[SOLVED] Accessible, but cannot ping

[CodingLover]

Of course. :)

Check your firewall settings. I don't know what firewall you are using but if it is the XP standard firewall, and it is turned on, then you will need to set the appropriate exceptions, or ping will not respond.

[CodingLover]

Yes Chris, I already did that too.

[Chris C B]

Have you tried with both firewalls turned off?

[Lost User]

As ChrisB said, turn off the firewall.

============================== Nothing to say.

There is another point: you must "Allow ICMP Echo Request", otherwise Windows won't send a reply back to sender. See e.g. http://wiki.phys.ethz.ch/readme/how_to_enable_icmp_echo_requests_ping_in_windows_xp_service_pack_2[^]

[CodingLover]

Yes it is. But nothing works.

Did it too. But no luck.

As all the suggestions you have received have drawn a blank, you will have to look deeper. The only remaining possibilty that I can see is that the file shares and RDP are using the machine name, and you have DHCP enabled in the router (you are using one, aren't you?), and the IP has changed from what you thought it was on a new lease. Otherwise, the whole thing is starting to look rather weird.

Next you can try a dns cache fluch on both machines (ipconfig /flushdns). If you are pinging by machine name then you can get issues. Next you want to look at the subnets the machines are on, and if they have routing between them set up correctly (I assume you can since other file and printer sharing seems to be working, but it is worth checking anyway).

============================== Nothing to say.

You obviously have physical connectivity between the two boxes. So exactly how is that physical connectivity achieved? And why do you care if you can ping? It isn't all that useful.

[CodingLover]

I have already did that. But no luck.

Simply connect them through a router. I am worried, because it is quite unusual. I can RDP and access shared folders but cannot ping. It's interest to me to know that. :)

I can access the file share and RDP using IP as well as the machine name. But cannot ping in either way. Earlier DHCP is disabled with my router, enable and tried the same. Still it's not working Chris. Wired!

FWIW: I just had an issue with ping failing between two machines of which one had not only TCP/IPv4 but also v6 enabled on the network adapter I was using; disabling that solved it for me. :)

Finally! That solve my problem too. I have enabled v6 a long time back, and haven't thought of it at this incidence. Thanks for pointing me Luc
