Can't start Apache on Windows Server 2008 R2
提问by Tom
I got the following error when trying to start apache:
尝试启动 apache 时出现以下错误：
(OS 10013)An attempt was made to access a socket in a way forbidden by its access permissions. : make_sock: could not bind to address 0.0.0.0:80 no listening sockets available, shutting down. Unable to open logs
(OS 10013) 尝试以访问权限禁止的方式访问套接字。: make_sock: 无法绑定到地址 0.0.0.0:80 没有可用的侦听套接字，正在关闭。无法打开日志
I could start it before. I guess after I enabled feature of windows '.NET Framework 3.5'. now I can't start it properly. I have checked the port:
我以前可以启动它。我想在我启用了 windows '.NET Framework 3.5' 的功能之后。现在我无法正确启动它。我检查了端口：
netstat -aon|findstr "80"
TCP 0.0.0.0:80 0.0.0.0:0 LISTENING 4
TCP [::]:80 [::]:0 LISTENING 4
tasklist|findstr "4"
System Idle Process 0 Services 0 24 K
System 4 Services 0 304 K
How to resolve this?
如何解决这个问题？

After searching for a solution online, I saw people blaming MS SQL reporting services, all MS SQL services, Windows Remote Management service etc. But one post had a helpful diagnostic command that allowed to to track the listening service to w3svc.
在网上搜索解决方案后，我看到人们指责 MS SQL 报告服务、所有 MS SQL 服务、Windows 远程管理服务等。但有一篇文章有一个有用的诊断命令，可以跟踪 w3svc 的侦听服务。

e:\DIR>netsh http show servicestate
Snapshot of HTTP service state (Server Session View):

I could see the services running under the detected PID using the tasklist command.
我可以使用 tasklist 命令查看在检测到的 PID 下运行的服务。
e:\DIR>tasklist /svc

I could inquire configuration details of these services.
我可以查询这些服务的配置细节。

I could not stop them from command line running as a regular user.
我无法阻止他们以普通用户身份运行命令行。

The following services are dependent on the Windows Process Activation Service service.
Stopping the Windows Process Activation Service service will also stop these services.
World Wide Web Publishing Service
Net.Tcp Listener Adapter
Net.Pipe Listener Adapter
Do you want to continue this operation? (Y/N) [N]: y
System error 5 has occurred.
Access is denied.
Then I stopped World Wide Web Publishing Service through the Services GUI, services.msc. I also changed the startup type for this service to Manual. No service listened to TCP port 80 after that.
然后我通过服务 GUI 停止了万维网发布服务，services.msc. 我还将此服务的启动类型更改为手动。之后没有服务侦听 TCP 端口 80。

Perhaps you've hit the TCP time-wait state? http://msdn.microsoft.com/en-us/library/ms819739.aspx
也许您已经达到 TCP 时间等待状态？http://msdn.microsoft.com/en-us/library/ms819739.aspx
"TIME-WAIT makes certain that enough time has passed to ensure that any TCP segments that might have been misrouted or delayed are not delivered unexpectedly to a new, unrelated application with the same connection settings. RFC 793: Transmission Control Protocol DARPA Internet Program Protocol Specification specifies the length of time that a socket pair should not be reused as two maximum segment lifetimes (MSL), or four minutes. This time period is the default setting for Windows Server 2003 TCP/IP."
“TIME-WAIT 确保已经过去了足够的时间，以确保任何可能被错误路由或延迟的 TCP 段不会意外地传送到具有相同连接设置的新的、不相关的应用程序。RFC 793：传输控制协议 DARPA 互联网程序协议规范指定了一个套接字对不应作为两个最大段生存期 (MSL) 或四分钟重复使用的时间长度。此时间段是 Windows Server 2003 TCP/IP 的默认设置。
Server applications often use the SO_REUSEADDRsocket-option so they can be quickly restarted, but perhaps your build of Apache doesn't?
服务器应用程序通常使用SO_REUSEADDR套接字选项，因此它们可以快速重新启动，但也许您的 Apache 构建没有？
You'll know if it 'just works' after four minutes. :)
四分钟后你就会知道它是否“有效”。:)
