[nv-l] NetView Multicast

["Bursik, Scott {PBSG}" <Scott.Bursik@pbsg.com>]

In an effort to troubleshoot Authentication Trap Failure errors I have
started sniffing one of the machines that is sending these events. I noticed
a LOT of traps coming in at one time on my NetView box from that machine and
the below sample is the cause of the Auth. Failure traps. I searched the
archives and see one thread talking about this condition but there was no
resolution and the address showing in packet is the same as that thread.

Here is the thread I read:

http://lists.skills-1st.co.uk/mharc/html/nv-l/1999-08/msg00259.html

Any ideas?
