Here is the solution to "error code 0x80070035 network path was not found" on Windows Vista and Windows 7 Computers. Click on the "START" button, select "CONTROL PANEL", and go into "DEVICE MANAGER". Click on "NETWORK ADAPTERS", then click on "VIEW", and select "SHOW HIDDEN DEVICES". In the expanded view you will see a long list of numbered "MICROSOFT 6to4 ADAPTER". My Windows 7 Professional desktop had 200 of them. Right click and select "DELETE" on all but 1 of them. You can only do 1 at a time so it does take a while. When you have only 1 left, restart computer and enjoy being able to see your other network computers, including HOMEGROUP files.
