Hi!

Please do the following:

Step#1 - Export CBS hive

• Click on the Start button and in the search box, type regedit
• When you see regedit on the list, right-click on it and select Run as administrator.
• When regedit opens, using the left pane, navigate to the following registry key and select it by clicking on it once.
  
  HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Component Based Servicing
• Once selected, click File > Export....
• Change the Save as type: to Registry Hive Files (.).
• Name this file ComponentBasedServicing (with no file extension) and save it to your Desktop.
• Right-click on the saved file and choose Send To -> Compressed (zipped) Folder.
• Attach the .ZIP file to your next post.
• If the file is too large to upload here, upload to Dropbox or OneDrive or SendSpace and just provide the link here.

Unfortunately, your registry is corrupt beyond repair. Your only option is to do an In-Place Upgrade.

Really?
Oh god, this is the unique DC. This happen just because i updated it. Have a chance for me to find the update corrupted and delete it from the registry? I think the netframework caused it.

Thanks softwaremaniac

No, it didn't. Your hive must have been corrupt before that, because it has literally a few keys when it's supposed to have hundreds if not thousands. As the hive is unique for every system, there's no chance of repair.

If it was a corrupt update, I'd root it out in a second.

If you have an earlier backup, we may be able to do something...

Sorry for the delay to answer you.
This server is the only one on the network and has less than 2 weeks, I needed to install windows server backup and then came across this problem, which I suspected was some update days before. So this server has no backup, but already has a structure of gpo, AD DNS and now I do not know what to do, since you told me that the only solution is to do an in-place upgrade. I am seeing some tool to back up the AD structure so do the procedure and not risk losing everything, would you have any tips?

Thanks for helping me softwaremaniac.

Unfortunately, I do not have any tips as I have no experience in backing up the AD. There is a discussion available here, but like I said, my AD experience is very limited and really am not sure.
