我正在開發一個web應用程序，運行IIS Express時，出現如下錯誤：
“Unable to connect to the configured development Web server. Failed to register URL http://localhost :21021/ for site “sandbox” application “/”. Error description: Access is denied. (0x80070005)”
解決方法：
running this command in Powershell showed the culprit:
netsh http show urlacl
Reserved URL : http://10.208.41.127:21021/
netsh http delete urlacl http://10.208.41.127:21021/
已成功刪除 URL 保留項
