i have tried everthing for weeks

Presumably all the computers are running Windows 7, which they have to. Have you tried setting up the Homegroup from scratch? If not, here's how: 1. On each of the computers, go to Control Panel > All Control Panel Items > Homegroup > Leave the Homegroup and click Leave the Homegroup. If all the computers leave the Homegroup, it will no longer exist, so it‘s effectively deleted and can be setup again. 2. Now create the Homegroup on one computer. Go to Control Panel > All Control Panel Items > Homegroup > Create a homegroup > Select the folders you want > Next and make a note of the password that will be used by other computers to join the Homegroup. 3. On the other computers, go to Control Panel > All Control Panel Items > Homegroup > Join now and type in the password.
