IMC服务器重启后提示授权无效

IMC登陆页面提示license无效，之前是正常使用的

1、经确认IMC安装在物理服务器上，未做过迁移，服务器未重启过，未修改过网卡等硬件参数

2、检查license文件正常

3、收集前台日志（路径：iMC安装目录/client/log/imcforeground）查看，发现报错：mac地址获取硬盘序列号不匹配

 2021-07-16 18:17:28 [ERROR] [http-nio-8080-exec-14] [com.imc.license.entity.LicenseBean::checkLicenseValid] Hardware Info is invalid!

4、检查服务配置发现windows开启了uac功能,尝试关闭UAC

运行命令行：gpedit.msc,将级别改为不提示直接提升

5、备份license文件后删除license文件，然后重启IMC重新注册，问题解决。

关闭windows UAC功能，重新注册
