i have a problem after installing windows updates my server windows 2008 R2 enterprise reboots when displaying "Preparing to configure windows, Do not turn off your computer" i really hate to rebuild this server and i don't have a recent backup for it any ideas ?

Hello, did it start after the reboot or not, you didn't mention the current state of the server? Are you able to use F8 and safe mode booting?Best regards Meinolf Weber Disclaimer: This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.

Hello, it seems that you are lost and without a backup.... I would contact Microsoft support for help.Best regards Meinolf Weber Disclaimer: This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.

Hi, Please unplug all external devices like external hard drive, USB drive, etc, and restart the computer to test again. Meanwhile, is this server a Domain controller? If so, is there any other DC in the domain? Regards, Bruce

no external drives attached to the server and the server is not a domain controller is an application server with IIS and SQL 2008 x64
