Killing a process running on a web app

I have a web application which runs against a MSACCESS 2000 database.
Apparently whenever a web connection runs a query and exits abnormally maybe due to lost of connection or webuser termination,the ldb file remains and prevents any other web users from accessing the database.I can only kill the process by restarting the machine.Does anyone know of a way of killing this process which is linked to that ldb without restarting the server?
