问题是这样的,我有几个网站,
WEB程序是用net开发的,数据库是用Sqlserver2000数据库的.
WEB程序是放在杭州电信,数据库是架在上海电信的,然后,两个是用IP,帐户和密码,这样远程相联的.

这样运行了大概有三个月了,都没有出现什么问题,因为是新站人气不是很高,现在因为大概所有站加起来流量大概有一天有一万IP左右,最新老是高峰期出现NET与数据库超时,连不上.

现在我解决的方法就是,上服务器,重启SQLserver服务器,有的时候,重启了也不行,要先停止,再重启,这样反复好多次才行.

因为,这种情况,一天至少有二三十次,所以我想求大家给一个解决方法,帮忙分析一下问题也可以,提供思路也可以,在此谢谢大家了.

回楼上这位大哥，我用了你的存储，我把结果发上来，执行时间大概在33秒，注，这个时候的结果，是网站可以正常访问的，等一下，我把网站不能正常访问的也发上来．

还是一个明显的情况,
就是,当我网站打不开时,出现超时的时候,我去服务器上打开SQL的时候,SQL企业管理器,就变得非常非常的慢,就是卡死一样,基本上就是打不开,但是,我把SQL服务器停止后,又重新启动一下,打开SQL企业管理器就变得正常了.这样,我再去连接网站,就可台正常访问了,但是也坚持不了几分钟.

这样,应该不是带宽问题吧.

-------------------------------------------------------------------------------------
如果存在大量的进程没有释放，而实际上Web页面的所有连接已经关闭，则说明程序存在问题

查询分析器中执行系统SP：

exec sp_who

或

sp_who

我只是用了普通的连接方法,
请问楼上,如何执行sp_who,具体如何查看资源释放

楼主的程序中有没有使用连接池？

在查询分析器中执行SP_WHO，判断是那些进程占用了系统资源没有释放。

如果在高峰时段经常出现，且较有规律，应该就是带宽问题。

或者你的程序的实现方式有待改进。

首先多谢你们回复,带宽都是电信机房的,100M共用的,带宽应该不是问题吧,有没有办法如何看SQL资源用在哪里,

1.可能是带宽的问题
2.可能是服务器的配置相对较低

自己找一个测试环境，运行WEB程序打开不同的页面，并在查询分析器中检查进程的状况。

带宽不够？
