What is different between windows 2000 server and windows 2003 server?

Answer 1

Because server 2008 is more updated than server 2003.

Answer 2

Note: Windows Server 2003 was released as an upgrade to Windows 2000 Server. Additional features in Windows Server 2003 include. windows 2003 server support remote desktop feature but in 2000 remote desktop feature was not supported.

Window 2003 server includes IIS server in it. That is the biggest advantage on top of better file system management.

you can change the domain name at any time with help of ntdsutil command, without rebuilding the domain that is not possible in 2000.

1: Windows 2000 server give only 90 days trial version of Terminal server. but windows server 2003 give 120 days trial version.

2: Windows server 2003 shared folder at a time only 65767 user access.

1) In Win 2000 server we can apply 620 group policies but in 2003 we can apply nearly 720 so Win2003 server is more secure than win 2000 server.

2) In 2000 we cannot rename domain whereas in 2003 we can rename Domain.

3) In 2000 it supports of 8 processors and 64 GB RAM (In 2000 Advance Server) whereas in 2003 supports up to 64 processors and max of 512GB RAM.

4) 2000 Supports IIS 5.0 and 2003 Supports IIS6.0

5) 2000 doesn't support Dot net whereas 2003 Supports Microsoft .NET 2.0

6) 2000 has Server and Advance Server editions whereas 2003 has Standard, Enterprise, Datacenter and Web server Editions.

7) 2000 doesn't have any 64 bit server operating system whereas 2003 has 64 bit server operating systems (Windows Server 2003 X64 Std and Enterprise Edition)

8) 2000 has basic concept of DFS (Distributed File systems) with defined roots whereas 2003 has Enhanced DFS support with multiple roots.

9) In 2000 there is complexality in administering Complex networks whereas 2003 is easy administration in all & Complex networks.

10) In 2000 we can create 1 million users and in 2003 we can create 1 billion users.

11) In 2000,there is no shadow copy whereas 2003 shado copy is there.

12)In 2000,we can't rename domain name whereas we can change it.

In 2003 we have concept of Volume shadow copy service which is used to create hard disk snap shot which is used in Disaster recovery and 2000 doesn't have this service.

Answer 4

These are the primary differences between Windows 2000 and Windows 2003 server: 1) Win 2K has Emergency Repair Disk) for disaster recovery scenarios where in Win2K3 we have advanced ASR (Automated System Recovery) 2) In Win 2K only domain wide trust relationships can be maintained. However in win2K3 forest-wide trust is a new feature in active directory. 3) Win 2K uses IIS 5.0 version whereas Win 2k3 has IIS 6.0. 4) Win 2K3 has a new feature called volume shadow copy component. This feature allows taking snapshot backups. 5) Window 2003 server includes IIS server in it. That is the biggest advantage on top of better file system management. 6) You can change the domain name at any time with help of ntdsutil command, without rebuilding the domain that is not possible in 2000. 7) In 2000 support maximum 10 users access shared folder at a time through network but in 2003 no any limit. -Nitin mojor deffent between 2000 server and 2003 Some other new feature: 1 windows server 2003 support masimum access shared folder 65767 at a time. 2. Windows server 2000 Terminal server provide 90 days trial. but win 2003 server provide 120 days.

Answer 6

The main difference is that Windows Server 2007 does not exist :-)

Seriously, I guess you mean 2008: in that case, here you go a Microsoft paper about this subject -> http://www.microsoft.com/downloads/details.aspx?FamilyID=173e6e9b-4d3e-4fd4-a2cf-73684fa46b60&DisplayLang=en

Answer 7

between 2003 and 2008

1)2008 is combination of vista and windows 2003r2. Some new services are introduced in it

1. RODC one new domain controller introduced in it

[Read-only Domain controllers.]

2. WDS (windows deployment services) instead of RIS in 2003 server

3. shadow copy for each and every folders

4.boot sequence is changed

5.installation is 32 bit where as 2003 it is 16 as well as 32 bit, that's why installation of 2008 is faster

6.services are known as role in it

7. Group policy editor is a separate option in ads

2) The main difference between 2003 and 2008 is Virtualization, management.

2008 has more inbuilt components and updated third party drivers Microsoft introduces new feature with 2k8 that is Hyper-V Windows Server 2008 introduces Hyper-V (V for Virtualization) but only on 64bit versions. More and more companies are seeing this as a way of reducing hardware costs by running several 'virtual' servers on one physical machine. If you like this exciting technology, make sure that you buy an edition of Windows Server 2008 that includes Hyper-V, then launch the Server Manger, add Roles.

3) In Windows Server 2008, Microsoft is introducing new features and technologies, some of which were not available in Windows Server 2003 with Service Pack 1 (SP1), that will help to reduce the power consumption of server and client operating systems, minimize environmental byproducts, and increase server efficiency.

Microsoft Windows Server 2008 has been designed with energy efficiency in mind, to provide customers with ready and convenient access to a number of new power-saving features. It includes updated support for Advanced Configuration and Power Interface (ACPI) processor power management (PPM) features, including support for processor performance states (P-states) and processor idle sleep states on multiprocessor systems. These features simplify power management in Windows Server 2008 (WS08) and can be managed easily across servers and clients using Group Policies.

Many features are updated - as security, IIS and RODC.

In security it enable outbound firewall as well as inbound, IIS 7 release, Read only Domain controllers.

1. Virtualization

2. Server Core provides the minimum installation required to carry out a specific server role, such as for a DHCP, DNS or print server.

3. Boot sequence is changed

4. Role-based installation or, services are known as role in it

5. Read Only Domain Controllers (RODC)

6. WDS (windows deployment services) instead of RIS in 2003 server

7. Network Access Protection Microsoft's system for ensuring that clients connecting to Server 2008 are patched, running a firewall and in compliance with corporate security policies.

8. Power Shell Microsoft's new(ish) command line shell and scripting language has proved popular with some server administrators.

9. IIS

10. Bitlocker System drive encryption can be a sensible security measure for servers located in remote branch offices.

The main difference between 2003 and 2008 is Virtualization, management.

2008 has more inbuilt components and updated third party drivers.

Microsoft introduces new feature with 2k8 that is Hyper-V

Windows Server 2008 introduces Hyper-V (V for Virtualization) but only on 64bit versions. More and more companies are seeing this as a way of reducing hardware costs by running several 'virtual' servers on one physical machine. If you like this exciting technology, make sure that you buy an edition of Windows Server 2008 that includes Hyper-V, then launch the Server Manger, add Roles.

Windows Server 2008, formerly codenamed Longhorn, is no leas than 45 times faster than its predecessor, Windows Server 2003, in terms of network transfer speeds. Now whatever the perspective is on Microsoft's last 32-bit server operating system, the fact of the matter is that faster transfer speeds for of up to 45 times is quite an evolution compared to Windows Server 2003. Back in June 2007, Microsoft commissioned a study to the Tally Group focused on the networking performances of its latest Windows client and server operating system, which ended up as the "Enhanced Network Performance with Microsoft Windows Vista and Windows Server 2008" whitepaper. The paper pointed to the fact that both Vista and Windows Server 2008 managed to offer "Dramatic network performance benefits".

Windows server 2008 has been more updated than windows server 2003.
