Возвращает Button1Click код 2224, подозреваю, что чтото не так с строками, а в частности с wchar_t *UserGroup. Кто поможет?

Это Вам функция NetUserAdd "говорит" что пользователь уже есть.

В файле <C Builder install dir>/include/lmerr.h находим

Код:

#define NERR_BASE       2100
....
#define NERR_UserExists         (NERR_BASE+124) /* The account already exists. */
...
