ASP Object Reuired error.

I'm getting this error:

Microsoft VBScript runtime error '800a01a8'

Object required: ''

/Polling/Pollcn.asp, line 6

And I don't know what the problem is. The file is is referring to is included in a few files, and here is the code:

<%
Dim cnPoll,rsPoll,sqlPoll
cnPoll=Server.CreateObject("ADODB.CONNECTION")
cnPoll.provider ="Microsoft.Jet.OLEDB.4.0" \\this is line 6
cnPoll.Open("d:\Intranet\Polling\db\poll.mdb")
%>

Any ideas? Thanks.
