Active Directory directory service
Active Directory is the directory service for Windows Server 2003 Standard Edition. It stores information about objects on the network and makes this information easy for administrators and users to find and use. Active Directory uses a structured data store as the basis for a logical, hierarchical organization of directory information.
Internet Connection Firewall
Internet Connection Firewall (ICF) provides Internet security in the form of a firewall. Designed for use in the home and small business, ICF provides protection on computers directly connected to the Internet. This feature is available for LAN or dial-up networks, virtual private networks (VPNs), and Point-to-Point Protocol over Ethernet (PPPoE) connections. It also prevents scanning of ports and resources (such as file and printer shares) from external sources.
Remote Desktop for Administration
With Remote Desktop for Administration, you can administer a computer from virtually any computer on your network. Based on Terminal Services technology, Remote Desktop for Administration is specifically designed for server management.
Network load balancing
Previously known as Windows NT Load Balancing Service (WLBS), Network Load Balancing distributes incoming TCP/IP traffic among multiple servers. Your clustered applications, especially Web server applications, can handle more traffic, provide higher availability, and provide faster response times.
Network Bridge provides an easy way for you to connect different LAN segments, allowing users to bridge connections between different computers and devices on their network, even when they connect to the network through different methods.
Internet Connection Sharing
By using the Internet Connection Sharing (ICS) feature of Network Connections, you can connect your home network or small office network to the Internet. For example, you might have a home network that connects to the Internet through a dial-up connection. By enabling ICS on the computer that uses the dial-up connection, you can provide network address translation (NAT), addressing, and name resolution services for all the computers on your network.
Removable Storage makes it easy to track your removable storage media and to manage the hardware libraries that contain them. Because removable optical discs and tapes are less expensive per megabyte than hard disks, Removable Storage and Remote Storage can decrease your costs.
