I am not sure if I should be posting this in the security area or the networking area. I apologize if this is the wrong place.
I really have wierd problem-
I have Netgear FVS318 router on DSL on a single network (windows 2000 server) 192.168.1.X ; 255.255.255.0
I have accounted for all the machines except one (192.168.1.12)
I can't ping this machine, however when I do a TCP port scan , I am showing port 25 and 110 open
UDP port scan reveals several different ports.
I have checked for everything network printers and any other network devices, but no answers. Even the Netgear router does not list this IP in the attached devices list. I can see that there is byte transfer from this IP using etrust Intrusion detection and Kerio network monitor
Please advice, Is there anything I am missing to check.
