Bootwiz logs are created on the SMP during creation/recreation of Automation Folders.   Bootwiz logs are also created on Site Server(s) that have the NBS service installed and on which a preconfiguration has been created.

By default, the Bootwiz logs follow the settings set in the registry at [HKEY_LOCAL_MACHINE\SOFTWARE\Altiris\BDC\logfile].

[HKEY_LOCAL_MACHINE\SOFTWARE\Altiris\BDC\logfile]

"file"="*"
"screen"="false"
"severity"="d"
"append"="a"

The values can be modified to meet individual needs.  E.g File="*" which places the log file in the same folder as Bootwiz, can be change to have the file go to a specific directory. (File=c:\fred)
