When all the computers on my LAN were running Window 7, I setup WORKGROUP. The computer I used to do that is no longer in use. I have a total of four computers on my LAN. Iâ€™ve kept Window 7 on my HTPC because I want to keep Windows Media Center. The other three were replaced With Windows 8 computers that have since been upgraded to Windows 10. I can access the HTPC shared folders from the Windows 10 computers, but I cannot access the Windows 10 shared folders from the Windows 7 computer or from another Windows 10 computer. I am asked to provide and account name and password. I enter the account name and password I use to login to those computers, but it fails. Before I upgraded to Windows 10 from Windows 8.1, I wasn't asked for the account name and password. What can I do to access the shared folders on the Windows 10 computers?
