日志中也很奇怪，服务器会自己访问http://192.168.2.166/news/LocalNews.aspx/SearchTitle.aspx这个页面

只有把服务重启后才正常，请帮忙分析下这是什么原因
[解决办法]
请你注意这条记录
TCP 192.168.2.166:50274 192.168.2.166:80 FIN_WAIT_2 2036
2036指的就是PID，也就是说在连接你IIS的那个进程。你查一下这个是什么进程就可以了。同时我发现这个进程还在连接数据库呢。
另外，你的站点访问慢不一定跟IIS连自己有关系。
[解决办法]
应该是在访问数据库后没有关闭连接，造成资源占用越来越多，就慢了
在访问完数据库后要关闭数据库连接
