We have been running the original version of OSX -Server for about three years, I believe... it may have been closer to two years. We did one required update during that time. It was running on the same bench with an NT (later a W2K), AppleShare 6.3.3 and a Linux box. The Linux box is absolutely stable. The OSX box never crashed either. I just had a few minor problems that it lost contact to its keyboard and mouse - because we run all three servers through a KVM switch, i.e. one keyboard and one mouse for all three machines. The Windows 2K box was equally stable. AppleShare IP 6.3.3 became equally stable with the last upgrade. I have had the new OSX server in beta testing and have been using the final developer release (not quite "golden" I believe, for the last couple of weeks. This is also a UNIX based operating system, but most of the UNIX stuff is hidden from the operator. (There is a terminal access, but it is difficult to find and not needed for average server maintenance. If no streaming server and extensive interactive web pages are needed, Appleshare IP is a good choice. If a streaming server is needed, OSX would be my first choice, if complex security is required and a technician is at hand , W2k would probably be my choice, if i knew more about all of this, I would probably go for LINUX for all of the above reasons. For a Learning Center/Language Center environment, OSX-Server is a very good choice for several reasons: educational price is $499 with unlimited clients on PCs and Macs! (Compare that with Microsoft's pricing!). It is easy to set up and easy to maintain. It has a streaming server built in, it handles web pages well, and it handles file and print services for both platforms. I is much easier to set up for services to Macs and Windows machines than W2K and Linux. I would like to say more, but I am still bound by the non-disclosure rules. Otmar
