What Are The Advantages And Disadvantages Of An Intranet Network?

No disadvantages really...it adds a hop to the internet, but it adds a bit of security to your home or office pc's by putting up one more road block for crackers. Intranet allows for local sharing of files, printers and such with less worry about someone else utilizing or damaging your equipment.

One disadvantage though. Most people who set up an intranet at home for sharing, tend to leave themselves wide open for a replicating virus. For example, at home, you have a shared drive. Every one in your house accesses the drive so you set it up with no passwords ie they open it like they would a drive on their on PC. One of the kids downloads a virus. It can infect the shared drive and then any pc connected to this shared resource is also at risk.

Each machine needs a good solid antivirus anyway (not norton or mcafee) and to be kept up to date. But sometimes, they just don't catch them.

Hope this helps
