Final update, hopefully.. As of this moment, IT'S WORKING! The silver bullet in this situation was some option in SQL Server called "Allow inprocess". Not sure what this does exactly, but this option (in Server Objects | Linked Servers | Providers | IBM.UniOLEDB) has to be checked for SQL Server to play nicely with the UniOLEDB driver on this one system. No idea why this system needs to be configured differently from any others... any ideas?
My deepest gratitude for all of the insight, information, and opinion helping me through this issue. If any of you ever get nearby, margaritas on me! -K _______________________________________________ U2-Users mailing list U2-Users@listserver.u2ug.org http://listserver.u2ug.org/mailman/listinfo/u2-users
