Win7 (and Vista) has some issues broadcasting its availability on a network.
You could try these changes to your Win7 box:-
Firstly, configure Sharing and Discovery:
- Navigate to the Network and Sharing Center via the Control Panel
- Click on the down arrow icons and select ON/OFF as follows:
Network Discovery - ON
File Sharing - ON
Public Folder Sharing - OFF
Printer Sharing - ON
Password Protected Sharing - OFF
Media Sharing - OFF
Next, configure the folder you want to share:
- Select the folder
- Right-click and choose ‘Share’ from the menu
- From the drop-down box select the Everyone (All users in this list) account, making sure permissions are set to ‘Reader’
- Click the buttons Add, Share and Done.
Here are some further registry ‘tweaks’ if this doesn’t work:
