WOW64 indicates that the Management Tools are supported in WOW64, a feature of 64-bit editions of Windows that enables 32-bit applications to run natively in 32-bit mode. Software Requirements As part of the SQL Server 2008 software installation wizard, a validation process performed by System Configuration Check routinely scans the server for conditions that might block the setup or installation process. Pre-installing .NET Framework 3.5, Microsoft Installer 4.5, and Windows PowerShell 1.0 will minimize or avoid a system reboot or errors on installation. All of these can be downloaded from the Microsoft download site, www.microsoft. com/downloads. Microsoft Internet Explorer 6 SP1 or later will be required for the installation process. Internet Explorer is required by SSMS, BIDS, Reporting Services’ Report Designer, HTML Help, and Microsoft Management Console (MMC). Establishing Service Accounts The selection of the installation account and the service accounts is part of the installation planning. The most common scenarios for the installation account privileges include: For local installations, the installation account must have Administrator  privileges. For installs where the installation software is on a remote share, the  installation account must be a domain account with Administrator privileges, and read and execute permissions on the remote share. For installations on clusters, the installation account must be a local  administrator on the cluster with permissions to log in as a service on the cluster. Each service in SQL Server must have an account configured during installation. Service accounts used to start and run SQL Server can be built-in system accounts, local user accounts, or domain user accounts. Microsoft recommends that service accounts be configured such that SQL Server services are granted the minimum permissions to complete their tasks. SQL Server 2008 service accounts are described in the following list: InstallingSQLServer2008•Chapter2 61  Domain user account If the service must interact with network services, access domain resources such as file shares, or use linked server connections to other computers running SQL Server, you might use a minimally privileged domain account. Many server-to-server activities require a domain user account. The domain accounts must exist prior to the installation process, unlike when using local accounts.  Local user account A local user account without Windows Administrator permissions is recommended if the computer is not part of a domain.  Local service account An account that is a built-in account (also known as an “NT AUTHORITY\Local Service account”) and has the same level of access to resources and objects as members of the Users group. These restricted privileges help safeguard the system if individual services or processes are compromised, but they are not supported for SQL Server or SQL Server Agent services.  Network service account (“NT AUTHORITY\NetworkService”) The network service account is a built-in account that has more access to resources and objects than members of the Users group. Services that run as the network service account access network resources by using the credentials of the computer account.  Local system account (“NT AUTHORITY\System”) A very high-privi- leged built-in account that has extensive privileges on the local system and acts as the computer on the network. In addition to having user accounts, every service has three possible startup states that users can control:  Disabled The service is installed but not currently running.  Manual The service is installed, but will start only when another service or application needs its functionality.  Automatic The service is automatically started by the operating system. The administrator account used during the installation process enables the setup process to create local service user groups for the different SQL Server services, and assigns the service account or service SIDs to the appropriate local service group. The service user groups help secure the SQL Server files, as well as simplify the process of granting permissions required by the service. Table 2.10 summarizes the account types that can be used for each SQL Service, as well as user groups and permissions created by the SQL Server installer. . such that SQL Server services are granted the minimum permissions to complete their tasks.
