远程终端安装Windows Server 2003 SP2 x64后出现提示0x8007007f，许可证错误

　　一台区部的Windows Server 2003 R2 64位版服务器，通过远程终端安装Windows Server 2003 SP2补丁后，注销后登录，出现提示“一个问题阻止 Windows 准确地检查此计算机的许可证。 错误代码: 0x8007007f”，确定后就自动注销了，再次连接问题依然，郁闷了......
　　查过资料未发现相关问题，Microsoft Support Site也没有相关KB，估计SP2比较新，无奈只好请求区部同事帮助，还好直接在服务器上还是可以登录，进入后卸载SP2症状消失，于是请同事帮助安装，直接在服务器上，相同的SP2文件又安装成功了，经理BS了一下我 ：） 再次郁闷了......
　　操作系统是正版的，事件日志有以下错误提示：
　　事件来源: Windows Product Activation
事件 ID: 1000
用户:  N/A
描述:
向导在检查当前 Windows 产品许可证时发生错误。错误代码: 8: 0x8007007f
　　在网上的资料不多，终于看到一个国外仁兄和我一样的遭遇，引文如下，继续关注此问题：

　　I have several 64bit Windows Servers 2003 servers which were updated with SP2 last night and they were rebooted by clicking the "reboot now" button in the pop-up window which you get if you don't reboot immediately after installation.
　　After a time, attempts to RDP in to the system failed and logging in locally got me a nice 0x8007007f error with some language to the effect that something bad had happened to prevent the system from validating the license for the server.
　　On one server I fixed it by hard power cycling the server and removing SP2.
　　On a different server, I took more time doing it and I noticed that the server never actually rebooted. The console just brought back the login prompt after a time as if it HAD rebooted. Doing a hard reboot
of the server allowed things to come back up just fine.
　　The point of my posting is to let others know that if they have this problem that they should first hard power cycle their system and see if that fixes the problem -- don't be fooled by the phantom reboot.
