I wonder if the way you specified the negative entries is valid. To exclude
both and adresses from the discovery, I think
you must specify this : ! 

Moreover on Netview 5.1.2 (NT), it exists a registry key that netmon uses to
allow/avoid duplicate address :
(HKEY_LOCAL_MACHINE\Software\Tivoli\TME 10 Netview\AllowDupIpNames) but I do
not know if this registry key still exist on Netview 6.0.1(NT)

The network I work on has been customized with duplicate addresses of and  These addresses were assigned to

okay to do this because 192.168.10 is considered a "private network" and
is not routed over the network.  The platforms with these addresses contain
additional network cards which are unique and which are what I really
want to monitor.

I have tried via a seedfile to get netmon to ignore these addresses

I see in the NetView Diagnsis Guide the  documented solution is to "Correct
problem in your network".  However, it would be more desirable if I could
just get NetView to ignore the duplicate addresses.  Does anyone know
another way to get NetView to ignore the duplicate addresses but still
monitor the
rest of the platforms?
