I came across a very similar situation to your's a while ago. After much confusion with very odd intermittent faults it transpired that the poorly put together Ethernet wiring would happily carry 10MHz signals, but not 100MHz. Sometimes the net worked ok as a 10MHz net, at others it failed as a 100MHz. We were confused for quite a while. After rewireing it properly, it worked perfectly. The point of the story is that it might be worth your while putting an old 10MHz card in one of the machines to force your net to run at 10MHz. If it works at the lower frequency, then that more or less proves that you have problems with noise on the cable run. Also make very sure that the gold plated connectors are clean. Old tooth brush for the plugs and pipe-cleaners for the spring loaded wires in the sockets. Also I have come across the wires in the sockets not offering sufficient pressure to the plug. A _gentle_ bend with a fine crochet-hook, or what have you, works wonders -- Sincerely etc. Christopher Sawtell NB. This PC runs Linux.
