How to Remove an Orphaned Domain Controller (2008r2+)

If you ever lose a DC or one gets deleted before it is properly demoted using DCpromo

… or maybe you tried DCpromo but it wasn’t able to clean up AD on your other DC’s.

As of Windows 2008r2, if you right click and delete a computer object that happens to be a domain controller you will be prompted with the message shown below. Just tick off the checkbox and away you go; now you don’t have to go into ADSI Edit and clean out the old server, ADUC does it for you!! 🙂

Don’t forget though… you still have to go into DNS and clean out all the Name Servers and other entries pointing to your old (now dead) DC.

Admittedly, I’m no AD expert…
Did I miss anything? Let me know in the comments.

How to Mount an NFS Share to Windows Server

…It’s not all that difficult. Who knew (shrug).

this should work for Windows 2008r2 and later

  1. Install the File Services Role

  2. If the role is already installed (like it was for me), you just need to enable the NFS Service for that role:

  3. Mount drive just like any other mapped drive:

  4. You will now see the drive mounted under Computer:

    Note: You can now use the mount and umount commands to manipulate NFS mounts through command line:
