when i opened my website,i encountered this error:

Microsoft OLE DB Provider for ODBC Drivers error '80040e21'
ODBC driver does not support the requested properties¡£
/index.asp£¬line 7


but while i uploades all the same pages to an other server,it can display normally without any errors. it also passed the test on my own computer with iis5.0



it made me crazy. please give me a hand.

here is some codes:
Code:
=================conn.asp========================================
<%
StrSQL="DBQ="+server.mappath("admin/psnews.asp")+";DRIVER={Microsoft Access Driver (*.mdb)};"

set conn=server.createobject("ADODB.CONNECTION")
conn.open StrSQL
%>

=================index.asp========================================


<% Response.Expires = 0 %>

<!--#include file=conn.asp -->
<%
set rs=server.CreateObject("ADODB.RecordSet")
source="select * from BigClass"
rs.Open source,conn,1,1

set rs6=server.CreateObject("ADODB.RecordSet")   '
source6="select * from bulletin order by update2 DESC"
rs6.Open source6,conn,1,1


set rs5=server.CreateObject("ADODB.RecordSet")   
source5="select * from smallclass where bigclassid=36 order by smallclassID DESC"
rs5.Open source5,conn,1,1




 set rs7=server.CreateObject("ADODB.RecordSet")  
 source7="select top 5 * from news where smallclassid=66 order by newsid DESC"
 rs7.Open source7,conn,1,1

 set rs8=server.CreateObject("ADODB.RecordSet")  
 source8="select top 5 * from news where smallclassid=64 order by newsid DESC"
 rs8.Open source8,conn,1,1
%>
