Networking Server Applications



A network server host on a Windows network uses the Windows server 2000 or 2003 Server software disks. The 2003 version has been separated into various specific types of server. An all in one inclusive server is the exchange or enterprise server version. There is also the web version, enterprise version, media version, and others. Here we deal with only two types – the enterprise and web versions.


Server 2000 is the older version from Windows that really has a lot of bugs and is less intuitive than 2003. We won’t go into nor use it here.


Server 2003 – Web Edition


The web version of the server software is a specific function package that only hosts web pages and music sources. It interfaces with an exchange or enterprise server seamlessly. The web server is based on the MMC (Microsoft Monitor Console) design. To enter the console, click on the start button, transverse to programs, to administrative, to IIS services. This will bring up a screen where you can manipulate and control the services you wish to host. You must link the web pages you want to host on this screen.

Create your web pages anywhere you would like but to get them seen on this server, they must be located within the IIS system in the web pages active directory. The pages may crosslink to other servers if required.


Server 2003 Enterprise Edition


The Enterprise Edition of Windows 2003 is more or less the master plan of servers. It can be configured to perform all the tasks that one wishes to have a server do. It is a DHCP, DNS, WINS, IIS, Application, Media Services, file, email, chat, blogs, newsgroups, and just all around good guy server. However, depending on the number of services you wish to provide, a lot of memory, a lot of disk space, and a lot of computing power needs to be available. Redundancy backups are a very good idea in a real environment such as a corporation or ISP or just about any business. The company records may be kept on a file server, necessitating redundancy and backups.

Windows 2003 has an updated user friendly configuration menu that replaced the older manual MMC console in Windows 2000 server. Just click and point will configure your server according to your requirements. As with everything Windows, the server application software can be a little buggy so it is important to work with the package and get to know its inner workings very well.


Email


Incoming mail uses the POP3 protocol – Post Office Protocol v3

Outgoing Mail uses the SMTP – Simple Mail Transfer Protocol

Client email – such as Outlook – puts email software on client rather than server. When one requests to read an email – it actually downloads the file to the home computer and then deletes it from the server.


Directory Services – Directories reside on the server – The process uses Windows Active Directory or Novell Directory Services in the case of IPX. Within this service permissions can be granted depending on security policies.


Centralized vs. distributed applications


Application Server – applications (such as games) are basically shared across the network.





Rest of time spent on configuring the servers.
