Funny question:

I have 3 machines...1 being a server.
I disabled IPv6 on all machines and now I can't ping from one machine to the other two machines.  I was able to ping before the disabled IPv6 option.

Are any of the machines using IPv6 including the server? You may want to disable it on all machines but if not, what is the reason you disabled it to begin with?

You should verify that DHCP is correctly configured. If you don't use DHCP check your machines IPv4 addresses.

I have IPv6 disabled on ALL machines, including server.  The reason I disabled it was for testing purposes.  One of my collegues mentioned that they had disabled it on a live environment and the same issue occured...he was not able to ping across, just like what's happening to me now.
But we can't figure out why?

Are you trying to ping the interface via the IPv4 address or via the Hostname?

If its via the hostname the issues could be DNS related i.e. your server doesn't have an A class address fo your clients only AAAA addresses.

Disable IPv6 in the registry for good measure.  Then reboot the machine.

Now test, but if it's still not working, then try this for testing at cmd prompt.
net stop dnscache

What I'm trying to figure out is WHY when I disable the IPv6 option, I'm not able to ping across.  I'm not trying to completely disable the option.  I just wanted to figure out why I can't ping when I disable this option.

...which is what we are trying to help you discover.  Is the ping successful when disabling the cache?

Check your Windows Firewall settings & make sure that the IPv4 ICMP in/out rules are enabled.

I know disabling IPV6 on windows 7 can delete homegroups because they are both tied to "Peer Name Resolution Protocol" try checking the services to see if this is running.
