Representation Represents all current network users, including guests and users from other domains. Whenever a user logs on to the network, that user is automatically added to the Everyone group. Represents users currently accessing a given resource over the network (as opposed to users who access a resource by logging on locally at the computer where the resource is located). Whenever a user accesses a given resource over the network, the user is automatically added to the Network group. Represents all users currently logged on to a particular computer and accessing a given resource located on that computer (as opposed to users who access the resource over the network). Whenever a user accesses a given resource on the computer to which they are logged on, the user is automatically added to the Interactive group.

You can select SQL Server Profiler event classes to include in traces that produce estimated and actual execution plans in XML or text. To display execution plan information by using these event classes, you must also include the appropriate Transact-SQL statements to turn on for example, STATISTICS IO or SHOWPLAN_XML. The following event classes are used in SQL Server 2005.

"FILEDSN=c:\dataConn.dsn;Uid=myUid;Pwd=myPwd"

The domain namespace is the naming scheme that provides the hierarchical structure for the DNS database. Each node, referred to as a domain, represents a partition of the DNS database. The DNS database is indexed by name, so each domain must have a name. As you add domains to the hierarchy, the name of the parent domain is added to its child domain (called a subdomain). Consequently, a domain s name identifies its position in the hierarchy. For example, in Figure 13-8, the domain name sales.microsoft.com identifies the sales domain as a subdomain of the microsoft.com domain and microsoft as a subdomain of the com domain. The hierarchical structure of the domain namespace consists of a root domain, toplevel domains, second-level domains, and host names.

Tattoos are a significant problem with System Policy, which versions of Windows before Windows 2000 supported. Tattooing means that policies make permanent changes to the registry. The administrator must explicitly remove those policies. For example, if you create a policy file, which has the .pol extension, and Windows applies its settings to the registry, when you remove the policy file, the settings remain. To remove those policies, you must remove the settings from the registry or edit the policy file to remove the settings.

3. After importing the custom template to a computer and restarting the computer, how could you verify that the appropriate settings were made
