First, install DNS service on the server with those 2 NICs,
If you are already using DNS on your local domain, you should configure this server as secundary DNS server.
If it is the only DNS server, then skip this remark, and set up a local DNS domain (non-registered !)
e.g. mydomain.com
In the domain MMC snap-in, select your server name under the DNS section,
Go to the properties of that servername, and then go to the forwarders tab, enable it, and fill in the IP address of ANY internet DNS server.
If you want to know the DNS servers of your provider, simply do a ipconfig /all, and look what IP addresses your external NIC has got from your ISP's DHCP server.
On your clients, make sure that they are using your local DNS server to resolve names.
(Go to properties of TCP/IP and fill in the local IP address of your new DNS server, set it as primary DNS server)
Also, on your clients, right click on 'my computer', go to network identification, click on 'properties' and then on 'more' and fill in the DNS domain name as DNS suffix (e.g. mydomain.com)
To allow your clients to use your server as internet gateway, you must set up NAT on your server.
Install RRAS, and configure it as NAT server :
Right click on your server name in Routing & Remote Access, choose Configure and enable routing & remote access
Click next
Select 'internet connection server', select 'set up a router with NAT'
Use the selected internet connection : select the external NIC.
Click finish
On your clients, set the server's internal NIC IP address as default gateway.
Now you should be able to pîng internet IP addresses from your clients.
If that works, try to ping to
If that works, you will be able to surf the internet from your clients...
Good luck
