How to connect to Microsoft Dynamics Rms 2.0 Running sql2008r2?
You're going to need SQL Server 2005 backwards compatibility components installed at the client PC for that version of RMS to connect to any SQL Server newer than 2005 if I recall correctly.  Good luck finding a download link. Microsoft seems to have nuked all of them from what I can tell.  If you are taking over support of a system, search for an msi installer package named &quot;SQLServer2005_BC_x64.msi&quot; or x86. You probably want x64 on any newer clients though.  Hopefully you have a local copy already in an install folder somewhere assuming the previous RMS clients needed it to connect to the same DB Server.
Hope this helps.
