We have the same exact issue here. I turned on the duplicate IP address
notification and have it write out to a log file whenever a dup IP trap
comes in and I was amazed at how many servers out there are using "private"
networks and how many of them are using 192.168.x.x for the address scheme.
It is hard to get teams to understand that these interfaces can been seen
with NetView. People process are hard to change.

I am assuming the issue is you have is that SNMP discovery finds the second
non-pingable interface. What is probably happening is you have more than one
server with the 192 address (based on my experience it is 192.168.254.253
-seems to pop up a lot). You unmanage the interface on one box and when a
second box is discovered also with the 192,168 interface it deletes the
first one. The config polls suddenly find it again and delete it from the
second box and add it to hte first box again - in a managed state not
unmanaged.
I would recommend two things - first use SNMP polling not ping polling. This
way, the status of the second interface can be obtained. Second, force your
server administrators to put a different address on each of servers that
have one of these interfaces. I am struggling with the same thing here with
our Dell servers.

Win2k/Netview 7.1.3. FP1 / SQL2000,
Hi list,
Maybe someone can shed some light for me. We have 3 Microsoft clusters with
several nic cards. One nic in each server is configured with an ip that are
not pingable (192.168.X.X) for the cluster heartbeat. Is there a way to
prevent Netview from discovering these interfaces? I have them in the
exclude list of the seed file and I tried to unmanage them, but somehow
Netview continues to manage these interfaces on its own.
Has anyone come accross this problem before?
Also, is there any consultant on this list located in Miami, FL please email
me directly. (Sorry for posting this here.)
