The OS of 3.12 is very very reliable. It's right before NDS came out. My point is, that if it "fails" it's because the Network Admin doesn't know how to build RAID correctly. 4 Simple commands, and I'm in, so long as the NIC came with a Netware driver. Sorry to say, Netware 3.12 does not need upgrades, therefore increasing stability. Certified in Netware and MS. I'll take a 3.12 over a top of the line MS anyday.
