Thank you for providing some information. But I do not understand what types of objects require read permission in order to successfully open with SYNCHRONIZE access. On Windows XP Professional SP2, using CreateFile(...,GENERIC_WRITE | SYNCHRONIZE, ...) to open an ordinary file on a local drive that has write-only permissions does not seem to be a problem. I am primarily interested in the "buggy behavior" that a user would experience if CreateFile() was used instead of NtCreateFile().
