Nothing.

The switch to native mode from mixed mode ONLY affects replication between
the Win 2k DC and *any* NT 4.0 BDCs in the SAME domain.

It does not affect:
Member servers in the same domain
Clients in the same domain
Trusts with Win 2k domain
Trusts with NT 4.0 domains
DCs, member servers, clients in trusted Win 2k or NT 4.0 domains
Clients, member servers, DCs in child domains
Clients, member servers, DCs, in parent domains
