We have two ADSL connections into our business and I am wanting to configure them so that in the event of one service failing then the other will connect. <br />

I am also wanting to make certain server traffic go through one ADSL connection and the rest go thru the other. <br />
<br />
I have a windows network, is it a matter of configuring the DHCP server to use both routers or is there something more complex I need to do. <br />

I am aware there are routers available with dual wan ports but if I can avoid that expense then I would be happy.

Combine ADSL lines.

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.

Routers

The Windows operating systems have distinct methodologies for designing and implementing networks, and have specific systems to accomplish various networking processes, such as Exchange for email, Sharepoint for shared files and programs, and IIS for delivery of web pages. Microsoft also produces server technologies for networked database use, security and virtualization.
