Just to be complete, the DHCP handling that Scott descibes is only the case
when there is no dynamic dns available. In real life it turns out that most
of
the time there is no dynamic dns available, I know. But if you have it,
then
Netview on Unix will properly replace the address cards on workstations
where
they change. That is the extent of the design at this point. It needs names
to know the address has changed.
Cordially,

Thats not entirely true. Windows DHCP machines if discovered will exhibit
this behavior when they do not have forwarding turned on or even have two
interfaces. I have an enhancement request to support discovery of devices
with this behavior pending. This comment is for Unix only by the way.
If the DHCP workstation is managed, and his IP address changes, NETMON will
add an additional interface and treat the device as a router. One interface
will be down, the other will be up. Packet forwarding was turned off in all
cases of this behavior. The PMR I have opened on this has already rolled
off history, maybe someone in support (ARE YOU LISTENING PAUL!) can find
it. We discovered this because we attempted to run with all over our nodes
managed (and I do mean all, including 1500+ Windows DHCP workstations). We
kept having workstation icons promoted to routers and moved to top level
map.

By definition, any device with at least two interface cards in different
networks, which also has IP forwarding turned on, is a router. That's what
NetView is telling you. You can turn off IP forwarding on that box and it
will no longer be a router, but you will probably have to delete and
rediscover it to get the map re-drawn. Or you can leave it one and
understand that it is NetView which is correct about what is, and what is
not, a router.

Dear all,
The Netview will recognize some servers (two interface cards) as routers
but actually not. Why ? In what situation that Netview will recognize
something as routers ? for example multiple interface cards ? or any
others? How could I reset them to ordinary servers? Please help,
thanks...
