"Access Is Denied" in Windows Explorer when trying to read contents of External USB Backup disk

    Question

  • I would like to view the contents of a backup disk connected to my SBS 2011 server.  Backups are completing successfully and I want to use cloud based backup to store the backup files in the cloud.

    I've opened Disk Management and assigned a drive letter (K:) to my backup disk "Backup Disk 1".  When i try to view the contents in Windows Explorer I get "K:/ is not accessible... Access is denied".

    I am able to view the properties of the disk in Disk Managment and I am able to view the directory structure of the K: drive using an elevated command prompt (i.e. k:, cd\windowsimagebackup, etc.). It's just Windows Explorer where I am having the problem.

    I have checked the permissions and ownership of the and the Domain Admin has full control (Im logged on as a domain administrator).  When I try to change ownership, it errors again with "Access is Denied".

    I've been able to do this on other SBS 2011 systems.  It's this system that is giving me the problem. 

    Any ideas or things I might try? 

    Thanks.

  • Yes, I ran the command line tool as follows; takeown /f k:\*.* /r.  The reponse was "success" for all the directories.  However, when I try to access the K: drive in Windows Explorer I still get the Access Is Denied message.

  • I've tried takeown both using Windows Explorer and at a Command prompt and still get the access denied message in WINDOWS EXPLORER.   I can transverse the directory and drives from a command prompt just fine.  These articles are nothing more than "hey try this", "hey try that".  Further, one of the articles suggests starting the computer in safe mode.  As mentioned in my initial post, this is a PRODUCTION SBS 2011 server and cannot be started in safe mode whenever I feel like it. 

    I'm disappointed that this is all Microsoft suggests. I would expect much more from a company that claims to be world-class.  I would suggest letting someone who knows about Windows Server 2008 R2 and NTFS security settings answer as they may be more qualified to provide an answer instead of just suggesting reading more forum posts. 

    If no one has an answer, I'll open a support ticket with Microsoft PSS.  I don't have the time to read or "try" different things suggested in other forum posts.

  • Andy,

    Do you have any other recommendations?  Do you know how I might escalate this to a support engineer who is familar with this issue and and provide some troubleshooting steps?  I don't want to read through a bunch of blog posts of other people's troubleshooting.

  • I fixed this problem by setting User Account Control to "never notify".
