telnet 1433突然不通?

时间:2021-10-16 15:21:35
程序一直运行正常,前两天突然不能访问 检查后发现连接 SQL Server2000出错,进一步测试本机访问一切正常,但通过另外一台机器访问怎么也连不通,telnet <IP> 1433 不通,把端口改成其它任何端口都可以访问,请问这是什么原因?
已知信息
1.操作系统已打SP2补丁
2.SQL Server2000已打SP4补丁
3.防火墙已关闭
4.程序以前运行正常
5.改成其它端口可以访问,只有1433不行
6.发现windows2003服务器被创建了一个full用户,

高度关注..

#2


是网络问题吧,是不是1433端口被网管封掉了?

#3


但最的发现有2台服务器都是这种情况,同网络中其它SQL Server服务器正常,网络应该是没有问题的

windows server 2003 SP2会关掉一些东东,具体忘了在哪里见过.
建议去百度或者google一下,前几天有人遇到类似的问题,
好像是硬件网卡的问题.

#6


安装微软发布的最新补丁DEMS

#7


改端口3433试试

#8


如何打开1433端口?
本地连接-〉属性-〉TCP/IP属性-〉高级—〉选项-〉TCP/IP筛选属性    
然后自己添加就可以了。

#9


关注一下1433端口的使用情况
用netstat -n

我也遇到了!
郁闷中

以前都好的
新装了下服务器就这样

回复第8楼:
本地连接-〉属性-〉TCP/IP属性-〉高级—〉选项-〉TCP/IP筛选属性   
所有都是“全部允许”

netstat -an 结果如下:监听正常
TCP 0.0.0.0:1433  0.0.0.0:0  LISTENING

#13


1433是否被占用?

#14


另外,我换其它任何端口,都能连接,现在就是奇怪:为什么突然间1433端口不能使用?其它任何端口正常,网管也没做任何限制。

#15


1433应该没有被占用,因为我用1433端口时,本机访问是正常的,只是远程无法访问,

我换端口访问是没有问题的,现在是想找出问题出在什么地方,因为我现在同时有2台机器都出现这种情况

#19


感觉不应该与端口有关?

#20


我感觉是中了什么针对SQL Server的病毒或木马,但诺顿查不出来

#21


我们以前也出现数据库莫名其妙的问题,与这个有点类似,
发现打了补丁后系统运行就不正常,

最后逼得没有办法,重新启动一下机器进行逐一排查,最后就好了,你也可以试一试 ,
这也是下下策了,

#22


系统莫名地创建了一个“full”用户

#23


是不是被黑了?或是成僵尸了?
卡巴斯基,杀之!

#24


中毒了,PcShare

#25


同求这个的解决办法

#26


我也碰到了这个问题。我认为不是SQL的问题,我把1433改为IIS的端口,结果从其他服务器也不能访问这个端口。而本机访问无论是IIS还是SQL,都是正常的。这效果就和用了防火墙,把1433给拦住了一样,但实际上我是没开任何防火墙的,系统自带的也早关了的。而且,我还测试了其他很多端口,发现只有1433不行,别的都行。

我的也是突然出现了这样的问题,系统用了蛮久了,没中过马没被黑过,但是打过很多次补丁,我认为这个问题应该是系统问题,可能是打了某个补丁后,系统自己把1433端口给堵上了。

楼主是怎么解决的,估计最后是重装系统吧?我也没找到别的办法了。

高度关注..

#2


是网络问题吧,是不是1433端口被网管封掉了?

但最的发现有2台服务器都是这种情况,同网络中其它SQL Server服务器正常,网络应该是没有问题的

我换端口访问是没有问题的,现在是想找出问题出在什么地方,因为我现在同时有2台机器都出现这种情况

#19


感觉不应该与端口有关?

#20


我感觉是中了什么针对SQL Server的病毒或木马,但诺顿查不出来

#21


我们以前也出现数据库莫名其妙的问题,与这个有点类似,
发现打了补丁后系统运行就不正常,

最后逼得没有办法,重新启动一下机器进行逐一排查,最后就好了,你也可以试一试 ,
这也是下下策了,

#22


系统莫名地创建了一个“full”用户

#23


是不是被黑了?或是成僵尸了?
卡巴斯基,杀之!

#24


中毒了,PcShare

#25


同求这个的解决办法

#26


我也碰到了这个问题。我认为不是SQL的问题,我把1433改为IIS的端口,结果从其他服务器也不能访问这个端口。而本机访问无论是IIS还是SQL,都是正常的。这效果就和用了防火墙,把1433给拦住了一样,但实际上我是没开任何防火墙的,系统自带的也早关了的。而且,我还测试了其他很多端口,发现只有1433不行,别的都行。

我的也是突然出现了这样的问题,系统用了蛮久了,没中过马没被黑过,但是打过很多次补丁,我认为这个问题应该是系统问题,可能是打了某个补丁后,系统自己把1433端口给堵上了。

楼主是怎么解决的,估计最后是重装系统吧?我也没找到别的办法了。
