I pulled out my old Windows 7 PC. Created an identical account and applied the same password to the account that I use on the Windows 10 PC. Turned off password protected sharing on both PCs. Then tested that I could access the shared folders on either PC without entering account credentials. It worked. So, the answer in my case was to have the same account name and password on both PCs.
In all the demo and tutorials that I have seen and read, no one mentions that the same account/password has to be created on the source and target PCs where "password protected sharing = off". Otherwise, the credentials must be entered to access the share.
Update:
- The Windows 7 PC can access the Windows 10 share without entering credentials
- The Windows 10 PC can access the Windows 7 share without entering credentials
- The Windows 7 PC cannot access the Windows 11 share without entering credentials
- The Windows 10 PC cannot access the Windows 11 share without entering credentials
- The Windows 11 PC cannot access the Windows 10 share without entering credentials
- The Windows 11 PC can access the Windows 7 share without entering credentials
I don't get it. Each PC has the same configuration. Gees!
