Hello!

I have domain account CONTOZO\user1 and local account SERVER\user1 with different passwords.
When I log into to the SERVER with a local account it sends several "Transitive Network logon" to the domain controller and locks domain account.
Why it happens?

netlogon.log from DC:
...
01/03 10:08:39 [LOGON] [2616] CONTOZO: SamLogon: Transitive Network logon of SERVER\user1 from SERVER (via DC1) Returns 0xC000006A
01/03 10:08:39 [LOGON] [2616] CONTOZO: SamLogon: Transitive Network logon of SERVER\user1 from SERVER (via DC1) Entered
01/03 10:08:39 [LOGON] [2616] CONTOZO: SamLogon: Transitive Network logon of SERVER\user1 from SERVER (via DC1) Returns 0xC0000234

    Hi,

    If the local and domain user have the same , it can generate a conflict,some process on member machine try by default to authenticate with the domain user name if the domain is not mentioned.
    I recommend you to use a different name to distinct between local and domain user to avoid this behavior.
