Cause

Hay muchas causas posibles para estos errores. En esta instancia, la contraseña del dominio se cambió después de crear la sesión de migración.

Resolution

Uno de los siguientes pasos puede ayudar a resolver este tipo de problema:
1) Actualice las credenciales de administrador en las propiedades de la sesión de migración en Unisphere para que coincidan con la contraseña actual.
2) Cree un usuario administrador local en el servidor CIFS de VNX mediante Microsoft Computer Management (MMC). Configure las credenciales de administrador en las propiedades de la sesión de migración en Unisphere para que coincidan con esta cuenta de usuario recién creada.
3) Si la contraseña tiene caracteres especiales, intente cambiarla por una alfanumérica.
