I just found on our Front End Servers where there are no trace logs under 12\LOGS. The log files are there but without any message inside.

‘This gives you the current settings
stsadm.exe -o listlogginglevels

Run this before doing any changes on a machine. It’s always good to know the original settings before making changes.

‘This set the logging to Verbose / Error.
stsadm -o setlogginglevel -tracelevel Verbose -windowslogginglevel Error

“C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\12\bin\stsadm” -o setlogginglevel -tracelevel Verbose -windowslogginglevel Error
