Figure 2-5 shows these constraints applied to our sample diagram. For example, you can now read the first relationship (between Inventory and Product) as, The inventory has one or more products and each product is in a single inventory. This gives you a very good understanding of your system in terms of objects and the facts that exist between those objects.

The domain naming role is used when adding or removing domains in the forest. When you add or remove a domain, the domain naming master must be accessible, or the operation will fail.

When a package is executed from the command line, the package will always execute at the location from which DTExec is run not the location at which it is stored. SSIS packages can be located on remote file shares or remote SQL Servers, but the package will execute where the DTExec statement is located.

Modify the default system policy settings to match your organization s requirements. First, identify the functionality that you require on the ISA Server computer. Then review the system policy settings and disable all the system policy rules that you do not require. For example, if no users will ever access ISA Server using Remote Desktop, then disable the Terminal Server system policy that enables Remote Desktop connections. Second, for the system policy rules that you leave enabled, you should limit which networks are included in the system policy setting. For example, by default, the DNS system policy allows ISA Server to perform DNS lookups on any connected network. If you want the ISA Server computer to be able to perform lookups only on the Internal network, then modify the system policy setting. You can limit the scope of some system policy rules even more. For example, Remote Desktop connections are permitted only from the computers listed in the Remote Management Computer set. You should add the IP addresses for the computers used by the ISA Server administrators to this group, rather than allow access based on a network. To modify the default system policy, use the following procedure: 1. In the console tree of ISA Server Management, click Firewall Policy. 2. On the Tasks tab, click Edit System Policy. The interface is shown in Figure 3-2.

Bandwidth Usage. This option is only available to the host. The bandwidth usage options are discussed further in Table 8-1. Chat A basic text-based chat program through which the helper and host can send comments to each other. Send File Allows files to be transmitted. Help Brings up help and support. The process of preparing a Remote Assistance invitation to connect to a remote computer is covered in detail in Practice 2 at the end of this lesson.

Configure, Manage, and Troubleshoot Encrypting File System (EFS)

Businesses must be able to control who can access confidential data. For example, an expense-tracking application should show users their own expenses, but only managers should be able to view other people s expenses. Unauthorized users should not be able to view any of the data even if they manage to bypass your application s builtin protection. Protecting data requires coordinating several different technologies. Role-based security (RBS) allows you to control what users can access based on their user name and group memberships. With the .NET Framework, you can make RBS decisions based on the local user database, an Active Directory domain, or a custom user database. You can also use the .NET Framework to configure access control lists (ACLs). ACLs are the operating system s method for tracking who should have access to what, and determining which actions require adding an event to the event log. Finally, to protect data if an attacker bypasses operating system security, the .NET Framework provides cryptography tools for encrypting, validating, and signing data.

Secure Sockets Layer (SSL) is used to validate the identities of two computers involved in a connection across a public network, and to ensure that the data sent between the two computers is encrypted. To do this, SSL uses digital certificates and public and private keys. SSL enables the following features:
