Cannot ping other computers on LAN or connect remotely.
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.
Also you might want to check the pc's to make sure they dont have a software based firewall on them...
Ie. windows firewall, norten internet security, macafee, ect....
If you could describe your network setup it will also help us troubleshoot it better...
Good Luck

The computer I am pinging from and to are all behind the same firewall on a private network using the same subnet. I have tried the TRACERT command and it is timing out at the first hop. I can however ping some of the nodes but not all of them. ????
on the ones that you cannot see can you check them for a software base firewall like windows firewall, norten internet security, macafee, ect....
if so try disabling them just for a little bit and re-test ping and tracert

The node I am using in this example that I copied and pasted and masked the NETBIOS name does have the windows firewall and Mcafee services disabled:

Our IP range goes from 53.100 to 53.200. Another wierd thing I just discovered is that in Network Neighborhood the computers are listed but as a domain admin if I go to access that computer it tells me Network Path not Found.

The file and print sharing did it. It is amazing that as technical guys we look right over the most obvious answers. Thank you so much. I also added port 6129 as an exception for the Dameware Mini Remote Control.
No prob.... congratz on getting it working ... glad to help......
If you Are behind the firewall are you on the same subnet or a different one?
If on a Diff subnet Have you tried running a tracert command to make sure your requests aren't going somewhere strange to try and get to the other subnet
