I have setup a small office with only one server.  I have never setup a network this way before but it is a request by the owner.  We recently had problems with a previous server shutting down unexpectedly and corrupting the hard drives on the RAID.  The previous server was setup as a usual DNS/DHCP.  The problem with this was when the server was down there was no way for the workstations to receive the internet.  Now we want to supply the switch with the internet through a linksys router that will act as the firewall.  This way they will always have internet even if the new server is ever down and always be connected to eachother.  The problem I am having is with the setup of exchange.  It comes up with the error:

Setup cannot verify that the 'Host' (A) record for this computer exists within the DNS database on server XX.XX.X.XX.

Domain DNS without DHCP behind Linksys Router

The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.

Windows Server 2008 and Windows Server 2008 R2, based on the Microsoft Vista codebase, is the last 32-bit server operating system released by Microsoft. It has a number of versions, including including Foundation, Standard, Enterprise, Datacenter, Web, HPC Server, Itanium and Storage; new features included server core installation and Hyper-V.

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.
