But your *aren't* controlling it. The loadlibrary seek priority is a set path. The user must first connect to the share, and launch the file from the share. THAT makes it part of the working directory. These are not the droids you are looking for. This particular execution mechanism still makes lpksetup run and it still launches UAC. Now what IS interesting is that, as I've previously stated, when one cancels UAC, the oci.dll is still executed - however it can only run code that the user can. Thus, if you are going to get a user to connect to a share and launch a file from that share, why make it go through all that crap (and launch UAC) when you can just have them run an EXE that does whatever you want in user mode without worrying about UAC at all. That's my main point. t _______________________________________________ Full-Disclosure - We believe in it.
