NetUnjoinDomain function

The NetUnjoinDomain function unjoins a computer from a workgroup or a domain.

Syntax


NET_API_STATUS NetUnjoinDomain(
  _In_  LPCWSTR lpServer,
  _In_  LPCWSTR lpAccount,
  _In_  LPCWSTR lpPassword,
  _In_  DWORD fUnjoinOptions
);

Parameters

lpServer [in]

A pointer to a constant string that specifies the DNS or NetBIOS name of the computer on which the function is to execute. If this parameter is NULL, the local computer is used.

lpAccount [in]

A pointer to a constant string that specifies the account name to use when connecting to the domain controller. The string must specify either a domain NetBIOS name and user account (for example, REDMOND\user) or the user principal name (UPN) of the user in the form of an Internet-style login name (for example, "someone@example.com"). If this parameter is NULL, the caller's context is used.

lpPassword [in]

If the lpAccount parameter specifies an account name, this parameter must point to the password to use when connecting to the domain controller. Otherwise, this parameter must be NULL.

fUnjoinOptions [in]

Specifies the unjoin options. If this parameter is NETSETUP_ACCT_DELETE, the account is disabled when the unjoin occurs. Note that this option does not delete the account. Currently, there are no other unjoin options defined.

Return value

If the function succeeds, the return value is NERR_Success.

If the function fails, the return value can be one of the following error codes or one of the system error codes.

Return codeDescription
ERROR_INVALID_PARAMETER

A parameter is incorrect.

NERR_SetupNotJoined

The computer is not currently joined to a domain.

NERR_SetupDomainController

This computer is a domain controller and cannot be unjoined from a domain.

 

Remarks

Unjoining (and joining) a computer to a domain or workgroup can be performed only by a member of the Administrators local group on the target computer. If you call the NetUnjoinDomain function remotely, you must supply credentials because you cannot delegate credentials under these circumstances.

Different processes, or different threads of the same process, should not call the NetUnjoinDomain function at the same time. This situation can leave the computer in an inconsistent state.

A system reboot is required after calling the NetRenameMachineInDomain function for the operation to complete.
