Backup jobs are best run at a time when there is minimal use of the server that is to be backed up. This tends to be at times in the middle of the night rather than during the normal hours that a systems administrator is in the office. Rather than having to come back to work each night at 2:00 A.M., or having to wake up to initiate an early morning Terminal Services connection, the Windows Server 2003 Backup Utility allows the scheduling of backup jobs. A wide variety of scheduling options is available. Jobs can be configured to run when the system starts, when it is idle, when a user logs on, daily, weekly or monthly. Jobs can be configured to run every week, every second week or every 100th week, just as they can be configured to run every day, every second day, or every 100th day. Systems administrators are likely to configure multiple schedules on a server, performing a full backup certain days of the week and performing incremental or differential backups other days of the week. The type of schedule they configure depends on the type of media they use to store the backup sets. Six days of incremental backups after a full backup is going to take less time and less space than six days of differential backups after a full backup.

sysmail_help_queue_sp Displays information about the status and mail queues. You can use this stored procedure to troubleshoot messages that were not received. sysmail_delete_mailitems_sp Deletes e-mail messages permanently from Database Mail tables in the msdb database. These messages can be deleted based on their status or the date on which the message was sent. Attachments of deleted messages are also deleted, but associated logged events must be deleted independently by using sysmail_delete_log_sp. sysmail_delete_log_sp

Printing text is similar to printing graphics. Text is printed through the Graphics .DrawString method, which renders a string in the specified font to the printer. As with rendering text to the screen, to print, you must specify a font for rendering the text, text to render, a Brush object, and coordinates at which to print. For example:

Figure 10-3: The Internet and Corporate Access message As you learned earlier, DirectAccess clients use digital certificates to authenticate with the DirectAccess server. If a computer does not have a valid computer certificate issued by a certificate authority (CA) that the DirectAccess server is configured to trust for the purpose of DirectAccess authentication, it cannot connect successfully. DirectAccess clients and the DirectAccess server almost always receive their certificates from an Active Directory Certificate Services Certificate Authority that is integrated into the domain. This ensures that both client and server trust each other's certificates. To verify that a computer certificate is present and valid on a client running Windows 7, perform the following actions: 1. Open a blank Microsoft Management Console by typing mmc into the In The Search Programs And Files text box. 2. Add the Certificates snap-in for the local Computer account. 3. Navigate to the Certificates (Local Computer)\Personal\Certificates node and verify that the computer has enrolled a certificate for the intended purposes of Client Authentication and Server Authentication, as shown in Figure 10-4.
