Merge replication question

We are using merge replication with 600 users over a nationwide wan/lan
network. For the most part it works, but occasionally some changes will not
be merged to the agent. All changes make it to the server, but when users
sync the changes do not come down to them. Someitmes if they do multiple
syncs in succession they will make it but other times not. We do a snapshot
of the database nightly that is used by new users to get the initial
database. We have noticed on one user where they installed the snapshot but
did not immediately sync afterwards (we instruct them to so so that they
will get any changes since the snapsot was created). They sync'ed the next
day after a new snapshot was created.. Changes in the database from the
snapshot downloaded one day to the creation of the new sanpshot will not
sync to the database. Changes after the second snapsot is created will
sync. It appears the the client DB thinks it has the records and does not
need to get them. Any thoughts?
Can you run validation on a couple of your subscribers and let us know the
results? Are you using filtering or does each subscriber receive the same
set of data? What build of SQL Server are your subscribers and publishers
on?

|||There is no filtering, all users get all data. We are using SQLServer 2000.
We confirmed today that the issue is the data lost between the creation of
the snapshots. When a new snapshot is created, data that is the new
snapshot but not in the snapshot downloaded will not syncronize if a sync
was not performed immediately after the snapshot is loaded. Any settings
that would cause this behavior?
