Greetings again Ray: I did mention that we were 100% 10base2 here and had I had a crossover UTP cable to try, would have found the problem myself..
Your experience let you say the magic phrase: Auto-media on 3Com cards don't always work - which was the case.. Default 10baseT, I had to re-flash it with the setup Dos program.. All's now well discovering that I had been lucky before with my SMC and RealTek NIC's all auto sensing without my intervention.. APPRECIATE!! Happy Holiday...
