apache遇到的两个问题 Disabled use of AcceptEx() WinSock2 API错误 [warn] (OS 64)指定的网络名不再可用。 : winnt_accept: Asynchronous AcceptEx failed.

突然网站就不动了，看了下日志：

apache遇到的两个问题：

1.[warn] (OS 64)指定的网络名不再可用。 : winnt_accept: Asynchronous AcceptEx failed.
解决：
在 httpd.conf 文件中去掉注释#
Include conf/extra/httpd-mpm.conf
修改\ Apache2.2\conf\extra
下的httpd-mpm.conf
`# prefork MPM

StartServers: number of server processes to start

MinSpareServers: minimum number of server processes which are kept spare

MaxSpareServers: maximum number of server processes which are kept spare

MaxClients: maximum number of server processes allowed to start

MaxRequestsPerChild: maximum number of requests a server process serves

ServerLimit 3000
StartServers 100
MinSpareServers 100
MaxSpareServers 200
MaxClients 2500
MaxRequestsPerChild 0
或者：在httpd.conf 中加入以下配置#mpm

Win32DisableAcceptEx
EnableMMAP Off
EnableSendfile Off
ThreadsPerChild 1800
MaxRequestsPerChild 0
`

解决网站访问变慢，log中出现指定的网络名不再可用的错误，似乎日志里又出了

问题二：
2.Disabled use of AcceptEx() WinSock2 API notice

`The Apache service named reported the following error:

[Wed Mar 18 17:18:41 2015] [notice] Disabled use of AcceptEx() WinSock2 API `

网上搜了一下，这个问题是由于WinSock出错导致的，可以通过命令重置WinSock得以解决：

netsh winsock reset

然后重启Apache即可。
