ADM 331 Administrative Scripting for IIS 6.0 Using WMI

• Alexis Eller Program Manager

• Internet Information Services (IIS)

Agenda

• Overview of the Windows Script Host

• Manageability improvements in IIS 6.0

• Overview of Windows Management Instrumentation

• IIS 6.0 WMI Provider

• Practical examples

• Special notes regarding JScript & WMI

Overview of the Windows Script Host

• Automation

• Provisioning

• Custom tools

• Rich object model

• Access to automation COM objects

Manageability Improvements in IIS 6.0

• Metabase stored in XML

• Editable while the server is running
• Automatic versioning and history

• Password protected backups

• Import & Export

• Command line administration

• Remote administration

• IIS WMI Provider

Command line Administration for IIS 6.0

• Use the IIS WMI provider

• Supplied VBScript scripts manage

• Common web and FTP tasks
• Use from command line, batch jobs
• Serve as IIS WMI scripting examples

• ADSI provider still supported

• Create scripts using the IIS providers

In the System32 Directory

• Web: iisweb.vbs, iisvdir.vbs

• FTP: iisftp.vbs, iisftpdr.vbs

• Metabase backup/restore: iisback.vbs

• Import/export: iiscnfg.vbs

• Application extensions, dependencies, files: iisext.vbs

• Mapping between worker process and application pool: iisapp.vbs

WMI Overview

• Introduced in Windows 2000

• Uses the object oriented model

• Universal way to access machine information

• Consistent, unified view of managed objects

• Supports SQL-like queries (WQL)

IIS 6.0 WMI Provider

• Extends WMI schema to include IIS classes

• Represents the IIS metabase
• Equivalent ADSI classes and more…

• Class/Instance provider

• Method provider

• IIS Namespace: root\MicrosoftIISv2

IIS 6.0 WMI Provider

• Each IIS object available through WMI

• IIsWebServer, IIsFtpServer, etc.
• Similar to ADSI IIS classes

• Separates read-only from read-write properties

• IIsWebServer vs. IIsWebServerSetting

• Association classes represent relationships

IIS 6.0 WMI Provider

• New classes to represent structured data

• ServerBinding, SecureBinding
• ScriptMap, MimeMap
• ApplicationDependency, WebSvcExtRestrictionList
• HttpError, HttpCustomHeader, CustomErrorDescription

Going Deeper

• Monitoring

• Using notification queries

• Security Audit

• Look for properties set with suspicious values

• Bulk operations

• Multiple operations

Scripting WMI Using JScript

• Method Output Parameters

• VBScript: Methods can be called directly
• JScript: Methods are called with the SWbemMethod, InParam and OutParam objects.

• WMI Arrays

• VBScript: handle as usual
• JScript: use the toArray() function to convert the WMI safearray to an array recognized by the JScript engine

Methods with OutParameters

Handling WMI Arrays in JScript

Call To Action

• Consider Scripting

• Leverage IIS WMI provider advantages

• Unified object model
• Querying capabilities
• Monitoring capabilities

• Review IIS 6.0 command line scripts

• Use them
• Learn from them
