Question on $UsnJrnl file

Hello,

I've recently started examining the $UsnJrnl, $LogFile files for malware cases and have noticed that it only keeps about a days worth of data, before over writing. I would like to increase the default size of the $UsnJrnl files across my corporate network to keep about a week of logs.

I've tried researching an easy way to make this change maybe through some kind of scripting language, but have not been able to find anything.

I did find a website from Microsoft on how to change the size manually, but this would not be a scalable solution for a network enterprise environment.

Has anyone delt with this in the past or have any creative ideas on how I could increase the size of at least the $UsnJrnl and possibly $LogFiles.

Thank you
