I was a systems engineer and also taught NetWare admin classes. I also worked with Novell to update their training material.<p>I remember the first release of NetWare 386 very well; it was a breeze to install, but the early version had a bug and if you unplugged the 10Base2 coax from the server it would crash. Apparently, the routine to display a warning message on the console had an issue. Novell issued a patch NLM.<p>I had one site that experienced random crashes, but it was not the aforementioned bug. Long story short: After about two months of sleuthing, working with Novell and Compaq, camping on site and driving to/from the office to site (about 2hr each way), I found that it was a mains spike caused by a dishwasher right up against the server room wall in the next room.<p>The fix was to move the Compaq server, which was actually a large desktop model, on its table to the opposite end of the server room.
