My friend's small office uses a network setup of a 48-port switch (Netgear GS748T), a VPN firewall (Netgear fvs336g), a Comcast modem and a Windows Server 2003 machine. We want to take down the SBS2003 server from the network, because it's an old machine using a lot of electricity and nowadays it's only used for sharing the internet access.
This friend was told by a local IT guy who was in the office for a while that the only thing that needs to be done in order to remove the server is to just physically turn it off and disconnect it and the internet access traffic should be re-routed. I unjoined a test PC connected to the network/server from the local domain (just to be sure) and then turned the server off. However, it's not so simple - after doing this, the internet access is down on all connected workstations. It's still routing to the server.
I'd really appreciate some general tips on why would that happen. I only had a few minutes today to take a look at the network and to check what's going on. As far as I remember, the internet access (modem/DSL) connects to the firewall, and then the firwall connects to NIC1 card of the server, then it goes out from NIC2 card to the switch and then it goes to the clients from the switch. Is that setup even possible? If so, then if I wired the firewall straight to the switch, will we be able to not use the server anymore?
I think this is our current setup:
DSL Modem -> Firewall -> first network card of server -> goes out to the second network card -> switch -> clients
