I 've to replace a HDD (by a new SSD) in a SME9 domain and was unable to join the same machine to domain.
Always complain about account exist and seurity police forbid it!
So I found this info =
https://support.microsoft.com/en-gb/topic/kb5020276-netjoin-domain-join-hardening-changes-2b65a0f3-1f4c-42ef-ac0f-1caaf421baf8about to add on registry:
Path: HKLM\System\CurrentControlSet\Control\LSA
Type: REG_DWORD (32)
Name: NetJoinLegacyAccountReuse
Value: 1
Maybe this registry hack can be merged to win10smb.reg or could we create a new .reg for it (or just update some documentation page).
I'm aware I'm no using SME10 so I'm not sure if it's still applies (I'd bet it does!).
