What is wrong with this connection String?

set adoConn = server.CreateObject("ADODB.Connection")
set adoCmd = server.CreateObject("ADODB.Command")

strConnectionString = "PROVIDER=Microsoft.Jet.OLEDB.3.51;Persist Security Info=False;DefaultDir=C:\Program Files\Microsoft Office\Office\Samples;Driver={Microsoft Access Driver (*.mdb)};DriverId=281;FIL=MS Access"

adoConn.Open strConnectionString

I get the following Error:

ADODB.Connection error '800a0e7a'

ADO could not find the specified provider.

Can Someone Please Help.
Thanks In Advance!
