Sounds like a duplicate IP address problem or a problem with a device's ARP
cache. Did you try giving all the layer 3 devices new node addresses on the
original subnet numbers? Or just unplug each device, and see if you can
still ping it, indicating a duplicate address. Sniffer will point out
duplicate addresses as well.

Subject: ip routing
Hello,
Last week we have encountered a problme with slow e-mail access on one
of the subnets on our network. We've done extensive troubleshooting.
We've repalced the router, token ring switch, NIC on the e-mail server.
Then we found out that if we change the ip address of that lan
everything works fine. So the problem is either with an IP address or
routing that particular ip address. Another thing is that from that
subnet we were not able to telnet to some of the Unix machines that we
have on the same subnet as e-mail server. I do not know if it is related
or not.
Here is the topology.
TR-LAN---3600-----5505 with RSM-----3548---e-mai ser.
Thanks
