NetBIOS, broadcasts names to listening nodes on the network. NetBIOS utilizes a User Datagram Protocol (UDP) query to broadcast names. NetBIOS names identified computers on the network before the introduction of Windows 2000. The NetBIOS name is resolved to an IP address through Windows Internet Name Service (WINS), broadcasting, or the LMHOSTS file. If the …
DFS (Distributed File System) provides a mechanism for administrators to create logical views of folders and files, regardless of where those files are physically located on the network. DFS also allows administrators to distribute shared folders and work loads across several servers for more efficient network and server resources use. Fault tolerance network storage resources …
A NetBIOS name is an identifier that NetBIOS services running on a computer use. It is a combination of a 15 character (byte) name and a 16th character denoting the service. These names identify resources on the NetBIOS network. NetBIOS cannot do name resolution on the Internet because NetBIOS names are single part names and …
While encryption can be a robust security technology, users have to implement a public key infrastructure (PKI) to make it beneficial and trusted within an organization. The Windows 2000 and Windows Server 2003 PKI implementation resides in Certificate Services. A public key infrastructure is the collection of technology, protocols, services, standards, and policies that control …
Automatic Private IP Addressing (APIPA) Overview DHCP is a service that functions at the application layer of the TCP/IP protocol stack. One of the primary tasks of the DHCP service is to automatically assign IP addresses to DHCP clients. A server running the DHCP service is called a DHCP server. The DHCP service automates the …
Virtual Private Networks (VPNs) enable users to connect to a remote private network through the Internet. Virtual private networks therefore span the Internet because the user connects over the Internet to the remote VPN server. With a VPN, data is first encrypted and encapsulated before it is sent to the remote VPN server. When the …
Opening TCP ports in Windows may be necessary for certain applications to run correctly. Each application may require a specific port to operate on. While a computer can and does open ports on its own, it may have to be done manually in certain situations. Here is a simple procedure. Step 1. Launch Windows and …
An Overview on Secure Sockets Layer (SSL) The Secure Sockets Layer (SSL) protocol was developed by Netscape Communications, and enables secure communication over the Internet. SSL works at the transport layer of Transmission Control Protocol/Internet Protocol (TCP/IP), which makes the protocol independent of the application layer protocol functioning on top of it. SSL is an …
IPv6 stands for Internet Protocol version 6. IPv6 is the latest version of the network-layer protocol for packet-switched networks. The version that is generally used is IPv4. One of the reasons for the upgrade to IPv6 is that it allows greater space and flexibility in assigning IP addresses. For instance, IPv4 is based on a …
In Routing and Remote Access Service (RRAS), NAT can be used to provide basic Internet connectivity for small offices or home offices. NAT translates IP addresses and associated TCP/UDP port numbers on the private network to public IP addresses which can be routed on the Internet. Through NAT, host computers are able to share a …
