Hello, I've added a new laptop to my home network (now 3 computers, all of them with win 7 ultimate 64) . I didn't use home group because i don't like it, so i configured everything manually and everything worked great, file sharing. printer sharing, everything. And then I added a password to my user on the new laptop to protect it and the sharing between the laptop and the two other computers stopped working. when i try to access the laptop from another computer it reports i have no access, and when i try to access one of the computers from the laptop it asks for a user name and password. i uninstalled firewall - didn't help. reinstalled. i removed the password - problem solved. added password again - problem returns. all users on all computers are administrators. maybe something about group policy... anyone have an idea ?
