Figure 7-18: Remote Desktop Users You will configure Remote Desktop in the practice at the end of this lesson Remote Assistance Both Remote Assistance and Remote Desktop allow the user at the management computer to see the desktop and applications that are present on the remote computer The difference between Windows Remote Assistance and Remote Desktop is that a user is logged on to the remote computer and initiates the remote assistance session, whereas a Remote Desktop session is initiated on the management computer Remote Assistance is a support tool used by help-desk staff to allow them to view the screen of the person to whom they are providing assistance Remote Assistance reduces the need for nontechnical users to accurately describe the problem that they are having with their computers because support personnel can see the desktop directly.

The ability to return result sets from triggers will be removed in a future version of SQL Server. Triggers that return result sets might cause unexpected behavior in applications that are not designed to work with them. Avoid returning result sets from triggers in new development work, and plan to modify applications that currently do this. To prevent triggers from returning result sets in SQL Server 2005, use the sp_configure system stored procedure to set the Disallow Results From Triggers option to 1. The default setting of this option will be 1 in a future version of SQL Server.

Director of Customer Relations Several of our high-usage customers want access to functionality within our internal applications. I m not a developer, but after meeting with the customers, I think the consensus is that they want to use Web services to query our internal applications for current pricing and availability of high-capacity power. I want them to be able to do that, but I m more than a little scared about exposing our applications to the Internet. Partner Relationship Manager We work closely with other power companies to exchange capacity as needs shift. Today, that s a manual process involving a phone call, negotiations, and one of our employees clicking some buttons in your application. We could realize a great deal of efficiency if we could automate this with Web services. After talking about it with your manager, I know it can be done, but I also know he s concerned that someone could misuse our application to take over our systems or some such nonsense. End User Whatever you do, don t make me learn any new passwords.
