Windows 7 Can´t access folders located in one of my computers from the others

To address the issue of shared folders from laptop 1 not being accessible from the other machines (PC and laptop 2) in your Windows 7 Ultimate homegroup network, you can troubleshoot by following these steps: 1. Ensure HomeGroup Settings: - Verify that all computers are connected to the same HomeGroup with the correct HomeGroup password. - Check the HomeGroup settings on laptop 1 to ensure that the shared folders are set to be accessible by other HomeGroup members. 2. Check Network Discovery and File Sharing: - Make sure that Network Discovery is enabled on all machines. Go to Control Panel -> Network and Sharing Center -> Change advanced sharing settings -> Turn on network discovery. - Confirm that file and printer sharing is turned on for the network profile (e.g., private, home) on all three machines. 3. Share Permissions: - Review the sharing permissions of the folders shared from laptop 1. Right-click on the shared folder -> Properties -> Sharing -> Advanced Sharing. - Check that the Everyone group has Read permissions or Full Control if desired. 4. File and Folder Permissions: - Next, check the file and folder permissions of the shared folders on laptop 1. Right-click the folder -> Properties -> Security -> Edit. - Make sure that the appropriate user accounts or the Everyone group has the necessary permissions to access the shared folders. 5. Firewall and Antivirus: - Temporarily disable the firewall and antivirus on laptop 1 to see if they are blocking the file sharing. - Add exceptions or rules in the firewall settings on laptop 1 for file and printer sharing. 6. Restart the Computers: - Restart all three computers after making changes to settings to ensure that the changes take effect. By following these steps, you should be able to troubleshoot and resolve the issue of shared folders from laptop 1 not being accessible by the other machines in the Windows 7 homegroup network.
