Remote Access To SQLServer 2005

Hi,

I installed SQLServer with a instance using the following cmd:

/qn INSTANCENAME=MYINSTANCE ADDLOCAL=All SQLCOLLATION=Latin1_General_CI_AI=Latin1_General_CI_AI PIDKEY=ABCDE12345FGHIJ67890KLMNO SECURITYMODE=SQL SAPWD=Pass SQLAUTOSTART=1 ENABLENETWORKPROTOCOLS=0

When I try to connect to the server using VS2005 (VB) using the code:

Dim instance As System.Data.Sql.SqlDataSourceEnumerator = System.Data.Sql.SqlDataSourceEnumerator.Instance
Dim table As System.Data.DataTable = instance.GetDataSources()

For Each DRrow As DataRow In table.Rows 'DRrows
C1List1.AddItem(DRrow(0).ToString & ";" & DRrow(1).ToString & ";" & DRrow(3).ToString)
Next

I can see the Server Name, but not the Instance Name.

I've already checked the SQL Configurantion Manager, and I've allowed this instance to accept remote connections (created by the cmd install command).

NOTE: I'm testing the connection on a Domain, but only using the SA account (SQLmode).

Can somebody help me?
Thanks.

PS: I also created an Firewall exception in Windows on the port 1433.
