I’ve been out at a client’s trouble shooting some network issues on small network that supports both Windows Xp and Vista machines. While tracking the issue down to a faulty NIC , I noticed that I was unable to ping the Vista pc’s but was able to ping the Windows XP clients.
This is due to the fact that the Windows Vista Firewalls default is to deny ICMP messaging.
The quickest way to disable this was through the command line:-
netsh firewall set icmpsetting 8 disable
After I was all done I did re-enable for security reasons.
netsh firewall set icmpsetting 8 enable
