Design a Communications Solution [Microsoft Small Business Specialist Primer book excerpt]

G’day folks – I am the publisher of the above title and I like to hold a daily book virtual book reading by posting up a passage. Enjoy!

Design a Connectivity Specification

for Networking and Remote


One of the reasons this particular client had a dial-up connection when I first started working with him was really to save a penny. It took me a while to convince him that he would be able to use high-speed Internet access and still come out better on the cost/benefit equation.


SBS 2003 is easily implemented on a broadband connection, using either a dynamic or a static IP address. I always recommend using the static IP, especially if you are running the Exchange server as your primary e-mail solution and want to make good use of the Remote Web Workplace. While configuring the E-mail and Internet Connection Wizard (CEICW) “for a direct broadband connection,” you will be given the choice of either using a dynamically assigned IP address or entering a static IP as your broadband connection option. This will be performed for the network adapter on the server that will oversee the external connection. Note that once a small business person uses a high-speed broadband connection, it is unlikely she will return to a modem connection (or anything slower). This is a design consideration: Speed is addicting!

There are two traditional methods of broadband connectivity: DSL and cable. DSL is preferred by many small businesses, as it’s a service typically provided by the telephone company and oriented toward business use. DSL is usually offered with a static IP address (but you’ll see the exception to this in a moment). Cable is more consumer-oriented and typically uses a dynamic IP address, but in some cases can be much faster than DSL. So, there are truly two choices here. Back at the customer site, we ended up purchasing a DSL line, because we were only 300 feet from the CO (central office). DSL can be easily set up with the CEICW since it includes the option to set up “a connection that requires a user name and password” (PPPoE—Point-to-Point Protocol over Ethernet). This is the “exception” referred to earlier. Thereby we were obtaining a dynamically assigned IP address. This scenario required two network adapters— one for the

local network and one for the Internet, and the server would provide routing and network address translation (NAT) services. But I’m starting to jump the gun on a few technologies that will be detailed later in this book. However, the design phase must necessarily incorporate some technical considerations at this early stage.

Local Router with Static IP

At another customer site, we ordered a static IP address and therefore used the static setup option in the CEICW titled “a local router device with an IP address.” This is the SBS way for connecting a static IP DSL router, dial-on­demand router, or ISDN router. The static IP address is supplied by the ISP on the external network adapter card or interface. If the connection requires authentication information, you must configure the router with a user name and password, even if your router supports Universal Plug and Play (UPnP). UPnP is a standard that allows SBS 2003 to easily configure the router device.
