pinging itself as a test for a network card?

[Guest]

A networked computer can ping but cannot be pinged.
However it can ping itself - is this an indication that the network card is
OK?
I.e. when it pings itself - does the request go out of the card's OUT to the
card's IN, or it somehow shorcuts and pinging itself proves nothing?

To find why your computer cannot be pinged, check whether you have firewall
settings enabled on your computer ? If so, you need to modify the settings
to allow ICMP requests and response.

Thanks,

Thank you, Priya.
Where from do I control firewall settings on w2k Pro?

PS. Nevertheless, will pinging itseld testify that the problem is not with
the NIC?

 

[Marc Reynolds [MSFT]]

Pinging a network card's own address successfully shows that the TCP/IP
stack is properly bound to the NIC, but doesn't rule out a problem with the
NIC.
As Priya mentions you should make sure you don't have a firewall on the
client and if you do that it allows ICMP traffic. Also the problem could be
the network cable or the hub/switch port you are plugged into.

Thans, Marc,

I tried another canle and used another slot in the router - no change.
Where do I control firewall settings from?
The router - Vigor2600X is said to have a built in firewall.
