In most cases, Dell PowerEdge servers are shipped with the Operating System pre-installed. Except if it has been optionally ordered, the Windows Server media is not included in the package.If you want to reinstall a Windows Server OS on your PowerEdge, but you lost or don't have the original Windows installation media at hand, you can download the matching ISO-file directly from the Microsoft website (after filling the registration form).These versions will start in trial mode and can be activated with an OEM Serial Key.

An automatic updater of untrusted certificates is available for Windows Vista, Windows Server 2008, Windows 7, and Windows Server 2008 R2. This updater expands on the existing automatic root update mechanism technology that is found in Windows Vista and in Windows 7 to let certificates that are compromised or are untrusted in some way be specifically flagged as untrusted. A certificate trust list (CTL) is a predefined list of items that are signed by a trusted entity. All the items in the list are authenticated and approved by a trusted signing entity. This update expands on this existing functionality by adding known untrusted certificates to the untrusted certificate store by using a CTL that contains either their public key or their signature hash. After this update is installed, customers benefit from quick automatic updates of untrusted certificates. Users who have disconnected systems will not benefit from this feature improvement. These customers will still have to install the root certificate updates when they are made available. Please see the \"More Information\" section.As part of this update, the URLs that are used for contacting Windows Update to download the untrusted and trusted CTLs were changed. This could cause problems for enterprises that hardcode these URLs in their firewalls as exceptions.The following are the new URLs:
Users who have disconnected systems can install this update. But those users do not receive a benefit from the update. In fact, installing this update may cause service startup failures immediately after the server is restarted. Services that perform certificate validation tasks during service startup may experience an increased delay while network retrieval of the trusted and untrusted CTLs from Windows Update is tried. For systems that are running Windows Vista, Windows 7, Windows Server 2008, or Windows Server 2008 R2 and that are using the automatic updater of untrusted certificates (that is, if either KB 2677070 or KB 2813430 is already installed), see the rest of this section and also Microsoft Knowledge Base article 2813430 for more information. Customers do not have to take any action because these systems will be automatically protected.If the system does not have access to Windows Update, either because the system is not connected to the Internet or because Windows Update is blocked by firewall rules, the network retrieval will time-out before the service can continue its startup procedure. In some cases, this network retrieval time-out may exceed the service startup time-out of 30 seconds. If a service cannot report that startup has completed after 30 seconds, the service control manager (SCM) stops the service. If you cannot avoid installing this update on disconnected systems, you can disable the network retrieval of the trusted and untrusted CTLs. To do this, you disable automatic root updates by using Group Policy settings. To disable automatic root updates by using policy settings, follow these steps:
Windows Server 2008 R2 and later server operating systems are not available as 32-bit architectures. All supported server operating systems are only available as 64-bit. All features are supported on 64-bit server operating systems.
Windows Server 2008 Standard. This version has built-in, enhanced Web and virtualization capabilities, powerful tools that give customers greater control over their servers and streamline configuration and management tasks, and enhanced security features that work to harden the operating system to help protect their data and network and provide a solid, highly-dependable foundation for businesses. With Windows Server 2008 Standard edition, customers get one virtual instance per license.
Windows Web Server 2008. Designed to be used as a single-purpose Web server, Windows Web Server 2008 delivers a rock-solid foundation of Web infrastructure capabilities in the next-generation Windows Server 2008. Integrated with the newly re-architected Internet Information Services (IIS) 7.0, ASP.NET, and the Microsoft .NET Framework, Windows Web Server 2008 helps enable any organization rapidly deploy Web pages, Web sites, Web applications and Web services.
All will be available in 32-bit or 64-bit versions, with the exception of Windows Server 2008 for Itanium-based Systems, which will only be available as a 64-bit version. Other changes include the availability of Windows Web Server 2008, a 64-bit edition of Web server. The Hyper-V feature will only be available with 64-bit editions of Windows Server 2008.
In response to industry and customer demands for more comprehensive technical support of virtual machines, Kelly also announced the Server Virtualization Validation Program. Beginning in June 2008, vendors will be able to self-test and validate certain technical requirements of their server virtualization software running Windows Server 2008 and prior versions. The program will enable Microsoft to offer cooperative technical support to customers running Windows Server on validated, non-Windows server virtualization software. 076b4e4f54
