Windows Server 2003 and later versions are supported for deployment in Microsoft Azure. For versions that are earlier than Windows Server 2008 R2, there is no Azure Marketplace support, and customers must provide their own images. The ability to deploy an operating system on Microsoft Azure is independent of the support status of the operating system. Microsoft does not support operating systems that are past their End of Support date without a Custom Support Agreement (CSA). For example, Windows Server 2003/2003 R2 is no longer supported without a CSA.
Older versions: Windows Server is available in Essentials, Standard, and Premium editions. Essentials is a scaled down version for 1 to 25 users; both the other editions are based on the Windows Server codebase and include Microsoft Exchange Server mail server , Internet Information Services (IIS) web server , Windows SharePoint Services for collaboration, Microsoft Outlook 2003 email client (not included in 2008), Routing and Remote Access Service (RRAS), Windows Server Update Services for update management across the network, and a Fax server . Up to SBS 2003, the Premium edition also included Microsoft SQL Server , Microsoft Internet Security and Acceleration Server and Microsoft Office FrontPage 2003. SBS 2008 Premium edition will not include ISA Server but will include a Windows Server 2008 license and SQL Server 2008 for running on a second server. Those upgrading to SBS 2008 Premium edition via Software Assurance will be compensated with a free license for the latest version of ISA Server. 
Before I show you how to use the index, there is one last dialog box that I want to talk about. If you right click on the Indexing Service container and select the Properties command from the resulting shortcut menu, you will see the Indexing Service Properties sheet, shown in Figure D. If you look at the figure, you will see that the Generation check box contains two check boxes. The first check box asks you if you want to index files with unknown extensions. Unless you’ve got a good reason for doing so, you should never select this box. By default, the Indexing Service will index things like text files, Microsoft Office documents, and HTML files. If you select this check box, it will attempt to index everything in the directories that you have chosen to index. This includes things like EXE files and DLL files.
