Probably the well known Windows bug:

Your problem with assigning drive letters was reported sometimes, but this is not Daemon issue. Drive letters for CDROM are assigned by Windows itself (not Daemon) and this is in fact bug in mount point manager, which assigns new letter over existing network mapping.
