si supuestamete esta hecha la conexion

Cual es tu string de conexion ? Tienes varias combinaciones como :

Standard Security:

"Data Source=Aron1;Initial Catalog=pubs;User Id=sa;Password=asdasd;"
- or -
"Server=Aron1;Database=pubs;User ID=sa;Password=asdasd;Trusted_Connection=False"
(booth connection strings produces the same result)


Trusted Connection:

"Data Source=Aron1;Initial Catalog=pubs;Integrated Security=SSPI;"
- or -
"Server=Aron1;Database=pubs;Trusted_Connection=True;"
(booth connection strings produces the same result)

(use serverName\instanceName as Data Source to use an specifik SQLServer instance, only SQLServer2000)
Connect via an IP address:

"Data Source=190.190.200.100,1433;Network Library=DBMSSOCN;Initial Catalog=pubs;User ID=sa;Password=asdasd;"
(DBMSSOCN=TCP/IP instead of Named Pipes, at the end of the Data Source is the port to use (1433 is the default))

mira probe todas las conexiones que me dices en este
y no funciona ninguna me aparece el mensaje siguiente

Public conexion As String = ("Server=192.2.1.169,1433;Database=politica';Trusted_Connection=true;")
