    • If you are using Windows Vista or Windows 7:

      • On the taskbar, click Start, and then click Control Panel.
      • Double-click Administrative Tools, and then double-click Internet Information Services (IIS) Manager.

  2. In the Connections pane, click the server connection to which you want to add the native module.

  3. On the server Home page, double-click Modules.
    Screenshot that shows the Modules is highlighted.

  4. In the Actions pane, click Configure Native Modules...

  5. In the Configure Native Modules dialog box, click Register...

  8. In the Configure Native Modules dialog box, select the option for the native module that you just registered, click OK, and then click OK again. This enables the native module to run and makes it available to sites and applications on your Web server.

    Note

    If you do not want to enable the native module to run, clear the option for the native module, and then click OK.

  9. Optionally, you can lock the native module if you do not want it to be overridden at lower levels in the configuration system. On the Modules page, select the module, and then click Lock in the Actions pane.

Configuration

Each <add> element in the <globalModules> collection must contain a name attribute that identifies the module, and an image attribute that points to the DLL that implements the module.

Attributes

Attribute Description
image Required string attribute.

Specifies the physical path of the .dll file for the global module. The attribute value will be expanded when environment variables, such as %windir%, are used.
name Required string attribute.

Specifies the name of the global module.
preCondition Optional string attribute.

Specifies conditions under which the global module will run.

The preCondition attribute can have one or more of the following possible values. If you specify more than one value, separate the values with a comma (,).
Value Description
bitness32 Specify the bitness32 value when the global module is a 32-bit .dll file, and IIS should load the global module only for worker processes that run in WOW64 mode (32-bit simulation) on a 64-bit operating system.
bitness64 Specify the bitness64 value when the global module is a 64-bit .dll file, and IIS should load the global module only for worker processes that run in 64-bit mode.
integratedMode Specify the integratedMode value when the global module should use the integrated request-processing pipeline to process requests for managed content.
ISAPIMode Specify the ISAPIMode value when the global module should use the ASP.NET ISAPI extension, Aspnet_isapi.dll, to process requests for managed content.
runtimeVersionv1.1 Specify the runtimeVersionv1.1 value when the global module should load only for application pools that are configured to use .NET Framework version 1.1.
runtimeVersionv2.0 Specify the runtimeVersionv2.0 value when the global module should load only for application pools that are configured to use .NET Framework version 2.0.

Child Elements

None.

Configuration Sample

The following example shows an IIS 7 <globalModules> section that contains entries for all modules included in the minimal installation of the Web server. It also includes an entry for the BasicAuthenticationModule and another for the ImageCopyrightModule third-party module.

<globalModules>
   <add name="UriCacheModule"
      image="%windir%\System32\inetsrv\cachuri.dll" />
   <add name="FileCacheModule"
      image="%windir%\System32\inetsrv\cachfile.dll" />
   <add name="TokenCacheModule"
      image="%windir%\System32\inetsrv\cachtokn.dll" />
   <add name="HttpCacheModule"
      image="%windir%\System32\inetsrv\cachhttp.dll" />
   <add name="StaticCompressionModule"
      image="%windir%\System32\inetsrv\compstat.dll" />
   <add name="DefaultDocumentModule"
      image="%windir%\System32\inetsrv\defdoc.dll" />
   <add name="DirectoryListingModule"
      image="%windir%\System32\inetsrv\dirlist.dll" />
   <add name="ProtocolSupportModule"
      image="%windir%\System32\inetsrv\protsup.dll" />
   <add name="StaticFileModule"
      image="%windir%\System32\inetsrv\static.dll" />
   <add name="AnonymousAuthenticationModule"
      image="%windir%\System32\inetsrv\authanon.dll" />
   <add name="RequestFilteringModule"
      image="%windir%\System32\inetsrv\modrqflt.dll" />
   <add name="CustomErrorModule"
      image="%windir%\System32\inetsrv\custerr.dll" />
   <add name="HttpLoggingModule"
      image="%windir%\System32\inetsrv\loghttp.dll" />
   <add name="RequestMonitorModule"
      image="%windir%\System32\inetsrv\iisreqs.dll" />
   <add name="BasicAuthenticationModule"
      image="%windir%\System32\inetsrv\authbas.dll" />
   <add name="ImageCopyrightModule"
      image="%windir%\System32\inetsrv\ImageCopyrightModule.dll" />
</globalModules>

Sample Code

The following examples install a native module named ImageCopyrightModule on IIS 7 and automatically enable it on the entire server.

AppCmd.exe

appcmd.exe install module /name:ImageCopyrightModule /image:%windir%\system32\inetsrv\imageCopyrightModule.dll

You can also use the following syntax:

appcmd.exe set config -section:system.webServer/globalModules /+"[name='ImageCopyrightModule',image='%windir%\system32\inetsrv\imageCopyrightModule.dll']" /commit:apphost

Note

You must be sure to set the commit parameter to apphost when you use AppCmd.exe to configure these settings. This commits the configuration settings to the appropriate location section in the ApplicationHost.config file.
