You state the obvious with little regard for quality of information. I'd like to address the "attractiveness" statement first. It has little to do with "attractiveness" or lack there of to the platform. Oh, maybe you're right. Because MS has no clue how to develop a secure platform, it becomes a bowl of honey to the hackerbees. In fact, I suspect you realize that and are working to foster the idea that GroupWise is not worth hacking, rather than stating the obvious, which is my 17 year oldson could hack most MS products. Ask me how to read your email without you ever knowing it happened.
Also CIO's love to double their hardware costs, and spend more for all the extra administrators, maintanence costs, and hidden license fees.
Now let me address your other comment about "pure NT network". The reason GroupWise runs on Netware is obvious, but it runs equally well on NT, Win2K (also NT in disguise), and Unix. Because no company of any size can survive on a single platform if it has a clue what 'best of breed' means, chances are there are multiple platforms scattered throughout the enterprize. Let me help you understand. Best of breed means you choose the best platform for the job. Sometimes it is MS, sometimes Sun, sometimes Netware..... MS Exchange runs best on MS NT because that is ALL it runs on. And I won't even get into the inActive Directory arguement but let me say this, if you are working in anything larger than a doctor's office, I wish you luck implementing a solid AD solution. By the way, what other platforms does AD run on?
Thanks for the opening. It's always fun to discuss GroupWise and Exchange. GET REAL instead.
