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 Install vSphere Client on a Windows Domain Controller

As of vSphere 5.5, installing the VIC on a DC errors out.

I read that it was done purposefully, to keep people from installing software on DC’s… which, makes sense for most situations – not so much for others. For instance, a small shop where one might need to utilize a DC for many other functions.


Anyway, to get to the meat of this article; in order to get the VIC to install you need to launch it from the command line with option /V.

  1. Make sure to run command prompt as admin: img2

  2. Then run the following command: VMware-viclient-5.5.exe /VSKIP_OS_CHECKS="1"

There you have it… you can now run through the install like usual. 🙂
