In 2k3 there is stub zone but in 2k it is not there.
cross trust & shortcut trust are available only in
2k3.group replication problem was there in 2k but it is
removed from 2k3.
In 2k you have to create trust between parent & child but
in 2k3 the trust between parent & child is automatically

created when you create parent & it's child.
you can't change the domain name in 2k but in 2k3 we can

Answer / sunny

"Windows 2000" is also called as "Win2k" . It is an
interruptible, business oriented and graphical operating
system which was just designed to work along with
the "uniprocessor" or "symmetric multi processor 32 bit
Intel x86 computers". It is a part of the "Microsoft
Windows NT" series of operating systems. It was succeeded
by "windows XP" in "windows server 2003". The "Windows 2000
Server" has extra and additional functionality which
includes the ability to provide the "Active Directory
services". Active directory services is a hierarchical
framework of resources. Windows 2000 server also proved
Distributed File System (it is a file system which supports
file sharing) and storage volumes for fault
redundancy. "Windows Server 2000" supports upto four
processors, up to four GB of RAM. "Windows 2000 server" is
designed to use for web applications, file servers, print
servers etc.
Windows 2003 server is a "server operating system". It is
created by Microsoft. It is also called as successor
of "Windows 2003 server". It's performance is much better
than the "Win2k". it can be used as "centralized management
tool" for the printers and files. It gives "enhanced quota
management". "Windows 2003 server" also
includes "compatibility modes" to allow the older
applications to run and execute with larger stability.
You can have a look at
http://wiki.answers.com/Q/What_is_difference_between_windows
_2000_server_and_windows_2003_server
However,in order to optimize its function, I think you
should partition your disks
sometimes.http://www.softpedia.com/reviews/windows/EASEUS-
