subject: Sbs Exchange 2003 Is More Effective Than Peer Network [print this page] Most small business owners rely on peer network. In this system, there are typically no centralized resources and files are shared from a standard XP, Windows 2000 or Windows NT workstation. Each system is typically configured with a PoP3 email account that checks the ISP server on the Internet every 5 minutes and perhaps some virus protection software that also regularly checks the Internet for updates. But this solution is not very scaleable and once an organization starts growing, it needs a better solution. Small Business Server or SBS Exchange 2003 gives small businesses a chance to go to the next level by providing centralized user management and an integrated backup solution.
A centralized virus protection can also be installed on this server, for example, the Trend Micro Client Server Messaging, or Symantec End Point Protection. After this, the server checks for updates every hour and then updates each of the clients accordingly. This saves on performance issues as individual clients no longer use the Internet to check for updates.
But you need to be very careful while configuring SBS Exchange 2003. In most environments, the exchange server will sit behind a firewall, many users and IT consultants fail to forward port 25. Since server to server email communication takes place on port 25 it becomes impossible to send email without this firewall configuration.
Reverse and forward DNS settings should also be done properly. If the public IP address of the exchange server does not have properly configured reverse and forward DNS settings many popular email services will deny emails as spam.
Hence you need an experts guidance to set up the server system so as to make the most efficient use of resources.
