I have setup a Homegroup for a desktop and 2 laptops. All computers have joined the Homegroup and the 2 laptops can see files on the other computers. However, when I try to access the other computers from the desktop, I'm asked to signin. I enter the other computer user's name and since neither has a password I just click on OK. Then I get a message that says I don't have permission to access the files.
I left the Homegroup, restarted my Desktop, and re-Joined the same Homegroup. Got asked to sign-in (coputername\username and no password) and then got rejected.
I went ahead and added a password to one of the laptops. I restarted my Desktop again and this time when I was asked to sign in , I used computername\username and password. It let me access the files then.
At least I can work with the files now. However, it is annoying to sign-in each time and I and now when I reboot the laptop, it pauses until I give it the password. That laptop isn't asked to sign-in when accessing the Desktop files through Homegroup.
Any idea why one computer must sign-in and others don't?
