Publishing an OWA Site in a Back to Back ISA Firewall Configuration (Part 1): Date - Jul 26, 2005; Author - Thomas Shinder; Section - Tutorials / Configuration - Security; Remote users can connect to your Exchange Server from virtually any site in the world using the HTTP protocol by connecting to the Exchange Server’s Outlook Web Access (OWA) Web site. Exchange Server 2003 takes OWA to the next level. The Exchange Server 2003 OWA site provides much greater functionality than available with the Exchange 5.5 or Exchange 2000 OWA site, and provides a user experience that is very close to what you get with the full Outlook MAPI client.
Product Review: HP ProLiant DL320: Date - Jul 20, 2005; Author - Thomas Shinder; Section - Tutorials / Product Reviews; In this review we take a look at the HP DL320 hardware ISA firewall. The HP ProLiant DL320 is built on HP’s reliable and high performance DL320 G3 hardware. This sturdy ISA-based hardware firewall is targeted at the experienced ISA firewall administrator who wants a pre-built and pre-hardened ISA firewall delivered to the door, ready to plug in and deploy. The HP DL320 gives you a clean ISA firewall experience by focusing on hardware performance optimization and leaving you the option to install add-in software as you like, something you can’t do with all the ISA hardware firewalls on the market today. In addition, HP throws in a few app and network layer enhancements that are sure to improve your overall network security posture.
Redirecting OWA Users to the Correct Directories and Protocols (Part 2): Date - Jul 19, 2005; Author - Thomas Shinder; Section - Tutorials / Configuration - Security; Part 1 of this two-part series on how to redirect OWA users to the right site and protocol discussed the issues involved with creating redirects for users who enter incorrect URLs or incorrect protocols when accessing the OWA Web site. We also went over the initial configuration steps you can use to perform the redirects. In this, part 2 and final part of the series, we’ll go over the configuration steps from beginning to end and explain the rationale behind the steps. By the time you finish the procedure, users will be able to enter incorrect paths and incorrect protocols and still be redirected to the correct OWA Web site. The end result is fewer Help Desk calls.
Troubleshooting IPSec Tunnel Mode Scenarios: Date - Jul 14, 2005; Author - Clint Denham; Section - Tutorials / Configuration - Security; In this article we’ll take a look at how to troubleshoot a common site to site IPSec tunnel-mode VPN scenario.
Redirecting OWA Users to the Correct Directories and Protocols (Part 1) v.1.1: Date - Jul 12, 2005; Author - Thomas Shinder; Section - Tutorials / Configuration - Security; A frequent request I see on the ISAServer.org Web boards and mailing lists is for information on how to help hapless uses who can’t remember to enter the correct path or protocol to reach the Exchange Server’s OWA site. While it might seem like a simple issue to enter the path https://owa.domain.com/exchange into the Web browser Address bar and press ENTER, long experience tells us that this isn’t the case.
How to Record URL and User Information in ISA 2004 Firewall Logs and Reports: Date - Jul 05, 2005; Author - Thomas Shinder; Section - Tutorials / Configuration - General; One of the most common questions I see on the ISAServer.org Web boards and mailing list is how to get user and URL information in the ISA firewall’s logs and reports. The ISA firewall creates reports using ISA log summaries. The log summaries are derived from the ISA firewall’s Web Proxy filter and Firewall service logs. If you want to see user information and URLs (instead of IP addresses) in the reports, you’ve got to get that information into the logs first.
