"An error occurred while loading the default Password Replication Policy" (RODC)
I was called to troubleshoot an Installation of a RODC server at one of my customers place last 3 days back. I beleive it was really a very good troubleshoot which I want to share with you guys. The scenario was as follows.
The Customer was having Windows 2008 Writable Domain Controllers and some Windows 2003 ADC'S. So before introducing RODC in the environment we full filled all the requirements like running ADPREP /rodc was ran so schema is extended and all other things which Microsfot recommends to Do from the following guide http://technet.microsoft.com/en-us/library/cc731243(WS.10).aspx inspite of that Whenever we ran DCPROMO and checked RODC and hit next a failure message poped up stating "An error occurred while loading the default Password Replication Policy. The error was: The network address is invalid.".
Solution:
My customers missed to precreate the RODC account so that there is Password Replication Policy to find. Once that was done the promotion went on through using the dcpromo /UseExistingAccount:Attach command.
