Q&A Q. What type of firewall is the Windows Firewall? A. The Windows Firewall is a stateful firewall, meaning it keeps track of the state of a computer’s network connections as it examines both incoming and outgoing data packets. Q. What are firewall profiles? A. Windows Firewall profiles relate to connection types. There are three […]

Adding Replication Partners On large networks that require the WINS service, you should deploy more than one WINS server. These servers can then share the WINS database information as replication partners. This provides load balancing for the WINS database and also helps conserve bandwidth across slower WAN connections. (A single WINS server would tie up […]

Working with Connection Security Rules Inbound and outbound rules control the movement of data to and from a particular computer (say a server) on the network (as already discussed). The Windows Firewall also offers connection security rules, which are used to control authentication between two computers (say two network servers) so that any connection established […]

Understanding IPSec The IP Security Protocol (IPSec) is a suite of cryptography-based protection services and security protocols that can be used to secure internal networks and can also be used to secure remote access connections such as a VPN. IPSec secures the data even if the routers and other devices involved in moving the data […]

Summary The Windows Firewall monitors the state of the computer’s network connections and examines incoming and outgoing data traffic. Basic settings for the Windows Firewall can be configured in the Windows Firewall Settings dialog box, which is accessed via the Windows Control Panel. More advanced settings for the Firewall, including the creation of inbound, outbound, […]

Understanding Windows Firewall Rules The Windows Firewall allows or denies network traffic based on the rules that have been created and configured for the firewall. You can create three types of rules: inbound rules, outbound rules, and connection security rules. Let’s look at inbound and outbound rules and then at connection security rules, which are […]

Creating Windows Firewall Rules You can create new inbound or outbound rules as needed. The New Inbound (or Outbound) Rule Wizard walks you through the steps of creating your new rule. Follow these steps: 1. Select the Inbound Rules or Outbound Rules node in the Windows Firewall with Advanced Security snap-in. 2. In the Actions […]

Configuring WINS Clients Another aspect of WINS is configuring WINS clients so that they use the service for NetBIOS name-to-IP resolution. Any Microsoft Windows client or server can be configured as a WINS client. And although each client operating system is configured for WINS in a slightly different way, you are basically providing the client […]

Using NBTSTAT A useful command-line tool related to this discussion of NetBIOS and WINS is NBTSTAT. NBTSTAT can be used to determine whether the client’s NetBIOS names are registered in the WINS database. It can also be used to release and renew a computer’s NetBIOS names registered with the name server and to show a […]

Summary In this hour, you learned how to install and configure the WINS service. NetBIOS is used by legacy Windows client operating systems and legacy applications to identify resources on the network. NetBIOS names must be resolved to IP addresses by these clients, which use broadcast messages for the resolution. The Windows Internet Naming Service […]
