Exchange SQL And IIS- P166:The following legacy Exchange features have been de-emphasized in Exchange Server 2007. What does that mean? It means that these features are still included in the Exchange product, but they’re not prioritized anymore, and will most likely disappear in the next Exchange release after Exchange Server 2007

802 Chapter 15 • Get Started with IIS 7.0’s Conﬁguration Figure 15.18 Disabling Directory Browsing in Web.conﬁg 12. After disabling refresh Internet Explorer, and you should see a screen similar to the one shown in Figure 15.19.
Get Started with IIS 7.0’s Conﬁguration • Chapter 15 803 Figure 15.19 Testing Directory Browsing Disabled So why is delegation so important in IIS 7.0? First, IIS 7.0 conﬁgurations may now exist side by side with ASP.NET conﬁgurations. This means that Web server and application conﬁgurations can be deployed along with content. Another reason that delegation is so important is that security is not compromised. Administrators can pick and choose the features they make available for modiﬁcation without having to provide system administrator rights to developers or lower level administrators; thus, everyone is more productive and efﬁcient.
804 Chapter 15 • Get Started with IIS 7.0’s Conﬁguration Summary The old metabase was loved by some but hated by most because it was difﬁcult to read and provided no mechanism for delegating to nonadministrators. It has been replaced by the XML conﬁguration ﬁle ApplicationHost.conﬁg, which is easier to read and to conﬁgure. Within the ApplicationHost. conﬁg ﬁle are two important section groups: system.ApplicationHost and system.webServer. The system.ApplicationHost section group includes sections that deﬁne key parameters for a Web server. It holds sections that are used by the WAS service and are therefore deﬁned globally. The system. webServer section group is where all the action is. It contains all the default settings and new features for IIS 7.0. The schema in IIS 7.0 represents the interrelationship between the attributes and elements of each object. In IIS 7.0 the schema is hierarchical and easy to read, just as the ApplicationHost.conﬁg ﬁle is. A major improvement in IIS 7.0 over previous versions is delegation. Developers no longer need to have full administrative rights on the server to customize the behavior of IIS for their sites and applications. System administrators can simply delegate section groups or sections to developers, and then they are able to do the rest, easing the burden on administrators. Solutions Fast Track Introducing ApplicationHost.conﬁg ˛ ApplicationHost.conﬁg offers a level of conﬁguration never before available in IIS ˛ Understanding who (security) can modify which conﬁguration section, ApplicationHost versus WebServer is imperative to deploying a secure IIS 7.0 ˛ Replaces the old hard-to-read metabase. ˛ It is the main conﬁguration ﬁle in IIS 7.0. ˛ From within the ﬁle, administrators are able to delegate to non-administrators. Enabling Delegated Administration in IIS 7.0 ˛ Delegation is a powerful management tool and a much-needed feature in IIS 7.0. ˛ Able to unlock section groups, sections, and attributes. ˛ In xcopy scenarios, delegation is important where administrators simplify global conﬁgurations, allowing distributed and delegated conﬁgurations to exist on a per-site basis, thereby simplifying centralized management. ˛ Delegating administrative capabilities is accomplished in ApplicationHost.conﬁg, and yet some features are already enabled for delegation.
Get Started with IIS 7.0’s Conﬁguration • Chapter 15 805 Frequently Asked Questions Q: What is the difference between ApplicationHost.conﬁg ﬁle and a web.conﬁg ﬁle? A: The ApplicationHost.conﬁg ﬁle is the main conﬁguration ﬁle for IIS 7.0. It holds global information about the server. The web.conﬁg ﬁle is used mostly by developers for applications that need to alter some speciﬁc behavior of IIS. Q: Can anyone change the ApplicationHost.conﬁg ﬁle? A: No. Only Windows system administrators (server administrators) can. Q: What exactly is a section group? A: A section group contains related sections and is used solely for the purpose of a structured hierarchy in a .conﬁg ﬁle. Q: Can you explain what a location tag is? A: Location tags specify path-speciﬁc conﬁgurations and are used for locking and unlocking sections. They are used at various levels of the conﬁguration stack, such as: ApplicationHost. conﬁg, site, virtual directories, physical directories, and ﬁle level.
