At the core of the System.Management namespace is the DirectoryObjectSearcher object, which can programmatically access resources through WMI. This mechanism is extremely easy to use because the syntax mimics that of Structured Query Language (SQL), which most developers are already familiar with. To execute a query using the DirectoryObjectSearcher, the following steps need to be performed: 1. Declare an instance of the ConnectionOptions class, and set the UserName and Password properties. 2. Declare an instance of the DirectoryObjectSearcher class. 3. Declare a ManagementScope object, and set the PathName and ConnectionOptions properties. 4. Create an ObjectQuery object, and specify a query to run. 5. Create a ManagementObjectCollection, and set it to the return value from the DirectoryObjectSearcher s Get method.

In project mode, you make changes while you are disconnected from the server. To test your changes, you need to deploy the changes to an SSAS server for example, you might deploy them to your local SSAS server.

2. Your computer crashes with almost clocklike predictability approximately one hour after each system startup. You suspect an application with a memory leak that is causing the system to run out of memory. How can you use Task Manager to determine which application is causing the problem

You can disable automatic switching between preferred networks to solve the problems that occur when a user is working in an overlap area.

A teacher will not want to change his settings when moving between classes. Always ensure that your users understand the disadvantages of this fix.

The ListPermissions sample application used in the Lesson 2 practice uses this method; examine the source code on the companion CD for a working example.

In this practice, you create two full-text indexes. The first index is on a character-based column. The second index takes advantage of the filters that ship with SQL Server to index a column containing Word documents stored in a varbinary(max) column. 1. If necessary, launch SSMS, connect to your instance, and open a new query window. 2. Create a full-text index on the ProductionDescription column in the Production.ProductDescription table in the AdventureWorks database by executing the following command:
