Hi,
I think you have got a lot of valuable information. I just want to add some supplemental information to you.
Actually, 3 NICs on SBS 2k3 system scenario is not a recommended configuration. The most valuable feature in SBS
2k3 is all kinks of Wizard that help you to configure your SBS simply. The complicated configuration can be achieved
easily by these pre-defined Wizards. It can largely lower your maintenance labor and cost. It is one of the main
purposes that Microsoft design Small Business Server 2003. If three NICs are installed, you will lose most of these
great features.
In addition, the 3 NICs with 2 network segments on your SBS server will cause lots of side issues. The ISA server
needs to be configured manually. You will have lots of work to do and the maintenance will be complicate and time-
consuming.
If you really want to have more than one LAN in your SBS network, it is recommended to use additional routers such
as hardware router or Windows 2000/2003 routers. The following articles are for your reference.

Thanks for your time and have a good day!

| I have a SBS 2003 Server with 3 Nics, running ISA 2000.
| 1 Nic for the LAN 10.0.10.120
| 1 Nic is for the Internet Connection 10.0.100.120
| Everythings was working fine
| Now I am enabling the third Nic for a second LAN segment
| that comes from a router. IP is 10.0.100.121.
| In the switch where 10.0.100.121 is there are 3 Server
| including this one, and a PC. I can ping everything but
| this server; I cann't access this server thru 10.0.100.121
| What am I doing wrong, is the IP configuration the
| problem? Or is ISA preventing this to happen?

| In Networking Advanced, Server Local Area Connection is
| first, then Network Connection2, then Network Connection.
