I'm being troubled by this most peculiar problem. In an embedded environment, the PC (running XP Embedded) sometimes falls into a complete hangup (i.e. XP doesn't respond to anything). It is related to a hangup of the network; the PC hardware involved seems to do something on its network connection that causes the switch (brand: SMC, 24 ports) to block all traffic to/from the other participants on the network. As soon as I disconnect the cable from the hanging PC the whole networks OK again.
I wonder, which phenomenon on a single Ethernet connection could cause that a complete network is locked out?
(the vendor already has had his own internal network locked out in an attempt to reproduce the issue, so he's sure the problem exists)
