Jens, My guess would be a name resolution problem. See if you have forward
and reverse name resolution. You may want to see if the device is in the
local host table or do a loadhosts command. You might also want to do a
traceroute to see if there is some kind of routing problem.

Subject: NetView cannot discover a node

>Also I can used the MIB browser to read out the MIB tables of this node.
>It's all OK up to this point and the netmon daemon is correct configured
and
