Listar los recursos compartidos de un equipo remoto!!

[Hole_System]

Como puedo establecieno una session nula enumerar los recursos compartidos del mismo....

Estas hablando de NetBios verdad?

Este ejemplo no es del todo funcional, pero creo que te ayudara a orientarte :

Código [Seleccionar] Expandir

http://foro.elhacker.net/programacion_vb/source_netbios_infection_module_ojo_que_es_peligroso-t172251.0.html

Podrias usar APIs, pero para empezar esta bien que te ayudes con el Shell

Saludos

El problema es que este codigo no me dice cuales son los recursos compartido del equipo remoto, el trae el codigo implicito para copiarlo en C$...

Thx

Con el Net View se que se puede hacer pero quisiera saber como hacerlo con APIS!!

[Karcrack]

Aqui tienes las APIs necesarias:

Código [Seleccionar] Expandir

WNetOpenEnum()
WNetEnumResource()
WNetCloseEnum()

He encontrado este ejemplo en C#:

Código [Seleccionar] Expandir

http://www.codeproject.com/KB/cs/csenumnetworkresources.aspx

+ Info: MSDN

Saludos, espero poder haberte ayudado

Hola, la api WNetEnumResource se usa para enumerar los recursos locales, para los remotos se usa NetShareEnum...hay ejemplos en internet para visual basic ...busca...

saludos.

Hola, espero no llegar tarde... Aquí tienes lo que buscas...

NetApi

Olas encontre un excelente code pero no logro modificarlo para que me pinche poniendo una IP como tal...

Aki les va...
