    1.) My clients have two offices in different locations (A,B) A is the Main office B the branch (Both offices are several miles apart).The main requests are 1) Exchange server to be set in location (A) and can be access in (B) so user can use the same email domain and share calendar by Outlook.
    2) To have a sharing drive that all the user in locations (A) and (B) can view and edit it.
    Both locations have internet access.

    What are the required devices to establish network? Provide brief explanation with data flow diagrams.
    What is the easiest way to do this, do you need advanced routers (Cisco) & Switch or I can keep the normal DSL?
    Do you need two server in both A & B?
    Is there a way to make VPN between the two of them? If not what are the other options might we have?
    What kind of problems may we encounter while establishing this network? Please list them.

    Good Morning. First you have to keep your goals in mind. The two goals lists is to have an Exchange server at location A that can also be accessed by location B for email and calendar sharing and to be able to share a drive that both users can access.

    With these 2 goals in mind you must determine your connect type as this will dictate the hardware that you will need. There are some unknowns based on your explanation, so we should error on the side of security and look at it from the most secure method. Whenever you have 2 locations that you are trying to connect you must determine what type of connection you will have. Since the distance is several miles that would rule out a CAT5 cable between locations. You could go point-to-point wireless, but you would have to purchase antennas, mounting equipment, routers, and there cannot be any obstructions between the two locations. A VPN could be setup that would tunnel over the internet. This would require routers on both ends, a paid internet provider for both locations, the routers would have to have VPN capabilities or you would need to configure a VPN server with the proper protocols.

    The easiest and most secure way of doing this is to pay for a telecom connection between the 2 branches. You could use a T-1, ISDN, MPLS or any other physical connection including a fiber connection. Either way you would need to have a central piece of hardware for PC connections and a hardware or software method of routing the traffic. A physical router is not always needed if a technician can setup Routing and Remote Access on a multihomed (multiple network cards) server.

    The question if you need a server at each location can be answered by looking at your goals. For ease of use, the Exchange server can double as a mail server and a file server, but you could also opt to put servers in each location for local sharing at the branch level. The decision for server placement would depend on the needs at each branch for local resources, such as printers.

    With any network problems can happen. Connection medium could go down, servers could go offline, and viruses could infect the network. Business continuity plans and network disaster recovery plans should also be considered. See the attached diagram for a simplistic view of data flow.
