When trying to rename any folder we are getting error - action cannot be completed because folder or file in it is open by another program

Hi,

    Recently we are seeing this error - whenever we rename any folder we are getting error - action cannot be completed because folder or file in it is open by another program. If I create a new folder, I can rename it. But any existing folder is giving this error when we rename it. Happens with all folder. Tried rebooting the OES server. Still the error is seen.

Thanks in advance for any help
