cannot ping

80 New Member
I have a computer on a LAN that I cannot ping from any other machine on the LAN, nor can that machine ping other machines on the LAN. The machine can get out via the gateway to internet, can send e-mail, etc. It just cannot be directly reached via it's internal IP address.

Any ideas what I need to configure to change this? BTW, this machine (and others on the LAN) have static IP addresses.

how high are the firewall settings on the computer that can't be pinged and what firewall/security program are you using?

Windows firewall is disabled. There is no internal firewall, only the external connection is firewalled.

BTW, machine is Windows XP pro, as are most others on the network.

Okay, this is weird. The computer that cannot reach out with ping can reach the same machine at the same IP address using that machine's internal apache web server. What could be blocking a ping but allow connection via a browser and web server?

Seems like the problem isn't on the new machine, but the old one. There was a firewall on the original machine that was part of the virus scan software, which I didn't know about. Disabled it and a few minutes later, all seems to be working.

if you want the firewall still all you have to do is add the ip to the exceptions, since its a network, just add the ip range.

I need to do a ping scan of a subnet. I can Enum through the IPs and do this, but it takes over 5 minutes as I can only create 1 process at a time. Does anyone know how I can create multiple Ping Processes so as to send out 255 pings at once? (sort of a reverse ping flood). FYI: using the " -n 1" switch with Ping will cause it to only send...
