I have a windows 2003 server with two NIC's. The intent is to provide public web access thru one NIC and provide private office services thru the other. I cannot have the public access see anything but the web services via IIS. The private network cannot access or be accesses by the public network. My efforts so far have failed and I need a bit of direction. Any references or direction will be greatly appreciated.

Hello, enable RRAS so that the server will act as a router.

Enabling RRAS will allow for the routing of packets between network interfaces. If your intent is to not allow each segment to access the other, you should not enable RRAS. By default, just having a multi-homed computer will not provide the access you are indicating is present, unless you configured it to do so. Can you elaborate more on how the network design that is passing through the system allowing public to access the private site and the private to access the public side?
