I've enabled SMB sharing in OS X Lion and have added folders to share, it says 'Windows Sharing: On' with a green circle next to it (from the sharing window) and that to access the volume I will need to to go to \\192.168.0.17.

It also says that the OS X should be visible as 'macbook' in the network.

Both my WIndows 7 and OS X are connected to the same network, yet when I try to go to \\192.168.0.17 or from the Mac try to go to my Windows system (smb://192.168.0.6) the two OSs don't see each other.

Any ideas why?

Attempting to ping the Mac from Windows results in this output in the command prompt:
