Hi Aadi,

Thank you for the post.

Please perform steps below to troubleshooting:
1. Disable UAC and restart the server
2. Use local admin account to take the drive ownership
3. Boot system to safe mode to take the drive ownership
4. Try to use command Subinacl /directoriesonly C:\  /setowner=administrator to take the ownership

Here are some related article, hope it helps you.

Hi Rick Tan,

Many Thanks For your reply.

I am unable to disable UAC i think due to permission issue can't access the UAC from administrator user. 

Is there any other way to disable UAC.

Regards

Aadi.

Hi Aadi,

Local admin account has the permission to take ownership in your system. Please ensure your operations with Local admin account.
To disable UAC, boot system into safe mode, set registry key EnableLUA value to 0 under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System.

Hi Rick Tan,

Great :) its works and now some application still not working properly (like Internet Explorer) after giving full permission to local admin.

i give the permission with these commands

For Files:

takeown /f file_name /d y
icacls file_name /grant administrators:F

For Folders or Directories (will perform action recursively):

takeown /f directory_name /r /d y
icacls directory_name /grant administrators:F /t

And when i am access the network properties to changing the ip address its give me error. "An unexpected error occur" .

is there any thing that i am missing.

Thanks & Regards,

Aadi.

Hi Aadi,

Please try KB824923 to register netshell.dll and ole32.dll.
It seems your server has been broken more and I suggest you restore your system from backup if you backup it before.
