[c-nsp] [Forum] show arp hardware type INCOMPLETE

[Luis Augusto Tiani da Silva *Luist*]

I didn't make myself clear..... We have a little and simple network, with a
server (NT) and some workstations. There no face with internet. Those
address in the arp table of our router doesn't exist in our network, there
is no workstation configured with those addresses. I've been seing some docs
in the internet and I thought it might be a worm, CODE RED, but we don't
have IIS in this network, and when those IP's start to appear in the arp
table of the router, the most workstations, even the server, get the network
connection lost and get it back, and get lost.... until we restart the
machines or unplug and plug the cables from hub's/switches....
 
better now? Have you ever seen this?
Tks!

Where are these servers plugged into.  ARP is incomplete because the servers
are unreachable. There is nothing wrong with seeing incomplete arp, you need
to trace where the end devices plug into.
