HELP!! Any ideas sincerely appreciated!!! FYI. I am brand new to this list, so forgive me if this question is redundant. For a long time, I successfully used nmap_1.3.1. with winpcap on an WinXP pro laptop. One sad day, I went to scan a network, and NMAP just could not find any nodes, even with just a simple ping scan. Knowing I was past due to upgrade, deleted the old winpcap and NMAP, and installed winpcap_3_0 and nmap-3.55-SP2-win32. Still no luck. When I manually ping and then scan a test workstation on my network, here is the result: C:\Documents and Settings\nmap355>ping 192.168.0.101 Pinging 192.168.0.101 with 32 bytes of data: Reply from 192.168.0.101: bytes=32 time<1ms TTL=128 Reply from 192.168.0.101: bytes=32 time<1ms TTL=128 Reply from 192.168.0.101: bytes=32 time<1ms TTL=128 Reply from 192.168.0.101: bytes=32 time<1ms TTL=128 Ping statistics for 192.168.0.101: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 0ms, Maximum = 0ms, Average = 0ms OK that worked, so. C:\Documents and Settings\nmap355>nmap -sP 192.168.0.101 Starting nmap 3.55-SP2 ( http://www.insecure.org/nmap ) at 2004-08-31 12:01 Cent ral Standard Time Note: Host seems down. If it is really up, but blocking our ping probes, try -P0 Nmap run completed -- 1 IP address (0 hosts up) scanned in 12.048 seconds C:\Documents and Settings\nmap355> With a sniffer on the same PC running NMAP, I can see both the ICMP echo and TCP 80 Resets sent and the corresponding replies being returned from 192.168.0.1. Here are some of the things I have tried: 1) I double-checked that winpcap was activated by launching msinfo32 and verifying that the NPF driver was running. 2) I disabled all drivers (except TCP/IP) associated with the NIC 3) I tried a different NIC (my wireless card which worked is the past) 4) I verified that no firewall, VPN, or antivirus software was activated 5) I tried shutting off all services that I thought may be relative. 6) Gave up and subscribed to this mailing list where higher forms of intelligence are bound to exist.
