Issue/Introduction

DSM Web Admin Console returns error :
 
HTTP Error 500.0 - Internal Server Error
Calling LoadLibraryEx on ISAPI filter "C:\Program Files (x86)\CA\DSM\Web Console\jakarta\isapi_redirect.dll" failed

Most likely causes:

• IIS received the request; however, an internal error occurred during the processing of the request. The root cause of this error depends on which module handles the request and what was happening in the worker process when this error occurred.
• IIS was not able to access the web.config file for the Web site or application. This can occur if the NTFS permissions are set incorrectly.
• IIS was not able to process configuration for the Web site or application.
• The authenticated user does not have permission to use this DLL.
• The request is mapped to a managed handler but the .NET Extensibility Feature is not installed.

  

 

Environment

CA Client Automation - All supported versions.

Cause

This problem could occur if there are some permissions problems on some ITCM directories.
By default IIS application ITCM_Application_Pool is executed with identity ApplicationPoolIdentity.
Some ITCM directories should have NTFS Read/Execute permissions for local group Users

Resolution

- Give NTFS Read/Execute permissions for local Users Group on following directories :
 

C:\Program Files (x86)\CA\DSM\Web Console
C:\Program Files (x86)\CA\DSM\webservices
C:\Program Files (x86)\CA\DSM\Bin
C:\Program Files (x86)\CA\SC\CBB
C:\Program Files (x86)\CA\SC\CAM\bin

 

- Restart tomcat and IIS in a command prompt :

caf stop tomcat
iisreset
caf start tomcat
