Couldn't open File. Error "Exclusive mode"

[Carmen]

Hy,

I made an application in Visual Basic Net that managed a
share database (access 2000) using ADO. But, I have this
problem: if a second user wants to connect to the database
this message is displayed "The Microsoft Jet database
engine cannot open the
file '\\MyComputer\Base\Employees.mdb'. It is already
opened exclusively by another user, or you need permission
to view its data".

In my mdw file nobody has rights to open the database in
exclusive mode and in the code, I use the
mode "adShareDenyNone" to open the database. This problem
occurs mostly in computers whith Win98.

does anyone know how can I resolve it?

Thanks a lot,
Carmen
