Hi all,
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)
Any clues?
