Cannot ping two computers on same subnet

I have a MN-700 Router with a desktop and a laptop connected to it. Both
computers are running Windows XP. Both machines are able to obtain an IP
from the MN-700 and can access the internet without problems. The only
problem that I am having is that niether machine can ping the other. The
machines are able to ping the default gateway. I do not have ICMP blocked on
the router.

Any suggestions on what the problem may be?

Thanks,

Set the software firewall(s) on the computers to allow pings. The
setting in the MN-700 only has to do with the Internet pinging your
MN-700 & nothing to do with the computers behind it pinging each other.

So once again it has to be a software firewall setting that is causing
this issue or your TCP/IP stack is hosed.

If your question is worth asking, it's worth posting.

If it’s not worth posting you should have done a search on
http://www.google.com/ http://www.google.com/grphp?hl=en&tab=wg&q= or
http://news.google.com/froogle?hl=en&tab=nf&ned=us&q= before wasting our
time.

If I sound hostile or arrogant you need to read the following before

My Firewall is set up to allow incoming ICMP requests. If my TCP/IP stack is
shot, how do I repair it?

That is a software firewall like Norton Internet security, Black Ice
defender, zone alarm, McAfee Firewall, or the Windows XP firewall are
all examples of the more likely case of this problem.

The answer for fixing a busted TCP/IP stack on Windows XP is that it
depends on which service pack you are running. If you are running
service pack 2 it is most likely that you have the Windows XP firewall
enabled.

I am running XP with SP2. I do not have any firewall hardware. I only have
the XP SP2 firewall. It is currently on. I disabled it and had the same
problem. How do I rebuild the TCP stack?

You can try the articles I found at the following link.

http://www.support.microsoft.com/sea...de=a&x=12&y=16

BTW it is a search for "TCP/IP rebuild" (without the quotes of course)
on Windows XP specifically over at
http://www.support.microsoft.com/search/?adv=1 if you want to try it for
yourself, just remember to select "Windows XP" in the "Search Product"
field & "TCP/IP rebuild" (without the quotes of course) in the "For" field.
