Best pratice to troubleshoot cron.php error

[Gilneas]

Hey guys,

I got some trouble with the cron job. We are using sugar Version 6.1.2. When I try to run the cron from console I get the following error:

Bad data passed in; <a href= "http://<webservername>/sugar">Return to home</a>
Fatal error: Class 'LogicHook' not found in <Drive>:\<path>\sugar\include\utils.php on line 2602

There are no additional information in the sugarcrm.log file. I had a look at the utils.php but I could not found anything telling me 'hey, I'm a wrong code line'.
The line 2602 is just:

     LogicHook::initialize(); 
  

Facts about the system:
Windows system with xampp installation providing sugarCE 6.1.2 . Nearly standard installation, most customizations made in language files or by additional modules.

Can someone tell me how to figure out what goes wrong with my corn run, please?
How can i implement this class "LogicHook"?

Found this kb article
http://www.sugarcrm.com/kb/tag/cron-jobs/

I compared my batch file with the one from kb article. The reason for my cron job to fail was that the working directory was not changed to the dir which inherits cron.php.

The cron job needs a correct working directory.
