Adding local groups to a NT Workstation

Adding local groups to a NT Workstation

Question:
I am trying to write an app that can add local groups to the NT security database on an NT workstation. When I use the netlocalgroupadd() function, I get an error saying that I do not have permission.

Answer:
According to the MSDN, “Only members of the Administrators or Account Operators local group can successfully execute NetLocalGroupAdd.” But given than you actually have the correct rights, then the following code should work.

Option ExplicitPrivate Const NERR_Success             As Long = 0&Private Const LocalGroupMembersInfo3   As Long = 3&Private Type LOCALGROUP_MEMBERS_INFO_3   DomainAndName                       As LongEnd TypePrivate Declare Function NetLocalGroupAddMembers _   Lib "netapi32" _   (ByVal psServer As Long, _    ByVal psLocalGroupName As Long, _    ByVal level As Long, _    pPtrBuffer As Long, _    ByVal membercount As Long) As Long    Public Sub Main()   AddUserToLocal "xxx_group", _                  "myuser", _                  ""End SubFunction AddUserToLocal(ByVal xi_strGroupName As String, _                        ByVal xi_strUserName As String, _                        ByVal xi_strServerName As String) As Boolean   Dim p_lngPtrGroupName   As Long   Dim p_lngPtrUserName    As Long   Dim p_lngPtrServerName  As Long   Dim p_lngMemberCount    As Long   Dim p_lngRtn            As Long      ' Convert the server name to a pointer   If Len(Trim$(xi_strServerName)) = 0 Then      p_lngPtrServerName = 0&   Else      p_lngPtrServerName = StrPtr(xi_strServerName)   End If   ' Convert the group name to a pointer   p_lngPtrGroupName = StrPtr(xi_strGroupName)      ' Convert the user name to a pointer   p_lngPtrUserName = StrPtr(xi_strUserName)      ' Add the user   p_lngMemberCount = 1      p_lngRtn = NetLocalGroupAddMembers(p_lngPtrServerName, _                                      p_lngPtrGroupName, _                                      LocalGroupMembersInfo3, _                                      p_lngPtrUserName, _                                      p_lngMemberCount)      If p_lngRtn = NERR_Success Then      AddUserToLocal = True   Else      AddUserToLocal = False   End If   End Function
