The Tiny PXE Server logging function was removed in build 188.8.131.52 (Feb 12, 2017 - 19:29). A syslog daemon (syslogd.exe) is now included in the Tiny PXE Server download.
Add the following to C:\pxesrv\config.ini -
Start the syslog daemon - Tiny PXE Server will now log to C:\pxesrv\log.txt - review this file as required for troubleshooting, etc.
