We are running MA4.0 with one main ePO server and a distributed repository at a backup location on another subnet. We were able to set up a distributed repository on a server at the backup site as a UNC path. When trying to get the clients at the backup site to use the distributed repository instead of the master repository, ping time or subnet distance don't seem to work. When we try subnet distance, in the log it appears that the distance to each repository is the same (16) and it defaults to the master. If we try ping time, the log doesn't show any type of ping test results and the update defaults to the master.
