在过去的三个月左右的时间里，我遇到了随机错误，无法绑定(bind)在本地开发工作站上运行Identity Server的特定端口。起初我以为是我的机器坏了，所以我重新设置了所有内容，这已经解决了2个月了，现在又回来了。
同时，其他开发人员也遇到了同样的问题。我们所有遇到此问题的人都在运行Windows 10，但并非每个使用Windows 10的人都遇到该问题。
用shutdown /s /f /t 0关闭后重新启动Windows是唯一再次打开该端口的可靠解决方案。在我正常重启后(由于Windows更新或类似原因)，问题再次出现，我需要使用该命令关闭Windows。
我写了一个小的f＃脚本来测试哪些端口受到影响。我得到的确切错误消息是
当我寻找它时，建议的解决方案可以在哪里重新启动计算机，但这似乎更像是一种解决方法，而不是真正的解决方案。我还找到了https://stackoverflow.com/a/10461978/621366-但netstat -o并未列出端口，TCPView工具也未列出。我们所有人都非常确定该端口没有被任何东西占用。我还尝试在管理员控制台中运行netstat，并在Windows的bash中运行类似的命令，但找不到任何内容。我什至无法通过telnet连接到该端口，它说什么也没有监听该端口。
这些端口例如是:
除了Windows 10的默认工具外，我们没有人修改Windows防火墙上的任何内容或安装任何其他防病毒工具。因此，所有内容均应使用默认值。而且它在第一次破裂前也能正常工作约10个月，之后再破裂2个月。在这两种情况下，在安装某些Windows更新之后。上次是BIOS更新(可能是由于故障/幽灵问题？)。
此外，尝试在防火墙上显式打开端口也无济于事。
根据此答案，https://stackoverflow.com/a/23982901/621366 TCPView和netstat不应丢失任何已占用的端口，但是即使启用了TCPView中未连接的端点的显示，在尝试绑定(bind)它们时，也看不到我拒绝获得许可的任何端口。这是占用端口的屏幕(我标记了权限拒绝端口组之前或之后的边界占用端口)
更新:
我注意到，总是有160或180个(确切数量)的端口被拒绝，其权限被拒绝在40,000+范围内，这对我来说似乎是奇怪的巧合，所以显然有意在占用这些端口，但是那又是什么呢？我似乎无法在Windows事件日志中找到任何内容(尽管我不知道确切查找什么内容)，而且这些端口都没有显示任何防火墙规则。同样关闭Windows的docker并没有什么区别，当一位同事提到对他们来说足以重启Windows的docker(在UI中转到Reset-> Restart)，现在对我来说，甚至使用shutdown命令重启不再工作了。
更新2:

我本来想打开的端口是
49786，但是我的小型测试算法拒绝了许可报告的端口数量，但是在检查netstat时却没有分配该端口，这使我感到困惑更新3:
现在，仅运行
shutdown /s /f /t 0不再起作用，我发现了另一个变通方法，它似乎在https://social.technet.microsoft.com/Forums/windows/en-US/e0cc1b3e-2c63-451a-abc8-8e1e66a23287/an-attempt-was-made-to-access-a-socket-in-a-way-forbidden-by-its-access-permissions?forum=w7itpronetworking中相当可靠地工作-netsh int ip reset并重新启动计算机(正常的Windows 10重新启动就足够了)，并且端口在下次启动时始终可用到目前为止(但仅3次尝试)更新4:
评论摘要:
最佳答案
原因是Hyper-V接管了这些端口，为防止发生这种情况，请执行以下操作:
dism.exe /Online /Disable-Feature:Microsoft-Hyper-V(必须重新启动)netsh int ipv4 add excludedportrange protocol=tcp startport=<your port> numberofports=1 dism.exe /Online /Enable-Feature:Microsoft-Hyper-V /All 原始解决方案是here。
如果之后您仍然无法绑定(bind)到端口，请执行以下操作:
IPv4的
netsh http add iplisten 0.0.0.0 netsh http add iplisten :: 更多信息是here。
关于windows - 由于权限被拒绝，因此无法绑定(bind)到某些端口，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/48478869/
