I'm trying to ping a ip adress in DOS, let's say i'm trying to ping www.computing.net ( that is just an example, since I have the same problem with ANY ip adress)but I get this msg all the time : response from 207.253.205.9: destination unreachable but that is not my ip, mine was 207.253.205.98 I phoned my isp ( 3 times ) and got 3 different answers : 1-your firewall is blocking it ( which I disabled but same problem)2- The ip you are trying to ping ignores the ping ( wrong since every ip adress does that) 3- We don't know ( great..) Any help would be appreciated. Thx

Try this now: Ping 127.0.0.1 If you do not get a normal ping response, then your TCP/IP software on your system is not setup correctly or the WINSOCK is damaged? 127.0.0.1 is the Local Host in your system. When you ping that IP address, it never leaves the system. Does not go out the ethernet cable, but wraps back through the software in your system. It should alway work or something in your software is blocking the TCP/IP software interface. Now if you are trying to ping an IP address, and it keeps coming back that a different IP address is not reachable, you have some sort of proxy server or HOSTS hijack software on your system. Run SpyBot to check. Also, look in C:\Windows folder for a file named HOSTS (no extension, there should be a file named HOSTS.SAM). If you have a HOSTS file, try renaming it to HOSTS.BAK and see if that changes your problem. Your ISP could have been right the first time. Your Firewall software could be messed up and causing the problem. Disabling it is not the same as fixing a problem it is causing. There is one other possibility. Due to the recent problems with virus flooding the Internet, some ISPs have been blocking Ping requests and responses coming into their Networks. They or another ISP could be redirecting all PINGs to a specific router that is not reachable and producing the error you are getting. But you would still be able to ping 127.0.0.1 and your connection router. Try doing a tracert to an IP address. And note the first (1) IP address. This is the IP address of your connection router, or the first router on the ISPs network you are connecting through. You should be able to Ping that router without any problem. If any problem or the same error, then it is cause by a software problem in your system.

Thanks for answering JackG When I try to ping 127.0.0.1 everything works fine, and I have no HOST file in c:\windows and don't you think that if it was my firewall messed up when I disable it it would work? And I can't tracert either, same error msg as ping : destination unreachable but netstat works though... Any other ideas ?

Hi, Check your C:\windows\system32 for the hosts file. On mine it's in the C:\windows\system32\drivers\etc Or just search for it in the windows dir through windows search...

Nope..nothing there either...

it's prob your isp.. can you ping your isp's gateway? i'm having the same issue here. i can't ping anywhere in "the world" but i can ping local network computers, and to my isp's gateway. find out what your ip address is, and change the last number to a 1. for example: 32.64.5.23 = 32.64.5.1. and ping it. or you can call and ask what their gateway ip address is. if you get a reply then you know it's not on your end. good luck
