I cannot see PC W2K from PC XPHE SP2 in lan
Dear all,
Have anyone experienced similar problem?? I have a small lan 3 PC connected thru an hub to an ADSL router. They receive IP from DHCP server (provider). When I try to connect from PC having W2K Pro (Sygate firewalled) to other two (XP) I can easily. When I connect I connect directly thru a cross cable with input fixed IP I cannot access to XP from W2K, but exactly the opposite. When I try to connect from one of two PC XP to W2K I cannot see it. I tried several solutions before writing this note with no success: when I ping the IP address of W2K PC I get time out error. If I run nbtstat - n, I see W2K PC. This is what I get from IPconfig /all (the addresses are modified for privacy reason but are similar): PC con W2000 Pro (english) Windows 2000 IP Configuration Host Name . . . . . . . . . . . . : PIPPO Primary DNS Suffix . . . . . . . : Node Type . . . . . . . . . . . . : Hybrid IP Routing Enabled. . . . . . . . : No WINS Proxy Enabled. . . . . . . . : No DNS Suffix Search List. . . . . . : mycompany.mycompany.com Ethernet adapter Local Area Connection: Connection-specific DNS Suffix . : mycompany.com Description . . . . . . . . . . . : 3Com 3C920 Integrated Fast Ethernet Controller (3C905C-TX Compatible) Physical Address. . . . . . . . . : 00-06-5B-E5-AA-94 DHCP Enabled. . . . . . . . . . . : Yes Autoconfiguration Enabled . . . . : Yes IP Address. . . . . . . . . . . . : 100.12.0.xxx Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : 100.12.0.x DHCP Server . . . . . . . . . . . : 100.12.0.x DNS Servers . . . . . . . . . . . : 192.100.0.34 Lease Obtained. . . . . . . . . . : 31 March, 2005 10:39:40 Lease Expires . . . . . . . . . . : 01 April, 2005 10:39:40 PC1 Windows XP HE SP2 (Italian) Configurazione IP di Windows Nome host . . . . . . . . . . . . . . : PLUTO Suffisso DNS primario . . . . . . . : Tipo nodo . . . . . . . . . . . . . . : Sconosciuto Routing IP abilitato. . . . . . . . . : No Proxy WINS abilitato . . . . . . . . : No Scheda Ethernet Connessione alla rete locale (LAN): Suffisso DNS specifico per connessione: Descrizione . . . . . . . . . . . . . : National Semiconductor Corp.

I already check with WinXP firewall deactivated, but I cannot ping on W2K, there is no wasy to see the PC. ================================= I have dealt with similar posts before, and in each case the problem was caused by a forgotten firewall, or a firewall that was supposedly de-activated but remained active until uninstalled. If you are unable to find out what's going on, install a network sniffer (e.g. Ethereal) and see what happens to your packets. |
