I've just gotten around to analyzing our log files. After banging my head with log parser and several other 'analyzer' tools I came to realize that my log files appear to be missing their header section. There are no #Software, #Version, #Date nor #Fields directives – it just starts right into the log data.
I've looked closely at the IIS logging dialog and don't see a bool there to 'enable header' or anything…
I'm using Windows Server 2008 (x64) running IIS version 7.0.6000.
Thanks.

Make sure the log file format has been set to
W3C
and notIIS
orNCSA
. In both of those instances, the log files have no header.If your log files are in W3C format, the log filenames will begin with
u_ex
by default. For IIS format the prefix isu_in
and for NCSA the prefix isu_nc
