Windows Server 2008 has a lot of extras that you can add on to enhance the server…..for free. We call them Roles and Features. Roles being major components and Features being enhancements to the roles. Here are a few.
AD RMS (Active Directory Rights Management Service)
AD RMS allows users, as opposed to Network Administrators, the ability to assign permissions to content. In the past, we as Net Admins, had to manage this. Now, with RMS aware applications like Office 2007, users can do this as well. Think about the PDF file that would not allow you to print it. Users can do the same to help protect their shared content. They can even determine who can read and modify their content, regardless of NTFS or file share permissions.
AD FS (Active Directory Federated Services)
AD FS allows you to securely share your networks resources with other organizations. The nice thing about AD FS is that you give access permissions to an organization and the other organization manages the user accounts. This give you the control off the access, the other organization the control of who gets the access, and SSO (Single Sign On) for the users.
Hyper-V allows you to run servers (or clients) in a virtual environment. This allows you to save money in hardware and electricity. It alsow has some unique options to recovery quickly from a down physical server.
NAP (Network Access Protection)
NAP helps to protect your network. Let’s say that some who a users laptop mysterious lost its antivirus software while away from the office for a month. NAP can be set to not allow this client access to your secured network. Instead, it sends it to another network that will allow it to download and install the antivirus product, clean itself, and then admit it into the secure network.
