Try to enable Microsoft SQL Server 2008 TCP/IP Protocol and set the Login mode to Mixed mode using C# without involve registry. Come across information below http://stackoverflow.com/questions/2266697/changing-sql-server-settings-programmatically
The information is really helpful but when try it in SQL Server 2008 using the C# source code given, it's not working very well. Then try to do some testing and finally it's work. I've added a line srv.Settings.Alter();
private static bool SetServerProperties()
{
#region standardize Connection String
string tempCatalog = "master";
string temp = @"Data Source=" + dataSource + ";Initial Catalog=" + tempCatalog + ";Integrated Security=True;MultipleActiveResultSets=True";
#endregion
SqlConnection sqlconnection = new SqlConnection(temp);
SqlCommand cmd = new SqlCommand("select @@ServerName", sqlconnection);
sqlconnection.Open();
string serverName = "";
try
{
SqlDataReader dr = cmd.ExecuteReader();
while (dr.Read())
serverName = dr[0].ToString();
}
catch
{
MessageBox.Show("Failed to Set SQL Server Properties for remote connections.");
}
Server srv = new Server(serverName);
srv.ConnectionContext.Connect();
srv.Settings.LoginMode = ServerLoginMode.Mixed;
srv.Settings.Alter();
ManagedComputer mc = new ManagedComputer();
try
{
Service Mysvc = mc.Services["MSSQL$" + serverName.Split('\\')[1]];
if (Mysvc.ServiceState == ServiceState.Running)
{
Mysvc.Stop();
Mysvc.Alter();
while (!(string.Format("{0}", Mysvc.ServiceState) == "Stopped"))
{
Mysvc.Refresh();
}
}
ServerProtocol srvprcl = mc.ServerInstances[0].ServerProtocols[2];
srvprcl.IsEnabled = true;
srvprcl.Alter();
Mysvc.Start();
Mysvc.Alter();
while (!(string.Format("{0}", Mysvc.ServiceState) == "Running"))
{
Mysvc.Refresh();
}
return true;
}
catch
{
MessageBox.Show("TCP/IP connectin could not be enabled.");
return false;
}
}
