Issue/Introduction

Summary:

If IIS has a problem with isapi_redirect.dll filter, we may need to look at the isapi_redirect.log in order to investigate the problem.

In file C:\Program Files\CA\DSM\Web Console\jakarta\isapi_redirect.properties the log file is configured at following path:

log_file=C:\Program Files\CA\DSM\Web Console\logs\isapi_redirect.log

However, the isapi_redirect.log file is not present in this path.

Solution:

A process w3wp.exe (IIS Worker Process) starting under the "Network Service" account loads the file C:\Program Files\CA\DSM\Web Console\jakarta\isapi_redirect.dll.

This process should also write in the file C:\Program Files\CA\DSM\Web Console\logs\isapi_redirect.log

By default the NTFS security rights on C:\Program Files\CA\DSM\Web Console\logs allows only Read access to the group "Users".

The user "Network Service" belongs to group "Authenticated Users" which belongs to the group Users.

As w3wp.exe is started with "Network Service", it has no write rights on the directory C:\Program Files\CA\DSM\Web Console\logs.

Therefore, the file C:\Program Files\CA\DSM\Web Console\logs\isapi_redirect.log is not created.

• Add NTFS Modify rights on group "Users" for directory "C:\Program Files\CA\DSM\Web Console\logs" Or add the user "NETWORK SERVICE" with NTFS Modify rights on the directory "C:\Program Files\CA\DSM\Web Console\logs".

• Restart IIS & tomcat:

  iisreset
  caf stop tomcat
  caf start tomcat

The file C:\Program Files\CA\DSM\Web Console\logs\isapi_redirect.log should now be created.

• In order to have more detail in this file we could set the log level to trace:
  
  
  • Edit file C:\Program Files\CA\DSM\Web Console\jakarta\isapi_redirect.properties with notepad
    
    
  • Change value of log_level to trace:

    log_level=trace

    <Please see attached file for image>

    
    
    

  • Recycle IIS & Tomcat.
