Understanding Why ISA Server re-prompts for Authentication when Passwords Expire

Introduction

There are times that the user does not change their password on the day that Group Policy forces a password change. Normally, if the user logs off and tries to logon again, Windows will inform him that his password is expired and require him to change it. ISA is not able to perform the same action as Windows.

This article describes what happens when the user’s domain password expires while he is trying to browse Internet through ISA Server and ISA Server uses a rule that requires authentication.

Overview of Forefront Threat Management Gateway Beta 1

1. Introduction

The Microsoft Forefront Threat Management Gateway promises to be the milestone that all ISA Server admins were waiting for. I heard all the time people saying that the difference between ISA Server 2004 and ISA Server 2006 were not that big and that we pretty much have the same product for 4 years already. Well, that isn’t really true; there are indeed many differences between 2004 and 2006. Maybe some people were waiting for a huge upgrade like it was from ISA 2000 to 2004 and this didn’t happen. After two years since ISA Server 2006 was released, we have now (without a doubt) a big change, maybe will not be noticeable now but it will in the final version.

You can download the beta version from here and use the installation guide article that my friend Tom Shinder wrote. This beta version available for download has only a limited set of features. However, before install read the release notes to see what you can and what you cannot do.

There are many things that you will notice and see that it is different from ISA Server 2006. As far as installation is concern there are some things that you need to remember:

· IIS will be installed: that’s correct; IIS now will be installed by TMG. You might be thinking: “I remember that we have issues with IIS and ISA in the same box…”. You are right for ISA Server, but for TMG we need IIS because TMG needs SQL Reporting Services 2005 and SQL Reporting Services 2005 needs IIS. It is important to emphasize that IIS is not removed if you uninstall TMG.

· 64 bits System: although the final version of TMG requires a 64-bit processor and Windows Server 2008 64-bit, this beta version can be installed in a 32-bit system with Windows Server 2008.

· WEBS: the TMG beta version that we have available for download it will be part of the Windows Essential Business Server. TMG will be available through WEBS Standard and Premium Edition.

Note: The official TMG documentation is available at Microsoft TechNet Library web site.

ISA Server 2006 Service Pack 1 Features

ISA Server 2006 Service Pack 1 Features

Introduction

Microsoft® Internet Security and Acceleration (ISA) Server 2006 Service Pack (SP) 1 will be available for your installation pleasure this summer!

This Service Pack introduces new features and improved functionality for ISA Server 2006 Enterprise and Standard Editions. The new features focus primarily on enhanced troubleshooting mechanisms designed to help you identify and resolve ISA Server configuration issues. Also included in this package are the updates we’ve promised for so long, such as SAN certificate support.

Service Pack 1 new and improved features

ISA Server 2006 SP1 includes the following new features:

· Configuration Change Tracking — logs all configuration changes applied to ISA Server configuration to help you backtrack through your change history.

· Web Publishing Rule Test Button — helps you verify that the rule configuration agrees with what is set at the published web server and provides specific suggestions when they disagree.

· Traffic Simulator — simulates network traffic as it would be seen by the ISA rules engine and gives you specific information about traffic processing along the way.

· Diagnostic Logging Query — an extension to the Diagnostic Logging feature provided in the Supportability Pack, this feature makes it much easier to see only the data that is relevant to the current troubleshooting effort.

ISA Server 2006 SP1 also includes such feature improvements as:

· Support for Network Load Balancing (NLB) multicast and multicast with IGMP operations (KB 938550)

· Support for certificates with multiple Subject Alternative Name (SAN) entries in published web servers

· Kerberos Constrained Delegation (KCD) authentication supports trusted-domain user accounts (KB 942637 )

For additional feature improvements, see "Improvements to existing features" later in this document.

New Citrix Branch Repeater Uses ISA Server

Wednesday, May 21, 2008, 2:43:00 PM | David Burt

Citrix has announced the availability of the new Citrix Branch Repeater, an "all-in-one" device for delivering applications to branch offices.   The Citrix Branch Repeater was developed jointly with Microsoft, and  uses Microsoft ISA Server 2006 Web caching to accelerate delivery of web content to the branch.  ISA Server 2006  helps branch office users easily and securely access the Internet or corporate-based resources. More on ISA's use in the new Citrix Branch Repeater on  Thomas Shinder's ISAServer.org blog here.

Internet Security & Acceleration (ISA) Server,  first launched in 1997 as the Microsoft Proxy Server, is a very versatile product with a great many uses, including as a VPN, a Firewall, a URL filtering proxy, and with Citrix, a Web caching device.   In addition to Citrix, ISA has a rich partner ecosystem that includes providers of URL filters, Anti-Virus, Reporting, User Authentication, and more on our partner page here.

Someone I worked with when I was consulting with Citrix went over to Desktone so I've been watching them.   They came out of stealth mode last month.  Seems that they are really moving along... First they signed up Verizon then they partnered up with HP.  I'm going to keep my eye on them ... Don
