Hi:

I am really new in this kind of topics, and my question is:

Which is better: 2 network adapters or 1 adapter in server

I made a searching and I can't find anything until now.

 

The fact is that I found a server in this store that has 2 network cards in it (SBS 2003). One card connects the ethernet cable that comes from the modem/router and the from the other adapter goes the ethernet cable which goes to a hub.

 

I heard that the previous administrator left like that because at some point the Internet connection used to get loss. Then, he decided to design a 2 adapters network.

The clients (5) use windows XP and some (3) Vista.

 

I try to see if: wouid it be easier to re-build a one card only server?

 

Any advices?

Hi Edi,

 

I don't know what you mean with re-building a one card only server, as it isn't needed to rebuild a server for a change in the network setup. If you have 2 nics, you will benefit of the basic RRAS/firewall. You can also use ISA (if you have SBS Premium) for a proper firewall and proper logging.

With only 1 nic  in the server, you don't have basic firewall and are depending totally on the router for firewall capabilities. Cheap routers are not proper firewalls and hardly have any logging at all.
