I am not able to ping other computers on a LAN. The computers I am trying to ping are all behind the firewall. Also, the computers are utilizing TCP/IP with correct DNS/WINS. IWhen I attempt to ping the NETBIOS name DNS resolves the IP Address. If I review DNS I see all the computers listed by their NETBIOS name and IP Address. I cannot succesfully ping either NETBIOS or IP Address. I have tried to TELNET also using C:\ TELNET <computername> 3389 for the MS Remote Desktop port and C:\ TELNET <computername> 6129 for the Dameware Mini Remote control. Could someone please shed some light on this for me. Thank you.
