Problema con Windows server 2003

[ARKHANTHOS]

Trato de instalar un soft para la creacion de llamadas Voip, este va en windows server 2003.

Lo tengo en 1 an 1 españa, el problema es que al hacer update del programa , la conexion del ftp se pierde me da este error

System.Net.WebException: The remote server returned an error: 227 Entering Passive Mode (91,xxx,xxx,xx,xxx,xxx)

Alguien sabe que es el error o podra echarme una mano???

La actualizacion es para la base de datos, al momento de dar update la conexion no se da porque aparece ese error.



Gracias.
