OS/2 and Netware? Those bring back some very old memories. As well as a bunch of other stuff? MAC address overload!!!! Sorry, I really intended to help. But after analyzing this sort of thing all day, by mind is kinda fuzzy now. Gotta admit, that's a lot of gear. I'm holding on to these e-mails so I can look at some of this with clearer head to see if I can help you troubleshoot.
