Hi Jim,
My firewall are disable on both servers. But you give a clue with your SNMP 2 ways, we have create a Community strings named hpsimlab, i remember in my firts initial test i was keep public by default. When i set the Community strings to public my "Identify sysyem" Pass! After that everthing seen to be normal.
Now my task is to get through a another domain, I think i'll have to talk a lot with the network guy in my organization.
Thanks a lot for your help guys.
