[CRM] Unable to obtain DNS hostname of Active Directory domain controller

In CRM 4 and CRM 2011, are you trying to create an organisation, import an organisation or register some plugins and you are getting the following error:

[…] Unable to obtain DNS hostname of Active Directory domain controller […]

Weird, isn’t it?

In my case I was trying to register some plugins and I got that messages from the CRM traces.

Finally, I found the problem and the solution:


  • Active Directory contains many domain controllers.
  • You have insufficient permissions to query all domain controllers.


  • Install last rollup (I got 17 and it works fine)
  • Add the entry PreferredDc in HKLM\Software\Microsoft\MSCRM with the closest domain controller (run this command >echo %logonserver% in your CRM server)
