Getting busy on testing out some appl like SCCM 2007 and SCOM made me to stay away from blogging, so thought of writing one.
It’s been quite a time for windows server 2003, people already started using windows server 2008 and are happy with the new features available. This article gives you the new features available in Windows server 2008.
1. Role based installation
Windows server 2008 has quite number of roles in the server manager, which can be installed as when required. The below are the roles,
Active Directory Certificate Services
Active Directory Domain Services
Active Directory Federation Services
Active Directory Lightweight Directory Services
Active Directory Rights Management Services
Network Policy and Access Services
Print and Document Services
Remote Desktop Services
Web Services (IIS)
Windows Deployment Services
Windows Server Update Services (WSUS)
In the above some of them are new features, which I will discuss later. Also some of the above features are specific to certain edition of the windows server 2008. Please check out http://www.microsoft.com/windowsserver2008/en/us/r2-compare-roles.aspx
2. Server core
One of the expected feature and most welcomed feature which going to drive Microsoft server OS forward is the server core feature. Like UNIX server environment, you can have the server core shell windows alone, no need of having GUI with fancy GUI drivers. But the optional GUI option also available. The trend of having the single shell for server operation in a Microsoft was a dream for most of the system administrator. This server core installation option allows us to install specific server role like DHCP or Print server. So all server operation can be done sufficiently in command prompt, no more GUI specific configuration stuffs required unlike previous versions.
3. Virtualization – Hyper V
Virtualization enables you to have multiple logical servers in a single server provided with all functionality like networking, dedicated memory, high performance, etc. Since virtualization as a technology is a revelation in IT because of its cost reduction. Already we have application like VMWARE and virtual PC making ways. Hyper V along with the server OS is definitely good. Just to make it interest, please check out the below link

Powershell was as expected one. Since Powershell started making news from the release of the exchange 2007. The entire administrative task can be done with ease using the Powershell, which makes the system administrator life easier. Powershell has the built-in active directory related cmdlets which can be effectively used for multiple purposes.
5. Right Management Services
Data security has been taken to the next level by means of this service. We don’t have answers for the security on documents which the end users who have the access or the mails which have the sensitive information can be forwarded to anyone outside the organization. This service helps in preventing the above scenarios. Since it is integrated with the active directory helps in providing security for file level and also emails.
6. RODC – Read Only Domain Controllers
It is one of the new features which have excellent features in terms of both functionality and design. It provides solution for the scenario like most of the branch offices DC server lacks the quality administration, henceforth chance are there for poisoning the Home DC by replicating the faulty data’s. This RODC only acts as a Read only DC; it won’t be chance to write any data and resulting in no need of sending any update to the main office. So it is unidirectional update i.e., only from normal DC to RODC. RODC do wonders for multi-site work environment.
7. IIS 7.0
IIS 7.0 has been improved mainly in terms of security when compared to the IIS 6.0. I don’t know much about this application interiors, I leave it to you people to check out the new features from the link http://learn.iis.net/page.aspx/110/changes-between-iis-60-and-iis-7-security/ . These improvements are with respect to Authentication, Authorization, SSL, Web Service Extension Restriction List and IP restrictions.
8. Enhanced Terminal Services – Remote desktop Services
The former terminal service has been renamed to Remote desktop Services and which has been significantly improved. The features are the following.
RemoteApp – Server based remote application programs can be accessed in the local computer using the terminal services, which looks like normal execution of the local application.
Web Access – Using this they will be able to access the remote app programs through internet via browser.
Gateway – Using this feature the user will be able to take the remote connection from the outside LAN i.e., from public provided the TS gateway is configured.
9. Network access protection
Network access protection is the new features which mainly related the security. This policy enables us to have the control over the connection to domain network based upon some threshold compliance, in case of any systems which are sort of the threshold compliance; it will force the missing compliance and then allow the host to connect it to the LAN. For e.g., we have the deployed some security patches for all the users, one of the user who is not part of this activity came after a long vacation. There is a chance for some security lapse; here comes the role of NAP to enforce the missing one.
10. Group Policy Management Improvements.
Group Policy Management has many improvements in account policies, password policies, etc. We have special query option in the GPMC console in order to list out the policies which are set or also no need to search for a particular policy in the hierarchy can be easily searched with the namespace.
11. Windows Deployment Services:
Using this deployment services we can even able to deploy the OS. In previous version, this option was not available and also it can be achieved by application like SCCM. Windows Deployment service use the TFTP protocol and makes it comparatively faster. Moreover it has the option for Autocast or schedulecast deployment.
The above are main new features which come to my mind; Security of the Server OS is definitely improved much when compared to the earlier versions.
Hope the above information is useful.
