3.Right-click the domain name, and click the New Alias (CNAME) command.

4.In the Alias name (uses parent domain if left blank) text box, enter the name wpad, and click

Browse.

5.In the Browse dialog box, double-click the server name in the Records list, the Forward Lookup Zones entry in the Records list, and then the domain name in the Records list.

6.Select the resource record for the ProLiant DL320 Security Server in the Records list, and then click OK. The name of the ProLiant DL320 Security Server now appears in the Fully qualified domain name (FQDN) for target host text box.

7.Click OK. The WPAD alias entry now appears in the resource record list in the results pane of the DNS console.

DHCP option 252

Use the DHCP option 252 WPAD method for computers using DHCP to obtain IP addressing information. Requirements for this option include:

•A DHCP server on the LAN

•Computers on the LAN use DHCP to obtain IP addressing information

•Web proxy client users logged on as local administrators or members of the Power Users group

If a DHCP server exists on your LAN:

1.From the Administrative Tools menu on the DHCP computer on the LAN, open the DHCP console.

2.In the scope pane of the DHCP console, right-click the server name, and click Set Predefined

Options.

3.In the Predefined Options and Values dialog box, click Add.

4.In the Option Type dialog box in the Name text box, enter WPAD.

5.Select String in the Data type list, enter 252 in the Code text box, and enter DHCP wpad entry in the Description text box.

6.In the Predefined Options and Values text box, enter the following information in the String text box, where computer_name is the DNS name of the ProLiant DL320 Security Server and AutoDiscoveryPortNumber is the port number that the server uses to publish automatic discovery information, TCP port 80 by default:

http://<computer_name>:<AutoDiscoveryPortNumber>/Wpad.dat

7.In the Predefined Options and Values dialog box, click OK.

NOTE: To perform DHCP automatic discovery, you must be logged on as an administrator or Power User in Microsoft® Windows® 2000 or as an administrator, Power User, or member of the Network Configuration Operators group in Microsoft® Windows® XP. For more information, refer to the "Automatic Proxy Discovery in Internet Explorer with DHCP Requires Specific Permissions" article on the Microsoft website (http://go.microsoft.com/fwlink/?LinkID=27334).

Configuring time synchronization

Use the firewall as a time server for the LAN. A time server is a computer that provides accurate time to other computers on the LAN. This server increases security on the network by providing accurate time to all hosts on the network so that auditing and logging entries have the correct time. In addition, many network protocols require accurate time to function properly.

To obtain the most accurate time possible, the ProLiant DL320 Security Server must access a time server on the Internet. If you choose not to have the ProLiant DL320 Security Server as a time server for the LAN, configure the server to allow computers on the LAN to contact their own Internet time servers.

Microsoft Internet Security and Acceleration (ISA) Software specifications

HP Microsoft Internet Security and Acceleration (ISA) Software is a robust network security solution designed to safeguard business environments by offering a versatile platform for secure internet access. ISA Server integrates multiple functionalities that are essential for modern enterprise needs, helping organizations manage and protect their network infrastructure.

One of the main features of ISA Server is its firewall capabilities, which provide an essential barrier between internal networks and external threats. The software utilizes intelligent packet filtering to analyze incoming and outgoing traffic, ensuring that only legitimate communications are allowed while blocking potentially harmful activity. This helps to mitigate risks associated with external cyber threats and unauthorized access.

Another key feature is the built-in web caching technology. ISA Server improves network performance by caching frequently accessed websites and content. This reduces bandwidth usage and enhances response times for end-users, leading to increased productivity. By storing copies of web pages, ISA Server can serve them quickly to users, allowing enterprises to optimize their use of internet resources.

ISA Server also includes a powerful Virtual Private Network (VPN) feature, enabling secure remote access for employees. This technology supports secure connections over the internet, allowing users to access the corporate network and resources from anywhere in the world. The VPN capabilities ensure data encryption during transmission, protecting sensitive information from interception.

Moreover, ISA Server incorporates integrated threat management tools, which offer insights into potential security issues. These tools provide logging and reporting features that allow administrators to monitor traffic patterns and detect anomalies. This functionality is critical for identifying and responding to potential security breaches in real-time.

In addition to these features, ISA Server supports application-layer filtering, which enhances security further. This allows organizations to control access to specific applications and services while ensuring that malicious content cannot infiltrate the network.

Overall, HP Microsoft Internet Security and Acceleration Software is a comprehensive solution designed to address the complexities of network security in today’s digital landscape. Its combination of firewall protection, web caching, VPN capabilities, and application-layer filtering makes it an invaluable tool for organizations looking to secure their internet connectivity while optimizing performance and user experience. By leveraging advanced technologies and characteristics, ISA Server empowers businesses to operate safely and efficiently in an interconnected world.
