I am currently in the process of standing up a new Windows 2012 Domain and running Exchange 2010 and will be running a number of DAGs. I know with Windows 2012 that when setting up the DAG you need to create the CNO object manually and then disable the CNO. I seem to be having issues when the CNO is disabled in that it will break the DAG.
However when I enable the CNO the DAG will work.
Unfortunately as I am setting this up on a in a test lab that has no internet access, I cannot provide any screenshots of the exact error.
But I will endeavour to type the text of the error when I get to the next DAG. If anyone has experienced a similar issue and has been able to resolve it let me know as it would be greatly appreciated.
