RDP 證書過期 （Windows 2008 R2），怎麼辦？

最近一臺windows 2008 R2服務器不能遠程桌面登錄，並提示“Remote Desktop cannot connect to the remote computer because the authentication certificate received from the remote computer is expired or invalid。”

參考http://rivald.blogspot.com/2011/06/replacing-self-signed-remote-desktop.html，立馬就能登錄了。步驟摘錄如下，英文簡單就不翻譯了：

 1. open mmc.exe (Microsoft Management Console)

 2. add the add-in - certificates (for the computer account) (and select local computer)

 3. navigate to the remote desktop folder -> certificates
 4. delete the certificate for the name of the server and close the mmc instance
 5. Go to: administrative tools -> remote desktop services -> remote desktop session host configuration

 6. Select the instance in the main window - rdp -tcp -> right click and select properties
 7. on the window that pops up, select default

其實，碰到這個現象，還是可以用mstsc /admin 命令遠程登入的。
