NetJoinDomain
Начитался MSDN, написал программу. Цель: перевод компьютеров из домена в рабочую группу. Код ниже

Declare Function NetJoinDomain Lib "NETAPI32.DLL" (ByVal lpServer As String, ByVal lpDomain As String, ByVal lpAccountOU As String, ByVal lpAccount As String, ByVal lpPassword As String, ByVal fJoinOptions As Long) As Long

Public Function SetWKGrpWithAPI(WorkGroupName As String)
'This function joins a Windows 2000/XP workstation to a workgroup.
'It wraps the NetJoinDomain API from NETAPI32.DLL. This API is
'only available from Windows 2000 and will not work for Windows NT4.0.

Dim NullTerminatedWkGrpName As String
Dim I As Integer

'Insert a vbnullchar character after each character in the workgroup name.
'Failure to insert the vbnullchar characters may lead to corrupted
'workgroup names.
For I = 1 To Len(WorkGroupName)
    NullTerminatedWkGrpName = NullTerminatedWkGrpName & Mid(WorkGroupName, I, 1) & vbNullChar
Next

SetWKGrpWithAPI = NetJoinDomain("", NullTerminatedWkGrpName, "", "", "", 0)

End Function

Вызов: call SetWKGrpWithAPI("WORKGROUP")

Если не указывать NETSETUP_JOIN_DOMAIN (0) в fJoinOptions машина должна лезть в рабочую группу. Короче, не работает, вылезает ошибка

Есесно, привилегии все имеются.

Помогите солюшеном по данному вопросу.
