A family of Microsoft relational database management systems designed for ease of use.
ActiveX controls must be registered on the computer using them. I've never heard of anyone registering one on a share, but maybe its possible. I think what you will have to do is copy it over to your Windows System32 folder and register it.
But if the database runs without it then you don't need it. Open the database and click through until all is clear. Then press Alt+F11 to open the code window. While in that window click on Tools>References. When the wizard opens uncheck that library.
