Administrative tools (control panel application)

Administrative Tools is the collective name for several advanced tools in Windows, it is a folder in Control Panel that contains shortcuts to the various tools for system administrators and advanced users. In other words, Administrative Tools itself doesn't do anything, it's just a location that stores related programs. The tools in the folder might vary depending on which version of Windows you are using. When you open it:

Many of the tools in this folder, such as Computer Management, are Microsoft Management Console (MMC) snap-ins that include their own help topics. To view specific help for an MMC tool, or to search for an MMC snap-in that you don't see in the following list, open the tool, click the Help menu, and then click Help Topics.

Some of programs you'll find in Administrative Tools include:

• Component Services. [pic]

Component Services is an MMC snap-in used to configure and administer Component Object Model (COM) components, COM+ applications, and more. Component Services is designed for use by developers and administrators.

• Computer Management. [pic]

Computer Management is an MMC snap-in used as a central location to manage local or remote computers by using a single, consolidated desktop tool. Computer Management includes Task Scheduler, Event Viewer, Local Users and Groups, Device Manager, Disk Management, and more, all in a single location. This makes it really easy to manage all the important aspects of a computer. Using Computer Management, you can perform many tasks, such as monitoring system events, configuring hard disks, and managing system performance.

• Data Sources (ODBC). [pic]

The Data Sources (ODBC) link in Administrative Tools starts (opens) ODBC Data Source Administrator, a program used to manage ODBC data sources. Use Open Database Connectivity (ODBC) to move data from one type of database (a data source) to another. Open Database Connectivity (ODBC) is a technology that programs use to access a wide range of databases (or data sources). For example, ODBC can be used to import data from a MySQL database into a Microsoft Excel spreadsheet. To do this, your computer needs the correct ODBC driver and data source.

• Event Viewer. [pic]

Event Viewer is an MMC snap-in used to view information about certain actions in Windows, called events. Events are stored in event logs, of which there are several kinds. It views information about significant events, such as a program starting or stopping, or a security error.

• iSCSI Initiator. [pic]

The iSCSI Initiator link in Administrative Tools starts the iSCSI Initiator Configuration Tool which is used to manage iSCSI network storage devices. It configures advanced connections between storage devices on a network using TCP/IP. It can be used over a local area network (LAN), a wide area network (WAN), or the Internet.

The iSCSI initiator provides connectivity to an iSCSI target device over an Ethernet connection. This allows you to access storage that exists in a different location from your computer. When your computer connects to a disk on an iSCSI target device, the disk appears as a local hard disk that can be managed and accessed like any other local hard disk.

• Local Security Policy. [pic]

Local Security Policy is an MMC snap-in used to manage and edit Group Policy security settings.

• Performance Monitor. [pic]

Performance Monitor is an MMC snap-in that's used to view advanced system information about the central processing unit (CPU), memory, hard disk drive, and network performance.

• Print Management. [pic]

Print Management is an MMC snap-in used as a central location to manage local and network printer settings, installed printer drivers, current print jobs, and much more.

• Services. [pic]

Services is an MMC snap-in used to manage all Windows services, the different services that run in the background on your computer.

• System Configuration. [pic]

System Configuration is a tool that can help identify problems that might prevent Windows from starting correctly. You can start Windows with common services and startup programs turned off and then turn them back on, one at a time. If a problem doesn't occur when a service is turned off, but does occur when that service is turned on, then the service could be the cause of the problem.

System Configuration is intended to find and isolate problems, but it's not meant as a startup management program.

• Task Scheduler. [pic]

Task Scheduler is an MMC snap-in used to schedule a task, a program or other tasks to run automatically at a defined date and time.

• Windows Firewall with Advanced Security. [pic]

Windows Firewall with Advanced Security is an MMC snap-in used for advanced configuration of the software firewall settings on both this computer and remote computers on your network.

• Windows Memory Diagnostic. [pic]

Windows Memory Diagnostic tests your computer's memory when Windows is not running. It checks the memory to see if it's functioning properly.

Component Services Administration

You can use the Component Services snap-in in Microsoft Management Console (MMC) to configure and administer Component Object Model (COM) components, COM+ applications, and the Distributed Transaction Coordinator (DTC).

Component Services is designed both for system administrators and for application developers. For example, administrators can manage components, and developers can configure routine component and application behavior.

Component Services focuses on the administration of COM+ applications. Developers use COM+ to develop distributed applications. Administrators use Component Services to manage those applications. An administrator receives a COM+ application file from a developer and then uses Component Services to deploy that application on a server computer. Next, the administrator configures permissions for the application, as well as other settings.

As an administrator, you can deploy and administer COM+ applications in two primary ways. You can use the Component Services snap-in in Microsoft Management Console (MMC), or you can write scripts to automate deployment and administration. As an alternative to using the Component Services MMC snap-in, you can automate any of the tasks by writing code that uses administration objects that are provided through the COMAdmin Library dynamic-link library (DLL).

Component Services application types

Most Component Services administrative tasks involve deploying applications and components on the network and ensuring high performance and security for the deployed applications and components.

Applications that you administer with the Component Services snap-in fall into one of two categories: COM applications and COM+ applications.

COM applications

The idea of Component Object Model (COM) applications is not at all new. "COM" is simply the term that is used to refer to groups of COM components that were developed to work together. An example of a COM application is Microsoft Office Excel, which consists of a primary executable and accompanying application extension DLLs for the spell checker, Microsoft Visual Basic functionality, and so on.

COM+ applications

COM+ applications are groups of COM components that were developed and configured together to make use of COM+ services such as queuing, role-based security, and so on. A COM+ application is written into the component code, it is defined through the Component Services snap-in. [pic]
