[otrs] Cron jobs in windows

I want to download pop3 mail every 5 minutes instead of 10. Looking at the manual, the chron job instructions at http://doc.otrs.org/2.1/en/html/x1215.html#email-receiving-pop3 http://doc.otrs.org/2.1/en/html/x325.html#cronjobs seem to be linux specific, we're using WindowsServer2003. Is it as simple as editing var\cron\postmaster_pop3.dist to read */5 * * * * $HOME/bin/PostMasterPOP3.pl >> /dev/null instead of */10 * * * * $HOME/bin/PostMasterPOP3.pl >> /dev/null ? Is a restart of OTRS needed to initialize it? Or do I need to set up a recurring job on the windows system itself? Keith
