Why file permissions issue?

This is using a Windows 7 desktop. I just join this desktop to a MS Windows 2008 AD domain, and the user profile migrated as well. The user is the original user, so this user profile was in C:\Users\Tait123, and now this profile is used by a domain user named JF\andre.tait. There are about 600 GB files and folders within this profile.

The user can log on to the desktop without problem. However, when he double-click to open any folder/file (or shortcut) on the desktop, the following error message prompts:

    Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item.

However, the user was given the "full control" of all the files and folders. What went wrong?

Thanks in advance.

Sounds like you only have the same name, not the same SID anymore.. run as domain admin takeown and set the user as owner for folders and files.

Hi ste5an,

Already see the user as the owner, and even granted this user with full control on all files and folders.

Hi all,

At the end, I move all the files and folders to a usb hdd, create a new profile for the user, and then move those file and folders back to this new user profile.

Above solution works.
