I’m a big proponent of the SMTP relay concept. A properly configured SMTP relay can protect your Exchange Server by preventing untrusted SMTP servers on the Internet from directly communicating with your Exchange server. An SMTP relay doesn’t require a significant amount of system resources and you can install the IIS SMTP service without incurring the resource or security overhead you would have if you installed the IIS W3SVC (World Wide Web service).In this article we'll go over some of the important details you need to consider before rolling out an SMTP relay to complement your ISA 2004 firewall e-mail protection design.
In this document, we will go over detailed procedures required to configure Microsoft Exchange Servers and the ISA Server 2004 firewall to support the front-end Exchange Server on a trihomed DMZ segment and the back-end Exchange Server on the Internal network. We've got a lot of ground to cover, so get started now and you'll be done by the end of the week!
Name resolution is an essential component of networking. One of the most common reasons for connectivity issues between the ISA Server 2004 clients at branch offices and hosts at the main office are DNS related issues. DNS name resolution issues can prevent hosts on branch office networks from connecting to resources on the main office network, and can also prevent access to Internet-based resources. Name resolution issues can also interfere with main office services access to resources on the branch office networks. This article provides you with solutions to your DNS woes and takes the mystery out of the Split DNS infrastructure.
We’ve been working hard on updating the ISA Server Deployment Kits over the last few months. I’m happy to report that the ISA Server 2004 VPN and ISA Server 2004/Exchange Deployment Kits have been finished. The ISA Server 2004 Branch Office Deployment Kit is in development now and we expect to have those ready for you this month. The ISA Server 2000 Deployment Kits have been enormously popular, so it would have been a crime not to update them!
There are a couple of things I’d like to ask everyone in the ISAServer.org community about before we get to updating the Branch Office Kit and the SharePoint Portal Server kit.
While no one knows when ISA Server 2004 will be officially released to the public, there is going to be a lot of ISA Server 2004 activity at the upcoming TechEd conference in San Diego this month. In fact, I’ll be there too! It would be great to meet up with ISAServer.org members at TechEd so that we can share tips, tricks and secrets with each other.
