Hey y’all, Mark here again with a  quick announcement. Our brothers in arms at AskDS have just posted something that you need to be made aware of if you have a mix of 2003 DCs and 2012 R2 DCs in your environment. Head over for all the details and we’ll keep you updated with any info once we get it.

Update 8-28-14 The KB 2989971 has been posted to address this issue. See the AskDS post for any questions.
