I think, that you run your servers only with frames ethernet_ii (load ne2000 port=300 int=10 frame=ethernet_ii etc.). But your clients runs with origin 'net.cfg', where are usually options like: link driver <<de0>> frame ethernet_ii frame ethernte_802.2 frame ethrenet_802.3 ... In this case the default frame type is usually 802.2 and according README in /sys/i386/ipxnet (?) ipx protocol knows only ii. If I am true, try configure 'net.cfg' on some client (e.g. delete lines with 802.x or snap) and give to know. I don't know, what exactly means 'promiscuous mode'. I guess, that such interface some strange way sends ALL frames types to (IPXrouted) and, maybe, IPXrouted knows 802.2 etc. It was explained behaviour your LAN. (Option -s for IPXrouted isn't needed. One knows, that if the pc has two or more interfaces, pc is router and program will be propagate routing table.) Can you send me list from 'netstat -r', 'netstat -i'? I have exactly the same problem + problem, that I installed 2.2.1R in sunday and from this time my brave server 3 times CRASHED. My favourite 2.1.0R never crashed. JPB (Josef P.
