各位大哥帮帮忙，我的ADO连接怎么就不行呢

Question

客户端有一个服务程序 连接数据库如下：我现在的问题是，当我服务器数据库没有打开的情况下，我的客户端在执行  Connected:=True时候竟然没有任何反应，也不报错，也不执行下去，我写过try except ,但except也不执行，但是当我服务器端的数据库起起来后，连接就没有问题，真的让我很头疼啊，各位帮帮忙啊
v_String:=GetSQLServerADODefaultConnectString(A_DB_Name,A_Datasource);
        StringToWideChar(v_String,v_Connect,Length(v_String)*2);
        with AdoConn do
        begin
            AdoConn.Close;
            Connected:=False;
            LoginPrompt:=False;
            IsolationLevel:=ilCursorStability;
            CursorLocation:=clUseClient;
            ConnectOptions:=coConnectUnspecified;
            ConnectionTimeout:=15;
            CommandTimeout:=30;
            KeepConnection:=True;
            ConnectionString:= v_Connect;
            Connected:=True;
        end;
