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,
"dllregisterserver entry point was not found". Any ideas?

Retrieving the COM class factory for component with CLSID
{2206CDB2-19C1-11D1-89E0-00C04FD7A829} failed due to the following
error: 8007007f.
