no need to install LookLAN elsewhere. A couple comments/questions first Mcaffee Network Mgr IDs 192.168.1.100 that is your printer Mcaffee Network Mgr IDs 192.168.1.105 which isn't seen elsewhere. If you look again, is it still there or disappeared? If still there, do you have any other network connections (e.g. bluetooth) that aren't connected to your LAN ethernet cables? Do you mean from Office9100? So you're saying when you look from Office9100 at My Network Places it sees all 5 computers (counting itself)? LookLAN is installed on Office9100, is that correct? So you mean from Office9100 you can see all 5 computers from My Network Places but LookLAN on that same computer doesn't see all 5?? Could you verify this oddity again? And check the Port scan range you are using in LookLAN Also, could you remove the ISP cable from the router and turn off all the firewalls on all the computers. Wait 5-10 minutes and check LookLAN and My Network Places per Computer again /***** Edit ****/ And which computer is McAfee Net Manager running on?
