problem save ntuser

[gyzmau]

Hello,

I've got a problem : I would like to save ntuser.dat when
a user logs off and replace it when a user logs in. I have
made a gina stub for that. But when I try to access
ntuser.dat, fopen returns an error. The error is
ntuser.dat is already used by another process.

Thus I would like to know how to copy this file to another
directory without bringing an error.

Thanks for your answer.
