I assume from what you are saying that Cougar is your Windows 7 computer. If so the problem you have lies with the changes in security with Windows 7+. You will need to ensure that the windows 7 firewall is configured to allow "File and Print Sharing". You will also need to ensure that you set the folders you wish to share access to are configured correctly both on the share and the NTFS tab.

Do both of your computers belong to the same workgroup? Another issue could be Windows 7 provides device discovery, using the "Networking and Sharing Center" you should check to see if device discovery is enabled.

Also when connecting your windows 7 machine to the network for the first time you will of been presented with a box asking you to identify the type of network connection which is active. This of course should be set to Home.

I have give you a basis to start troubleshooting, please let me know how you get on.

configured to allow "File and Print Sharing" = enabled 4 both private & public / shared = ok / same workgroup = ok / network discovery = enabled 4 poth private & public / box asking = i did not get this wizard - where is that and how can i do that manually? – MoonLight Feb 23 '11 at 10:08
This is done through the network and sharing wizard, it should show your computer and a little topology diagram showing how you connect to the internet. Around there it should say Work/Home/Public – JamesK Feb 23 '11 at 10:15
it seems problem was about file and printer sharing & network discovery & it has solved / but let us to what is difference between private and public in this network ? – MoonLight Feb 23 '11 at 10:17
These options are to control network devices seeing your computer. Public as the name implys allows your computer to be discovered where as private does not. – JamesK Feb 23 '11 at 10:25
