Network Policy Server
Network Policy and Access Services (NPAS) is a component of Windows Server 2008. It replaces the Internet Authentication Service (IAS) from Windows Server 2003. NPAS helps you safeguard the health and security of a network. The NPAS server role includes Network Policy Server (NPS), Health Registration Authority (HRA), and Host Credential Authorization Protocol (HCAP). In Windows Server 2003, IAS is the Microsoft implementation of a Remote Authentication Dial-In User Service (RADIUS) server. In Windows Server operating systems later than Windows Server 2003, IAS is renamed to NPS. Overview NPS is a role service in Windows Server 2008 which can function as: * RADIUS server * RADIUS proxy * Network Access Protection policy server Features NPSEE enables the use of a heterogeneous set of wireless, switch, remote access, or VPN equipment. One can use NPS with the Routing and Remote Access service, which is available in Microsoft Windows 2000, Windows Server 2003, Standard Edition; W ...

Windows Server 2008
Windows Server 2008 is the fourth release of the Windows Server operating system produced by Microsoft as part of the Windows NT family of the operating systems. It was released to manufacturing on February 4, 2008, and generally to retail on February 27, 2008. Derived from Windows Vista, Windows Server 2008 is the successor of Windows Server 2003 R2 and the predecessor to Windows Server 2008 R2.

Extended support for Windows Server 2008 ended on January 14, 2020. Extended Security Updates (ESU) updates last until January 10, 2023 (January 9, 2024 for Azure customers). Windows Server 2008 is the final version which supports IA-32-based processors (also known as 32-bit processors). Its successor, Windows Server 2008 R2, requires a 64-bit processor in any supported architecture (x86-64 for x86 and Itanium). History Microsoft had releas ...

Internet Authentication Service
Internet Authentication Service (IAS) is a component of Windows Server operating systems that provides centralized user authentication, authorization and accounting. Overview While Routing and Remote Access Service (RRAS) security is sufficient for small networks, larger companies often need a dedicated infrastructure for authentication. RADIUS is a standard for dedicated authentication servers. Windows 2000 Server and Windows Server 2003 include the Internet Authentication Service (IAS), an implementation of RADIUS server. IAS supports authentication for Windows-based clients, as well as for third-party clients that adhere to the RADIUS standard. IAS stores its authentication information in Active Directory, and can be managed with Remote Access Policies. IAS first showed up for Windows NT 4.0 in the Windows NT 4.0 Option Pack and in ''Microsoft Commercial Internet System (MCIS)'' 2.0 and 2.5. While IAS requires the use of an additional server component, it provides a number ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Windows Server 2003
Windows Server 2003 is the sixth version of Windows Server operating system produced by Microsoft. It is part of the Windows NT family of operating systems and was released to manufacturing on March 28, 2003 and generally available on April 24, 2003. Windows Server 2003 is the successor to the Server editions of Windows 2000 and the predecessor to Windows Server 2008. An updated version, Windows Server 2003 R2, was released to manufacturing on December 6, 2005. Windows Server 2003 is based on the consumer operating system, Windows XP. Windows Server 2003's kernel has also been used in Windows XP 64-bit Edition and Windows XP Professional x64 Edition, and was the starting point for the development of Windows Vista. Overview Windows Server 2003 is the follow-up to Windows 2000 Server, incorporating compatibility and other features from Windows XP. Unlike Windows 2000, Windows Server 2003's default installation has none of the server components enabled, to reduce the attack surface ...

RADIUS
In classical geometry, a radius ( : radii) of a circle or sphere is any of the line segments from its center to its perimeter, and in more modern usage, it is also their length. The name comes from the latin ''radius'', meaning ray but also the spoke of a chariot wheel. as a function of axial position ../nowiki>" Spherical coordinates In a spherical coordinate system, the radius describes the distance of a point from a fixed origin. Its position if further defined by the polar angle measured between the radial direction and a fixed zenith direction, and the azimuth angle, the angle between the orthogonal projection of the radial direction on a reference plane that passes through the origin and is orthogonal to the zenith, and a fixed reference direction in that plane. See also *Bend radius *Filling radius in Riemannian geometry *Radius of convergence * Radius of convexity *Radius of curvature *Radius of gyration ''Radius of gyration'' or gyradius of a body about the axis of r ...

Network Access Protection
Network Access Protection (NAP) is a Microsoft technology for controlling network access of a computer, based on its health. With NAP, system administrators of an organization can define policies for system health requirements. Examples of system health requirements are whether the computer has the most recent operating system updates installed, whether the computer has the latest version of the anti-virus software signature, or whether the computer has a host-based firewall installed and enabled. Computers with a NAP client will have their health status evaluated upon establishing a network connection. NAP can restrict or deny network access to the computers that are not in compliance with the defined health requirements. NAP was deprecated in Windows Server 2012 R2 and removed from Windows Server 2016. Overview Network Access Protection Client Agent makes it possible for clients that support NAP to evaluate software updates for their statement of health. NAP clients are compute ...

Active Directory
Active Directory (AD) is a directory service developed by Microsoft for Windows domain networks. It is included in most Windows Server operating systems as a set of processes and services. Initially, Active Directory was used only for centralized domain management. However, Active Directory eventually became an umbrella title for a broad range of directory-based identity-related services. A server running the Active Directory Domain Service (AD DS) role is called a domain controller. It authenticates and authorizes all users and computers in a Windows domain type network, assigning and enforcing security policies for all computers, and installing or updating software. For example, when a user logs into a computer that is part of a Windows domain, Active Directory checks the submitted username and password and determines whether the user is a system administrator or normal user. Also, it allows management and storage of information, provides authentication and authorization mec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
