Why would an operating system allow you to disable ICMP?
ICMP has no security issues and IS a vital part of what keeps TCP/IP
working properly.
Allowing users to configure/disable this is as silly as when clueless
firewall admins block all ICMP and then wonder why their users have
problem accessing the network and browsing the internet.

Check that Windows has the Service running that responds to ICMP

If you are running XP then check Control Panel>>Windows

that you want.
Thank you,

Your setup sounds fine and the ping requests are leaving the other
machines AND arriving at M1. However, M1 chooses not to reply. I don't
see any reason from a network perspective that this is happening. If
it's a Windows machine, have you tried reinstalling? :)
