Why some of the live PC in the workgroup; with static ip cannot be detected in the ip scanner 2.21. It detected as dead.
It is highly possible that these PCs are running a personal firewall AND/OR disabled the ECHO and ICMP on theses machines which makes it impossible to detect on the net.
Check the Windows XP SP2 firewall settings on the PC's that you cannot see.
I routinely use this on the network at work. I find Win2k pro/server, win2k3, winxp, Linux and assorted network devices (Cisco, Cabletron, Dell, Printers, etc) I find both domain and workgroup machines.
I've turned off ALL windows firewalls by GPO. If you're not seeing a machines Check both windows firewall and any firewall associated with a virus scanner (Norton/Symantec, Mcafee, Etc).
My results were cross-checked using Retina Eye Discovery Scan . I was using straight IP scan (no ports) w/64 threads and a 3 sec timeout. At 128 threads on a dual 1.4Ghz 2k3 server and a 1 second Timeout I did miss a couple (3 or 4) out of ~800. I have about a 50/50 split dhcp and static IP's.
I have the same Problem in my Workgroup.
But The guys i don't see have no static ip.
If i use the option "Scan dead hosts" i see the Hostname of them, but they are still dead. But the computers are online! Why don't i see them as alive?
i dunno mofo's I'm tryin to figure that one out myself
