Web Verifier HTTP Error 500.21 "Handler "PageHandlerFactory-Integrated-4.0" has a bad module "ManagedPipelineHandler" in its module list" (Doc ID 2998327.1)

Last updated on JANUARY 17, 2024

Applies to:

Oracle WebCenter Forms Recognition - Version to [Release 12c]
Information in this document applies to any platform.


A WebCenter Forms Recognition system was upgraded from Windows 2012 to Windows 2016.  After upgrade the following error occurs when opening Web Verifier:

HTTP Error 500.21 - Internal Server Error
Handler "PageHandlerFactory-Integrated-4.0" has a bad module "ManagedPipelineHandler" in its module list

Most likely causes:
 - Managed handler is used; however, ASP.NET is not installed or is not installed completely.
 - There is a typographical error in the configuration for the handler module list.
 - During application initialization, either the application initialization feature has set skipManagedModules to true, or a rewrite rule is setting a URL that maps to a managed handler and is also setting SKIP_MANAGED_MODULES=1.

Things you can try:
 - Install ASP.NET if you are using managed hanlder.
 - Ensure that the handler module's name is specified correctly. Module names are case-sensitive and use the format moudles="StaticFileModule,DefaultDocumentModule,DirectoryListingModule".
 - Ensure that any application initialization rewrite rules set SKIP_MANAGED_MODULE=0 when setting a URL that maps to a managed handler (such as .aspx, for example.)
 - As an alternative, ensure that application initialization rewrite rules map the request to an unmanaged handler (for example, to an .htm file, which is mapped to the StaticFileHandler.)
