If you have two seperate buildings, about 100 meters apart. I wanted to connect the computers of both buildings together..to be able to link (share) company files (databases) .
What should we do?? I have heard about leased line!! even.IP-VPN.... even wireless antenna... :(

What is the best/cheapest/safest way to link the computers together??
Can anybody help??

Not sure if wireless networking will do-- it may not be safe though. Any Tom, Dick and Harry could get on the internet through you.

dis depends on ur company's budget...i'm still a student majoring in networking so im not really an expert yet but based from what i have learned so far...d best reliable way is to create a local area network (lan)...if each building already have a network then u can connect d two using a virtual private network (vpn)...each building will be in a vpn and the 2 vpn will be connected using a router or a switch with routing capabilities (if u have a low budget)...d leased line u've heard probably refers to an internet connection...most companies have a leased line to an internet service provider (isp)..its a dedicated line given by d isp to d company so they can connect to the internet...

wireless networking still has a lot of limitations in particular in terms of distance, security and environment...

so bee ur also from d philippines..i'm from d phils too!

as it's been said, depends on the company's budget and what they want to do, what are the security requirements, number of users, speed, etc.

Wireless is NOT a good idea.

A leased line is not necessary unless you need to setup a WAN (wide area network), which is not the case if the distance is 100 meters.

Basically you will need at least one server, a hub or switch, network cable. You have to make sure all computers have nic (network interface card) and you have to decide what type of OS you will run on the server, protection, administration, etc.

In a word, it's not a question you can get answered here and depending on the needs, it can end up costing from a few thousands to millions.

You should consult a network administrator or a system analyst to first decide what the company needs/wants to do.

sorry i was mistaken..its virtual local area network (vlan) not vpn...d vlan would make ur network look as though its in a two separate lan but in truth d two building is only in one lan...

I don't think you can recommend the network topology without knowing the needs and budget, and what resources they already have.

a virtual local area network seems unnecessary unless they need to descentralize resources and access through a common IP, that's if they are using IP networking.

as I said, there are many options, from a virtually zero cost peer to peer network to extremey complex and expensive options.

A vlan can be complex from the software point of view, a VPN is gonna be very expensive and unnecessary unless they want to access the network over the internet.

Hi there.. :) Thx.
They were planning to convert one building as the sales office while the other building will house the accounting dept. Each building has a network of computers already.. with a server and 3 to 4 workstation (each building)... Our new system programmer installed a new "program" for the company with OS-win2000.. and the problem is we want these two buildings to be "linked" together... Well..our programmer has no idea how.. because they said they haven't done anything like this before..
About VPN... what kind of company should I call?? An internet provider or telecoms company ...or a computer hardware company?? (May idea ka ba kung magkano yun?? ) :D :D

it can get really complex to configure a network. You need a network administrator, not a programmer.

If the servers are running Windows 2000, you can configure them to work in tandem, basically you can log on to one server and be allowed access to all network resources, but you also will need to set permissions (who can see this resource and who can't). You will have to configure the workstations to logon to one of the servers, probably mapping some server drives, assign printers, etc. The best way is to create a domain, but for that you need a specialized server called domain controller.

About VPN, there are several providers, Ravlin, Cisco. I don't see the need for that unless they want to access network resources over the internet (for example from home). You need a VPN server, that will run the server software, and need clients on the machines that are going to connect through the internet, you need to buy licenses for each user (it's pretty expensive). And you need to setup a firewall, the best idea it's an appliance (easy to configure) but firewalls can be pretty expensive as well. VPN is a very expensive solution and not easy to configure, there are many other aspects and I don't know all the details.

Microsoft has a product that is called small business server, it's basically a Windows server 2003 with limited users licenses and with preinstalled software (SQL server, exchange), that can be a good solution, but don't do this on your own, hire a network adminstrator otherwise you will get in a big mess.

bee as already said u need network administrators to do this stuff...isp providers can only give u internet solutions...i suggest u ask companies that handles networking problems...d gastos is more on d hardware stuff...with d switches and cables...and since magkahiwalay ung buildings d placing of cables may also be a problem..but as u said there's only 3 to 4 workstations in each building d nmn ganun kalaki ung network so that may help if ur working on a tight budget...its too bad christmas break ngaun so i can't ask my professors...if ur not in a hurry...u can give me more details and i can ask my professors wen school comes back on january...don't worry d consultation fee is free ;)
