file system minifilter and unc path

Hi,

I have a file system minifilter driver (developed by someone else). It monitors file read request generated by programs (I don’t know exactly everything, although I have the source code). I attach this driver to a volume. When a file is opened in a program (e.g. an image file in mspaint), this minifilter driver intercepts this request and calls another application after checking some criteria.

Everything works perfectly when I open the file using absolute file paths (like D:\folder1\folder2\file1.bmp). I have also shared D:\folder1 as \\mypc\folder1. On the same computer, when I open the same file using unc path (like \\mypc\folder1\folder2\file1.bmp), the minifilter driver does not intercept it.

Please can someone provide some solution so that minifilter driver also work with unc pathnames.

I use the following commands to load/attach/unload driver.
- fltmc load my_driver
- fltmc attach my_driver volume
- fltmc unload my_driver

Thanks
