I'm not sure what you're asking here, Schoa: you want to kill the file but you don't want to use kill???
I wonder if the best solution might be to run this report from a script in Windows Scheduler, which would delete the file and then call Access with an /x macroname runtime command switch to run the report.
I have never heard of "taskkill" and I have no idea what difference Server 2008 would make; you might want to ask this in a Server forum.
