KM,
It depends.

When you set up replication, you have the option of assigning a synchronizarion priority. If none is set then the changes get assigned the priority of the publisher machine. If both machines in question, get assigned the same priority (either explicitly by you or automatically in the case above) then the first machine's changes will take effect. If you set different priorities then the changes from the machine with the highest priority will win.

HTH.
