After your install SP1 on Windows 2008 R2 SP1, you could encounter problems with RDP after reboot. This happens if http://support.microsoft.com/kb/2667402 is already installed.
Fix:uninstall http://support.microsoft.com/kb/2667402 before installing sp1j
If you are already have installed SP1 with KB2667402 already installed you must uninstall KB2667402 and then it. Can uninstall it remotely with following command:
Wmic/node:<server> process Call create "PowerShell Wusa/uninstall/kb:2667402/quiet/forcerestart"
After you update Windows 2008 R2 SP1 you may find that RDP is not working properly after restarting (login not in)-this may be because kb2667402 has been installed (http://support.microsoft.com/kb/ 2667402)
Uninstall this update package so that the RDP will be successfully logged on again, but if the remote server I can not direct the operation of the machine then how to do?
Don't worry, use the following remote Access command to achieve:
Wmic/node:<server> process Call create "PowerShell Wusa/uninstall/kb:2667402/quiet/forcerestart"
The original text to the command does not give user name password parameters, 99.999999% of the server is required username password to log in, so you can try the following command
wmic/node:< server address >/user:< username >/password:< Password > Process call create "PowerShell wusa/uninstall/kb : 2667402/quiet/forcerestart "
