Folks, Just a little of experience here on a similar issue. We have been having the same issue at a couple of our customers and they always just rebooted their workstations and the problem went away. Upon further investigation we found that this only happened on Windows 95 not NT machines. Looking into the routing tables we found that an extra default gateway was popping up due to another device on their network sending ICMP redirects. Manually deleting the gateway fixed the problem. Sometmes the problem was intermittient as described below and it would fix itself. The solution was to turn off ICMP broadcasts from the other device. The access device we are using is an Ascend Pipeline 50. Jeff Binkley ASA Network Computing U>On Tue, 23 Nov 1999, Scot Desort wrote: U>> You do not need to disconnect. Data resumes all by itself.
