I have a very strange problem.

I am unable to ping windows PCs on my local network, whereas they are able to ping my ubuntu laptop.

Another thing is I can actually VNC onto one of the PCs but cant to ping it. Only thing I am able to ping on the local network is localhost and the router.

Has anyone got any ideas why this may be happening?

The Windows computers might be treating the network as 'Public', or 'Network discovery' might be turned off. See if changing the network to 'Home' / 'Work' and turning on 'Network discovery' helps. – Soumya Jun 20 '11 at 9:52
Do you try to ping with name or with ip address? – Turbo J Jun 20 '11 at 13:37

You have firewall installed on windows machine which is configured to block ICMP packets.

Hi, the windows machines only have antivirus and no software firewall. Wierd thing is, if I boot from my backtrack 5 live CD I can actually ping these devices :S – Sidi0u5 Jun 20 '11 at 9:55
@Sidi0u5 Maybe its the windows standard firewall? – cularis Jun 20 '11 at 10:57
