I’m having the same problem as JM and SWAP even after trying all the above (modiis in root and web servers, regedit, stop/start iis, reboot, reinstall).
Seems like an ISAPI filter, port contention or access permissioning thing.
Is anyone out there using Tamino with IIS4 and NT6a who couldn’t connect to a database? If you had the same problem, how did you overcome it?
Hopeful.
