I am trying to access a MS Access database which is on a remote server and with my DSN less connection I get the following error , can you please tell me what could be the reason behind.

My code is
%@LANGUAGE="VBSCRIPT"%>
<!--#INCLUDE virtual="/common/pricelist.asp"-->
<%
Dim ConnectionString
dim oConn

ConnectionString = "DRIVER={Microsoft Access Driver (*.mdb)};" &_
"DBQ=\\Server167\BusOps\Maint_ Ren_ Web_ Page_ Upload_DB.mdb;DefaultDir=;UID=;PWD=;"

Dim objRS
Set objRS = Server.CreateObject("ADODB.Recordset")
objRS.Open "Select * from [Maintenance Report] where country = 'AD'", ConnectionString

%>

and the error that I get is

Microsoft OLE DB Provider for ODBC Drivers error '80004005'

[Microsoft][ODBC Microsoft Access Driver] The Microsoft Jet database engine cannot open the file '(unknown)'. It is already opened exclusively by another user, or you need permission to view its data.
