I don't know of any specific ill repute associated with DEMPR's. Our last
major net disease was one bad thin wire ethernet card that was slobbering
over everybody else's messages, and *not* being isolated by our thin-wire
device (cabletron DEMPR equivalent).
Check that your ethernet follows the conservative side of all the ethernet
configuration rules, then start unplugging things till you isolate the bad
branch/unit... If this isn't a breakdown, but an on-going problem you've
just recognized, check the cabling and little things like heart-beat presence
corresponding to type of device.
pithy quote of the day:
"...the worst problem with thin-wire is the existance of arcnet cables"...
