Not true at all. In the late '90s, I used to run HP OpenMail to Schedule+ and, later, Outlook 97/98/2000 clients using it's MAPI SP. Turn of the millenium, I used to use Bynari InsightConnector for Outlook 98/2000 clients using its more stable connection than a MAPI SP. And there are countless other examples. But no, you can't just drop in one vendor's solution for another without some changes. I don't know any solutions in the world that work that way. But I can tell you it's far, far less painful to upgrade to a Samba server (and a _real_ enterprise backend) from a NT4.0 domain than to ADS. -- Bryan J.
