Permissions problem with ADO.Net and Access

I am receiving this error when trying to connect to an Access database through OleDB in an ASP.Net application...

The Microsoft Jet database engine cannot open the file 'c:\inetpub\wwwroot\OrderRequest\OrderRequest.mdb'. It is already opened exclusively by another user, or you need permission to view its data.

Here is the code I use...

Private Function GetSalesReps() As Boolean

Dim strConnection As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & Server.MapPath("/OrderRequest/OrderRequest.mdb")
Dim strSQL As String = "SELECT SalesRep FROM SalesReps"
Dim objConnection As New OleDb.OleDbConnection(strConnection)
Dim objCommand As New OleDb.OleDbCommand(strSQL, objConnection)


Try
objConnection.Open()
objConnection = New OleDb.OleDbConnection(strConnection)
objCommand = New OleDb.OleDbCommand(strSQL, objConnection)



drpSalesRep.DataSource = objCommand.ExecuteReader(CommandBehavior.CloseConnection)
drpSalesRep.DataBind()

Catch adoException As Exception
lblException.Text = adoException.Message & adoException.Source

Finally
objCommand = Nothing
objConnection = Nothing
End Try


End Function
