Does the file exist?  What mode is the create?  In the logs I've viewed
as a part of 130548 the create mode is "open" which means only open the
file if it already exists.  If it doesn't already exist, the error will
correctly be NAME NOT FOUND.

FSCTL_LMR_QUERY_DEBUG_INFO is a Lan Manager specific FSCTL.  It is not
supported on any other file system.  Invalid Device Request is the
correct response.

> IRP_MJ_DIRECTORY_CONTROL       NO SUCH FILE

For what path?  What is the query mask that is being searched for?  Do
directory entries that match the mask exist?  In the logs I've examined
the file name being searched for is the same file name that was given to
the IRP_MJ_CREATE.  The file doesn't exist and therefore NO SUCH FILE is
the correct response.

Since nothing is actually creating the file and the something that
should make an attempt to do so is Acrobat, I'm suspicious.  I'm not
pointing a finger since Acrobat clearly saves the file elsewhere but I
don't have enough data.
