windows - 如何检测 Windows 服务器在重启后是否可用？

Question

我想使用任务计划程序或类似工具自动执行 Windows 2000+ 服务器重启过程，以远程重启服务器并等待它恢复。我可以发出 shutdown 或 psshutdown 来远程重启，但我想要比 sleep 更好的东西来等待它回来。我需要验证它是否在 n 分钟内重新联机，否则会引发错误。

通过“重新上线”，我想验证的不仅仅是它可以被 ping 通，还可能是它的 RFC 服务正在响应或其他一些确定的生命体征。

我更喜欢 NT 脚本方法，但我不排除编写自定义工具来执行此操作。

有什么想法吗？

经过一段时间的研究，我想到了以下 VBScript。欢迎评论/改进。

' Remotely reboot a server and
' wait for server to come back up.

' Usage:  cscript /nologo /E:VBScript RebootWait.vbs <Server Name>
