WMS Active Script Event Handler - general properties

The WMS Active Script Event Handler plug-in enables you to attach a custom script that you can use to provide feedback about events on your Windows Media server. You can write the script in any scripting language that supports the Microsoft ActiveX scripting interfaces; for example, Microsoft JScript, Microsoft Visual Basic Scripting Edition (VBScript), Perl, PScript, and Python. You can configure the following options for this plug-in.

Item	Description
File name of script to run	Type the name of the script file that you want to run. In the Windows Media Services snap-in, you can also click Browse to locate the file.
Debugging information	Settings in this area determine whether or not you will use a debugger with your script file.
Enable script debugging	Select this option to attach the Microsoft Script Debugger to your script file. If an error is encountered while running the script, the debugger stops the script, traps the error, and presents the error in a dialog box to enable you to troubleshoot the problem.
Last script error information	Settings in this area provide information about the last error encountered when the specified script was run.
Line number	Displays the line number in the script file where the error was encountered.
Character Column	Displays the character number in the line where the error was encountered.
Most recent error message	Displays the error code that the scripting engine encountered.

Note Image Notes

To enable script debugging, a script debugger must be installed on your server. You can download the Microsoft Script Debugger from the Microsoft Scripting Technologies page on the Microsoft Web site.
The Microsoft Script Debugger does not work with the Network Service account. In order to use the Microsoft Script Debugger with Windows Media Services, you must configure Windows Media Services to use the Local System account. When using the Local System account, Windows Media Services will have limited access to network resources that require authentication when those resources are referenced by using IP addresses. Remember to set Windows Media Services to use the Network Service account when debugging is complete to resume normal operation.
The proper script engine must be installed for the debugger to work correctly. The VBScript and JScript engines are installed by default with the Windows operating system. If you use another scripting language, be sure to install the proper script engine.
Custom or third-party plug-ins should be located in a protected directory to prevent tampering. The protected directory can be any directory that has been set to deny write permissions to unauthorized users. For more information about restricting directory access, see Windows Help and Support.
The WMS Active Script Event Handler plug-in is available only if Windows Media Services 9 Series is running on the following editions of the operating system: Windows Server 2003, Enterprise Edition and Windows Server 2003, Datacenter Edition. If you are running Windows Server 2003, Standard Edition, this feature is not supported.
