Managing the Edge Transport Server • Chapter 7 387 DNS servers by taking Properties for the Edge Transport server object in the Result pane. On the Properties page, click the External DNS Lookups tab and specify the DNS server that should be used for routing mail to other SMTP servers on the Internet (see Figure 7.9). Figure 7.9 External DNS Lookups Installing the ADAM Component Since the Edge Transport server role uses ADAM directory service as the repository for the replicated confi guration and recipient data, it should come as no surprise that you’ll need to install ADAM before you can install the Edge Transport server role. If you plan to install the Edge Transport server role on a Windows 2003 R2 server, you can install the component via Add or Remove Programs | Add/Remove Windows Components | Active Directory Services, where you need to tick Active Directory Application Mode (ADAM), as shown in Figure 7.10. Next, click OK twice. 388 Chapter 7 • Managing the Edge Transport Server Figure 7.10 Adding the ADAM Component To install ADAM on a Windows 2003 server with SP1 or later will require downloading the ADAM installation package by clicking Active Directory Application Mode in the Downloads section under the following link: www.microsoft.com/windowsserver2003/adam. Managing the Edge Transport Server • Chapter 7 389 Installing .NET Framework 2.0 and Windows PowerShell As is the case with any other Exchange 2007 Server role, you also need to install both the .NET Framework 2.0 component as well as Windows PowerShell, which we showed you how to do in Chapter 3. Saying Goodbye to the Windows SMTP and NNTP Protocol Stacks As most of you might recall, Exchange Server 2000 and 2003 extended and made use of the Windows Server 2000 or 2003 SMTP and NNTP services and thus required you to install both the Windows NNTP and the SMTP components (which both are part of IIS) prior to installing the Exchange Server product itself. Since NNTP is one of the features that aren’t supported in Exchange Server 2007, you need to make sure that this component isn’t installed on the server. If it is, the Exchange Server 2007 readiness check will fail. In addition, because Exchange Server 2007 no longer uses the Windows Server SMTP service but instead has its own, which has been written from the ground up in managed code, you also need to make sure that the Windows Server SMTP component isn’t installed on the server. As with NNTP, the Exchange Server 2007 readiness check will fail if this component is found on the server. You might ask why the Exchange Product Group replaced the Windows SMTP component with its own. Well, by doing so, the Exchange Product Group has reduced the risks that are associated with DoS attacks, eliminated the dependency on IIS, and reduced the work required to properly secure the server for deployment in the perimeter network (the DMZ or screened subnet). Installing the Edge Transport Server Role Now you can begin the actual installation of the Exchange 2007 Edge Transport server role. As is the case with all the other Exchange Server 2007 roles, you install this role by performing the following steps: 1. Navigate to the Exchange Server 2007 source directory (DVD media or the network share containing the Exchange Server 2007 binaries). 2. Double-click Setup.exe. 3. When the Exchange Server 2007 setup splash screen appears, click Step 4: Install Microsoft Exchange. SOME INDEPENDENT ADVICE Although we’re using the Exchange Server 2007 Installation Wizard to install the Edge Transport server role, you can, as we stated in Chapter 3, also install this server role in unattended mode. To do so, you need to execute a command similar to the following: Setup.exe /mode:Install /role: ET. The MMC 3.0 component will only appear as installed if you’re installing Exchange Server 2007 on a Windows Server 2003 R2 edition. If you’re installing the Edge Transport server role on a Windows 2003 server with SP1 or later applied, you need to download and install MMC 3.0 manually. 390 Chapter 7 • Managing the Edge Transport Server 4. When the Exchange Server 2007 Installation Wizard has initialized, click Next. 5. Accept the End User License Agreement (EULA) and click Next. 6. You now have the option of enabling Error Reporting (which is recommended so that the Exchange Product Group receives information about any issues you encounter; in the end this information will give us a better product). When you have decided whether you want to enable error reporting or not, you can click Next. 7. Since you’re going to install the Edge Transport server role, you now need to choose Custom Exchange Server Installation and then click Next (see Figure 7.11). This is also the screen where you have the option of changing the path for the Exchange Server installation (in the bottom of the screen).
