5. Modify the Text property of the tsbSearch button to Search. Change all your other controls to meaningful names. 6. For each button, add the respective functionality. (You ll see how easy it is to add the desired functionality because the WebBrowser control was well designed to provide methods for the most important functionalities.) Double-click one button after the other, and you ll get to the Click event for each one. In each Click event, add the code in Table 6-3, which lists the corresponding button name and event source code. Button Name tsbBack tsbForward tsbStop tsbRefresh tsbHome tsbSearch Event Code myBrowser.GoBack() myBrowser.GoForward() myBrowser.Stop() myBrowser.Refresh() myBrowser.GoHome() myBrowser.GoSearch()

between the two can be established. If the ARP broadcast fails to determine the physical address of the target computer s network adapter, an error message is generated. See also MAC address. Advanced Digest Authentication Advanced Digest Authentication is a lightweight process that permits secure authentication of users across network security devices (such as firewalls). It does not require client-side software and does not send user credentials in a clear-text format over public networks. IIS supports Advanced Digest Authentication. AppleTalk AppleTalk is a networking protocol developed by Apple Computer, Inc. for communication between Apple Macintosh computers. authentication The process of verifying the identity of a user or computer to grant access to the local computer or network resources. Authentication is typically performed by checking a user name and password, often in conjunction with other security protocols, such as EAP and MS-CHAP. Automatic Private IP Addressing (APIPA) A service that automatically assigns IP addresses to network clients when no DHCP server is available. When a Windows 2000 or Windows XP computer starts up, it makes a DHCP query in an attempt to get a network address. If the DHCP server fails to answer, APIPA is used by the client to assign an IP address in the range of 169.254.0.1 to 169.254.255.254. This particular range of addresses was set aside for use by the Internet Assigned Numbers Authority (IANA) for use only on private, internal networks.

IPSec creates a new IP header for a packet that can be routed as normal IP traffic. Routers and switches in the data path between the communicating hosts simply forward the packets to their destination. However, when a firewall or gateway lies in the data path, you must create firewall rules that allow traffic on the following IP protocols and UDP ports:

Create inbound and outbound filters to allow IKE traffic to be for-

warded. Because of the nature of the NAT and port address translation (PAT) technologies, which require that packets be altered to change IP address and port information, IPSec is not compatible with NAT. IPSec does not allow manipulation of packets during transfer. The IPSec endpoint will discard packets that have been altered by NAT because the ICVs will not match. Windows Server 2003 does allow IPSec ESP to pass NAT routers but encapsulates the IPSec-protected packet inside a UDP packet through a technology called NAT-T. NAT-T was added to Windows XP in Service Pack 2. Additionally, an L2TP/IPSec client that supports NAT-T for Windows 2000 can be downloaded from the Microsoft Web site at http://support.microsoft.com/kb/818043.

bridge A hardware device (or piece of software) that connects two physically dissimilar networks, such as an Ethernet network and a Token Ring network, or an Ethernet network and a wireless network. Windows XP includes a feature known as Network Bridge that can function as a software bridge.

You can monitor IPSec in Windows 2000 with IPSecmon.exe and in Windows Server 2003 and Windows XP using the IP Security Monitor Microsoft Management Console (MMC) snap-in. In addition, you can create log files in Windows Server 2003, Windows 2000, and Windows XP to view IPSec negotiations.
