1. Managing Identity Information Between LDAP Directories and Exchange Server 2007
LDAP directories are commonplace today and can be found in many business environments. UNIX applications in particular make wide use of the LDAP standard for directories. Along with this proliferation of LDAP directory structures comes a need to synchronize the information contained within them to an Exchange 2007 environment. The Enterprise version of MIIS 2003 contains MAs that support synchronization to LDAP directories. Consequently, a good understanding of LDAP concepts is required before syncing between the environments. ...

2. Understanding DNS Requirements for Exchange Server 2007
In Active Directory, all client logons and lookups are directed to local domain controllers and GC servers through references to the SRV records in DNS. Each configuration has its DNS and resource requirements. Exchange relies on other servers for client authentication and uses DNS to find those servers. In an Active Directory domain controller configuration, on the other hand, the Exchange server also participates in the authentication process for Active Directory. Using DNS in Exchange Server 2007 As has bee...

3. Securing and Maintaining an Exchange Server 2007 Implementation
One of the greatest advantages of Exchange Server 2007 is its emphasis on security. Along with Windows Server 2003, Exchange Server 2007 was developed during and after the Microsoft Trustworthy Computing initiative, which effectively put a greater emphasis on security over new features in the products. In Exchange Server 2007, this means that the OS and the application were designed with services “Secure by Default.” With Secure by Default, all nonessential functionality in Exchange must be turned on if needed. Thi...

4. Improvements in Exchange Server 2007 Relative to Security and Compliance
One of the improvement goals Microsoft has had with all of their products over the past few years has been to constantly improve the security in the products. More recently with all of the regulatory compliance laws and policies being implemented, Microsoft has focused a lot of security enhancements to address privacy, information archiving, and compliance support. The release of Exchange 2007 was no different—Microsoft added in several new enhancements in the areas of security and compliance support. One of the addition...

5. Designing Exchange Infrastructure
After Active Directory and the physical OS has been chosen and deployed, the Exchange infrastructure can be set up and optimized for the specific needs of the organization. With these needs in mind, you can do several things to optimize an Exchange 2007 setup, as detailed in the following sections. Determining the Exchange Version When installing Exchange, the choice of Exchange version needs to be made. As with Windows Server 2003, there are two versions of Exchange, Standard and Enterprise. The Standard Edit...

6. Synchronizing Exchange Server 2007 with Novell eDirectory
Novell eDirectory and Novell Directory Service (NDS) environments are relatively commonplace in business environments, and there is often a need to integrate them into deployed Exchange infrastructures. Several tools exist that can make this a reality, including the MIIS 2003 tools discussed. In addition, tools in the Microsoft-supplied Services for NetWare can be used to synchronize directory information between the two directory systems. NOTE Exchange 2000 Server and Exchange Server 2003 included a GroupWise ...

7. Integrating Client Access into Exchange Server 2007 Design
Although the Exchange server is a powerful systems component, it is only half the equation for an email platform. The client systems comprise the other half, and are a necessary ingredient that should be carefully determined in advance. Outlining Client Access Methods Great effort has been put into optimizing and streamlining the client access approaches available in Exchange 2007. Not only have traditional approaches such as the Outlook client been enhanced, but support for nontraditional access with POP3 and...

8. Domain Name System and Its Role in Exchange Server 2007
For computer systems to communicate with each other, whether you are talking about a local area network (LAN), a wide area network (WAN), or the Internet, they must have the ability to identify one another using some type of name resolution. Several strategies have been developed over the years, but the most reliable one to date (and the current industry standard) is the use of a DNS. Accurate name resolution is critical in a mail environment as well. For a message to reach its destination, it might pass through several syste...
