Hi,
I have two different internet connections with two different ISPs, there are two routers with DHCP relay to the server configured.
I have a wireless adapter and a NIC on my server.
The server controls DHCP & DNS for the network

I want to configure 2 clients to use the 1st internet connection and I want to configure two clients to use the 2nd connection.
How do I do this?
I thought it a simple case of pointing the gateway of one NIC to the 1st router and the other NIC to the 2nd router. However, this doesnt work. I get an error stating the following when I close the TCP/IP properties:
"Warning - Multiple default gateways are intended to provide redundancy to a single network (such as an intranet or the Internet). They will not function properly when the gateways are on two separate, disjoint networks (such as one on your intranet and one on the internet). Do you want to save this configuration?"

My wireless adapter wont enable.
NIC is fine.

Any help greatly appreciated. This is doing my head in. :)
Thanks
Psya

You really can't do it, at least not that way. Only one NIC can have a default gateway. Also SBS has special configurations that require you to use the wizards if you expect all features within SBS to work. The wizard will force you to use one as an internal NIC and the other external NIC.

Two alternatives.
-You can purchase a Dual WAN port router such as the Linksys RV042 which will automatically split the load over the two ISP connections (they should have similar bandwidth).
-You can set up the SBS with 1 NIC. Set the 1st router as the default gateway in DHCP (on the SBS) but on the 2 PC's you want to use the second router, manually configure their default gateway
