I have new installs of Autodesk Map 3D 2007 with SP1, and Autodesk Civil 3D 2007. We also run ArcSDE 9.1 with SQL Server 2000. I have incorporated the three *91.dll's needed in the FDO/bin folders and still can't connect. I have been communicating with Autodesk through my Subscription and still don't have an answer. Anyone have a solution?
