  远程连接SQL Server 2000的解决方案:

  需求如下:需要远程连接外地的SQL Server 2000服务器。

  测试条件:一个公网IP,两个静态IP。

  具体步骤:

  一、ping服务器IP能否ping通

  观察远程SQL Server 2000服务器的物理连接是否存在。如果不行,请检查网络,查看配置,当然得确保远程sql server 2000服务器的IP拼写正确。

  二 在Dos或命令行下输入telnet 服务器IP 端口,看能否连通

  如telnet 202.114.100.100 1433

  通常端口值是1433,因为1433是SQL Server 2000的对于Tcp/IP的默认侦听端口。如果有问题,通常这一步会出问题。通常的提示是“……无法打开连接,连接失败"。

  如果这一步有问题,应该检查以下选项。

  1.检查远程服务器是否启动了sql server 2000服务。如果没有,则启动。

  2.检查服务器端有没启用Tcp/IP协议,因为远程连接(通过因特网)需要靠这个协议。检查方法是,在服务器上打开 开始菜单->程序->Microsoft SQL Server->服务器网络实用工具,看启用的协议里是否有tcp/ip协议,如果没有,则启用它。

  3.检查服务器的tcp/ip端口是否配置为1433端口。仍然在服务器网络实用工具里查看启用协议里面的tcp/ip的属性,确保默认端口为1433,并且隐藏服务器复选框没有勾上。

  事实上,如果默认端口被修改,也是可以的,但是在客户端做telnet测试时,写服务器端口号时必须与服务器配置的端口号保持一致。如果隐藏服务器复选框被勾选,则意味着客户端无法通过枚举服务器来看到这台服务器,起到了保护的作用,但不影响连接,但是Tcp/ip协议的默认端口将被隐式修改为2433,在客户端连接时必须作相应的改变。

  4.如果服务器端操作系统打过sp2补丁,则要对windows防火墙作一定的配置,要对它开放1433端口,通常在测试时可以直接关掉windows防火墙(其他的防火墙也关掉最好)。

  5.检查服务器是否在1433端口侦听。如果服务器没有在tcp连接的1433端口侦听,则是连接不上的。检查方法是在服务器的dos或命令行下面输入netstat -a -n 或者是netstat -an,在结果列表里看是否有类似 tcp 127.0.0.1 1433 listening 的项。如果没有,则通常需要给sql server 2000打上至少sp3的补丁。其实在服务器端启动查询分析器,输入 select @@version 执行后可以看到版本号,版本号在8.0.2039以下的都需要打补丁。

  如果以上都没问题,这时你再做telnet 服务器ip 1433 测试,将会看到屏幕一闪之后光标在左上角不停闪动。恭喜你,你马上可以开始在企业管理器或查询分析器连接了。
