今天特奇怪，好好的服务器运行防火墙时出现“由于不可识别问题 windows无法显示防火墙”，查了相关资料原来是由 SharedAccess.reg 文件丢失或损坏。 SharedAccess.reg 文件代表了 Windows 防火墙服务。
解决方案：
- 将以下文本复制到记事本, 然后再保存文件作为 Sharedaccess.reg：

- 重新启动 Windows。
- 单击 开始 ， 单击 运行 , 类型 cmd然后单击 确定 。
- 【LGF注：可能会丢失防火墙设置吧】在命令提示符, 键入以下命令, 然后按 ENTER 键：Netsh firewall reset
- 单击 开始 ， 单击 运行 , 类型 firewall.cpl然后单击 确定 。
- 配置与要使用 Windows 防火墙设置
