sever has used diferent DHCP scope with the current DHCP scope of the
router.should I make the server used static IP within the scope of the router?



Please give me your thought on this one...thanks

It is not recommended to run DC on a multihomed computer. You can add a
router for internet access. This search result may help.

No, you cannot use DHCP on the router for your domain machines. Active
Directory is not compatible with the DNS or DHCP settings used by the a NAT
device (which is probably what your Internet "router" is). Your AD machines
must use the local DNS. If you connect your LAN to the company LAN, there
will be two active DHCP servers on the network which will cause chaos.

Do not even think about putting an extra NIC in the DC. This is not a
solution. You do need a router between your AD network and the company
network, but do not use the DC for this.

Without separating the networks with a routwer, you could run your
domain using static IP addresses in the same subnet as the company LAN. You
would need to disable DHCP on your DC before you put the AD machines in the
same network as the other company machines.

You would manually configure the AD machines to use the router IP as the
default gateway but use the DC for DNS. You would modify the local DNS to
forward to a public DNS service (such as your ISP) to enable lookup of
external URLs.
