Hi PT,

it seems you are describing a loop. would you check also:

a) ping TTL value

b) STP compatibility and working order

c) mistmatching port speeds (make sure everything is working on  100+Mbps Full Duplex

d) you can perform a traffic analysis with Wireshark or similar and to realise whether malformed packets are formed on this 2950

the point d is the last i am suggesting you to check. by the version you should use, i would say that the 12.2(58) is the one you want running on those machines.

hope this helps
