Configuring the Microsoft Internet Information Services 8.5 Web Server on a Windows Server 2012 R2 System

The Tomcat redirector plug-in DLL, isapi_redirect.dll, does not work under 64-bit mode on Windows 2012 R2 with IIS 8.5. To successfully configure IIS 8.5 on a Windows 2012 R2 system, you must configure the plug-in to work in 32-bit mode.
