Our database is in SQL Server 2008 R2 and we are running DB at ver. 10.1 and clients at 10.1 and 10.3.1. I created M:N relationship classes for the majority of feature classes in a dataset, but the permissions on them were not changed to those of the dataset and there is no way I can see from Arc (outside of SQL Server Management Studio to set those privileges, so the feature classes did not work at all in REST Services or in ArcMap. Should I re-permission the dataset or is there some other method I am missing. BTW...we did reset permissions to the related tables that cannot reside in a dataset just fine.
