Are you deploying MDS Runtime applications at all? If no, I would suggest that you leave it alone and save your precious time for other BES issues like message flow, lookup etc. MDS-IS is not the MDS-CS that is associated with BlackBerry Browser browsing for Intranet/Internet Site.
RIM is ending support for MDS Runtime and MDS Studio this year. For more information, see linke that I shared:-
