mdaccess b - Microsoft JET Database Engine error '80004005'

Question

Overnight (after a windows update) my MDB files no longer open via IIS - ASP) with the message:

Microsoft JET Database Engine error '80004005' - non-specific error.

Connection stopped working for any MDB file.

Set oConn = Server.Createobject("ADODB.Connection") 'oconn.open "Provider=Microsoft.Jet.OLEDB. 4.0;" & "Data Source=" & Server.Mappath("/prgrm/secure.mdb") & ";"

I reinstalled the engine. I reconfigured the IIS to run 32-bit applications. I checked folder and MDB file permissions.
