[Samba] Replication taking time

No great technique. We have two Virtual machines with RSAT connected two 
domain controllers of the same location, same network segment. When we 
create an object in say OU in one of the domain controllers, we expect 
the object to be replicated immediately to the other. It appears in the 
second server after about 3 - 4 minutes and continuous refresh. By the 
same time it appears in the DC in the same network segment, it is 
visible in the other two DCs in a different location.

We are also monitoring the network load, throughput constantly and find 
there is hardly any network load.


Thanks & Regards,
