According to our gurus:

The limit is in AD, which has a sizelimit of 2000 by default.  There are
two ways around this:
1) Go into AD and set the sizelimit for the sync user to be greater than
the number of entries.
2) Have DS winsync use simple paged results - this is a code change on
our side and we are tracking it for one of the upcoming releases
