Download and install the Ms12tp.exe on the clients. c. You must upgrade the clients to Windows 2000 Professional or Windows XP. d. Install a Connection Manager package to deliver the L2TP/IPSec client.

When using query execution times as a performance metric, it is typically a good idea to execute each query a few times and use either the lowest execution time or the median as the metric. Also, note that metrics in a test environment might not accurately reflect performance in a production environment. This depends on a number of factors, including how users actually interact with real-life data.

You can use the following questions to test your knowledge of the information in Lesson 2, Configuring the Global Catalog and Application Directory Partitions. The questions are also available on the companion CD if you prefer to review them in electronic form.

Whereas the domain, configuration, and schema partitions of the directory are replicated to all DCs in a domain, and the configuration and schema are further replicated to all DCs in the forest, Active Directory also supports application directory partitions. An application directory partition is a portion of the data store that contains objects required by an application or service

The WMI Event Registration Tool enables you to create, display, and modify the event consumers, filters, and timers for a given namespace and any bindings between filters and consumers. You can use the tool to do the following:

If at all possible, you should try to reduce the use of server-side cursors. For those cases where a cursor is determined to be the best solution, you need to consider ways to maximize cursor performance. This section highlights a few methods you can use to accomplish this goal.

For all Windows operating systems, the amount of RAM supported is greater in its 64-bit version than in its corresponding 32-bit version. Only 64-bit operating systems can fully address beyond 4 GB of RAM. The /3GB boot.ini switch restricts kernel mode usage to 1 GB and boosts to 3 GB the amount of process address space available for applications such as SQL Server.

5. If available in the Input Settings area, select the Turn Off Advanced Text Services For This Program check box. Advanced Text Services can interfere with earlier software, especially games. 6. Click OK, and then start the program and verify that it runs properly.

To configure ISA Server authentication, use the following procedure: 1. In the ISA Server Management Console, click Virtual Private Networking. 2. On the Tasks tab, click Select Authentication Methods.

SQL Server 2005 Books Online recommends that you perform your monitoring on a monitoring server rather than on the SQL Server 2005 production server that you want to monitor. In practice, this philosophy is debatable. If the Performance tools run on a remote system, Distributed Component Object Model (DCOM) calls have (arguably) more impact on network resources than does logging all counters directly on the production server.
