Java程序与SQLserver2005连接不上.（内有详细说明）高人指点..
连接数据库代码.... 
  try 
{ 
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver"); 
} 
catch(ClassNotFoundException e1) 
{ 
e1.printStackTrace(); 
} 
try 
{ 
Connection con = DriverManager.getConnection("jdbc:sqlserver://localhost:1433;DatabaseName=SBookMC","",""); 
Statement sql = con.createStatement(); 
ResultSet rs = sql.executeQuery("select*from ManagersTable"); 
while(rs.next()) 
{String name = rs.getString("LoginName"); 
String password = rs.getString("PassWord"); 
String number = rs.getString("ManagerNum“) 
jTextArea.setText(name); 
jTextArea.setText(password); 
jTextArea.setText(number); 
} 
con.close(); 
} 
catch(SQLException e1) 
{ 
e1.printStackTrace(); 
} 

eclipse控制台的报错信息：com.microsoft.sqlserver.jdbc.SQLServerException: 用户 '' 登录失败。该用户与可信 SQL Server 连接无关联。 atcom.microsoft.sqlserver.jdbc.SQLServerException.makeFromDatabaseError(Unknown Source)

虽然报的是 用户无效...但是一直怀疑是TCP的端口问题，或者是驱动包的问题 
我在DOS下面使用 netstat -an 查询的协议端口中没有 TCP的1433端口.... 而且SQLserver2005运行的进程PCB中的PID号所对应的tcp端口是1434...请高人指点 我这个小白一下.....谢谢了

------解决方案--------------------
可以把程序中的端口改成1434试一下啊！
