How to create network between 5 local locations

Application Server
Email Server
Network design

5 tire sales locations want to their locations to a common application server and possibly an email server.


My brother does business with the company and the owner said that he was quoted $70K to do the job. At the moment, they only have their onsite PC's.

I believe that there has to be a much cheaper solution that addresses their needs. I am far from an expert but believe their is a solution I can handle.

About me:

I am great with building and supporting PC's and at one time had a CCNA but have have no MS certs. I work in a data center where I build, install servers and troubleshoot connectivity issues.

Assuming that each site as a DSL line or cable modem…

Get each site a LinkSys RV042. These are nice little routers which would replace the existing routers at each site.

These routers are nice because they support site to site VPN connections.

Each office is its own TCP subnet, and the routers are configures to all VPN to each other so that any traffic that needs to go from one site to another can. For example…

Site 1:
Site 2:
Site 3:
Site 4:
Site 5:

These routers cost a couple of hundred dollars each.

The servers are going to be where a lot of cost comes in. I assume you’ll want to use Active Directory for authentication so that any employee from any shop can log into a computer at any shop. You’ll want two computers to serve as domain controllers. You can do it with one, but if that server fails you’ll have a lot of problems. Then you’ll need something to run your mail server. Assuming that you want to use Microsoft Exchange that’s where a lot of cost comes into play.

There are less expensive solutions out there, but they can be more complex to setup and maintain where Exchange is pretty easy for a small company.

Without looking at server and licensing prices I would say that $70K is VERY high. Honestly somewhere in the $20k range is probably more reasonable. If I were to price out the job as a consultant I could of course give a more accurate number.

    I think, you must tell us the distance about one location to another, about IP address I think you have learn in your CCNA, :)
