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...
