Hi !
I am trough the Network and landed on a Server I can ping from another server in the network, but i cant ping it from my PC ?
From the server i landed on i can ping microsoft.com so it has connection to the internet and is not only running over the server i was on before.
any ideas ?

in lots lf lans most pcs have ports blocked to outside the network.
this pc can be something like that (i dont think so though), more likely is that the pc you cant ping is good firewalled

well i know it isnt firewalled, perhaps behind a router ? but i can do everthing on the machine from a server in the same network, but i cant do it from my pc !
i cant ping it, scan for open port or do anything else !
and whats with port 80 ? didnt understand...

perhaps a firewall blocks external ping requests for this purpose

If it's behind a router (I.E. Cisco) then an ALC might have blocked IMCP replies for your subnet. Are they using DHCP or are you static? Corporate or small business network? I would go to the server and see if admin software is blocking you like Tivoli or something. Also change your IP to a different address and see if it works. The restriction could be in a DHCP pool only. Is this on something like a cable modem (witch it doesn't sound like it is) it could be hard ware filters.

ICMP Ping replies might be disabled in the SERVER...!!

Yes sometimes isp's do block icmp (ping) . My isp too does it or maybe u router is set to do it .

Ok I think you said you could ping the "server1" from "server2" but you can't ping "server1" from your home PC. What kind of access do you have to "server2"? If any of the servers are running Windows 2003 or XP you can turn on remote desktop and log into "server1" and install a port redirector. Or if you can VNC/remote desktop with "server2" then you can install a go vuln scanner like retina and scan "server1" from "server2". The trick here is to see how much info you can get about the server then figure out what you want to do with "server1".

Well, between Server1 and Server2 is everything possible, by remote desktop i have full axx on server2 over server1 !
i think server2 is behind a hardware firewall or something like that.
