Introducing Microsoft Windows Longhorn Server

We type net stop dens; we can now stop the DNS Server service without getting an error because the service is now present on the machine. Now that our machine is a DNS Server, we can use the dnscmd.exe command to further configure this role if we want from the command line.

Installing other server roles is similar to what we just did and uses the ocsetup.exe command,
With the exception being that the process installs the Active Directory role. This is because Dcpromo.exe in Windows Server 2008 now installs the Active Directory binaries during pro- motion and uninstalls the binaries during demotion, so you should not use ocsetup.exe to add   or remove the Active Directory role as then the promotion/demotion will not take place and your server may not function correctly.

Anyway, to add or remove the Active Directory role, you therefore have to use the dcpromo.exe
Tool, but you also have to run it in unattended mode because the GUI form of this tool (the Active Directory Installation Wizard) can’t run on a Windows server core server because of the lack of a desktop shell to run it in. The syntax for running dcpromo.exe in unattended mode is dcpromp /unattends: unattend.txt, and a sample unattend.txt file you could use (or further customize) for doing this is as follows:

Installing Optional Features

Installing optional features is very similar to installing roles .Type oculist to display a list of installed and uninstalled features and to determine the internal name of each feature. For example, the Failover Cluster feature is named Failover Cluster-Core, and we need to use this internal form of the name when we run ocsetup to install this feature. You can also remove features by adding and /uninstall switch to your ocsetup command. You can remote roles that way too, but be sure to stop the role’s services before you remove the role

Other Common Management Tasks

There are lots of other common management tasks you might need to perform on a Windows server core server. The following is just a sampling of some of these tasks. First, you can add new hardware to your server. Windows server core servers include support for Plug and Play. So if your new device is PnP and there’s an in-box driver available for your device, you can just plug the device in and the server will recognize it and automatically install a driver for it. But we did mention earlier that the Windows server core server installation option of Windows Server 2008 does not include that many in-box drivers. So what do you do if your device is not supported by an in-box driver because of its date of manufacture?
