Retrieving COM class Factory failed: 8007007f

[jimmyfo]

Hi, I recently wrote an ASP.Net web application in VS2005 and published
(using VS2005 Publish feature) it to a relatively clean machine with
ASP.Net 2.0 and MDAC 2.8 installed on it. However, when I try to create
my SQL connection in the code-behind, I get the following error. I
tried to register the DLL using regsvr32 but that errored out saying,
"dllregisterser ver entry point was not found". Any ideas?

Retrieving the COM class factory for component with CLSID
