Hi,
Thanks, that should work.

The problem is that we are interfacing to a government dept using PKI software supplied by them (Not very well written) which creates temp files in it's own %PROGRAMFILES% directory, and if the rights change, the software does not work, no errors.

I just need to check that the correct rights are set in their software directory prior to transmission, and if not set the required rights.

>>What I am looking for is the best way (via code) of sensing the change and resetting to the required rights, any ideas.
