Windows 2008 Server has  increased security, reliability, and performance. Windows Server 2008 R2 extends connectivity and control to local and remote resources. This means your organizations can benefit from reduced costs and increased efficiencies gained through enhanced management and control over resources across the enterprise.

Windows Server 2008 is built from the same code base as Windows Vista; therefore, it shares much of the same architecture and functionality. Since the code base is common, it automatically comes with most of the technical, security, management and administrative features new to Windows Vista such as; improved image-based installation, deployment and recovery; improved diagnostics, monitoring, event logging and reporting tools; new security features such as BitLocker and ASLR; improved Windows Firewall with secure default configuration.

It offers an updated Web server role, Internet Information Services (IIS) 7.5, and greater support for .NET on Server Core. Design goals for IIS 7.5 concentrated on improvements that enable Web administrators to more easily deploy and manage Web applications, that increase both reliability and scalability.
