Clarification. &nbsp;We have two RUS's &nbsp;the Enterprise COnfiguration, and then the domain related one in the second position. &nbsp;The Enterprise one seems to resolve just fine, but the second one does not. &nbsp;These were created before me. &nbsp;Are two of them necessary? &nbsp;Again I don't want to break more than I fix. &nbsp;
