Answer 2

Hi Carlos Soto,

Since the issue is isolated to computers C and D, both running Windows 11, and persists even after formatting, the root cause is most likely related to SMB authentication or network profile settings rather than hardware or credentials. You can verify that both machines have SMB 1.0 disabled and SMB 2/3 enabled, as Windows 11 enforces stricter defaults compared to Windows 10. Also, ensure that both PCs are set to a Private network profile in Settings > Network & Internet, since Public profiles can block file sharing.

Another common cause is mismatched LAN Manager authentication levels. You can check this in Local Security Policy under Security Options > “Network security: LAN Manager authentication level” and set it to “Send NTLMv2 response only.” Additionally, confirm that the “Password protected sharing” option is disabled if you intend to use common credentials across devices.

If these adjustments don’t resolve the loop, I recommend running net use \\<computername>\share from Command Prompt to capture the exact error code, which can help pinpoint whether it’s a Kerberos or NTLM issue.
