What are the
differences between Windows 2000 Server and the newer
version Windows Server 2003?
From a "web hosting view" two major changes
have been made to Windows Server 2003. The first is
an update of Microsoft's web server, the Internet Information
Server (IIS). It was updated from version 5.0 to version
6.0. The new IIS 6.0 was re-designed from the ground
up and offers compared to the older version great improvements
in performance, security, and stability.
The second change is the inclusion of the .Net Framework.
The .Net Framework is a completely new software development
platform which has the potential to dramatically change
the way applications are developed and hosted.
In addition to that there are literally thousands of
other smaller changes in the new version, all of which
add functionality, improved security, and an increase
of stability and performance to the new operating system
What are the benefits of Windows Server 2003?
The new IIS 6.0 is much faster, more stable, more secure,
and also more scalable than any earlier version. IIS
6.0 has the potential to host several thousands of web
site more than can be hosted on a server with IIS 5.0.
It is important to say that the performance improvements
are much higher if .NET programming is used.
The inclusion of the.Net Framework allows users to take
advantage of all of the benefits of Microsoft's newest
development platforms. It will also allow immediately
begin developing applications which take advantage of
Will all current applications run on Windows
The vast majority of applications that run on Windows
2000 Server will run just fine on Windows Server 2003.
However there are a couple, including one very important
one that will not run on the new version. Among the
Microsoft applications are older editions of the Redmond,
Wash., company's SQL Server database, including versions
6.5 and 7.0.
Microsoft Exchange Server 2000 and older versions are
also affected. There is no choice but to wait for Exchange
Server 2003. Microsoft will be releasing the next version
of Exchange Server later in 2003.
What are the differences between the four Windows
Server 2003 editions?
The Web Edition is targeted for Internet Service Providers
(ISPs) and Web Hosting Companies offering dedicated
server hosting and shared web hosting. Microsoft does
not allow running software like SQL Server or an Internet
mail server on the Web edition. The Web Edition supports
a maximum of two processors and a maximum of two GB
The Standard Edition is the right edition for servers
that wil be used as file or printer sharing servers.
It supports a maximum of four processors and four GB
or RAM and is a full-featured version of Windows Server
Targeted for networking, messaging, inventory, customer
service systems, databases, and e-commerce web sites,
the Enterprise Edition will support up to eight multiprocessors
and up to 32 GB of RAM. A 64-bit version is also available,
but it requires 64-bit processors. This edition offers
eight-node server clustering for clustering SQL Server
or other cluster-aware applications.
Lastly, there is the Datacenter Edition. It is designed
for highest levels of scalability and reliability. It
supports up to 64 multiprocessors and 512 GB of RAM.
This version is only for very specialized, mission-critical
application requirements and is also available in a
