Question:

R3000's are not able to synchronize with each other

Reply

In System -> Synchronization, you need to configure one server as the “source” box, and the other sever as the “target.” 
For synchronization to work, all of the servers must be at the same software version.  The current version number appears at the bottom of the “Home” window.

Make sure that the servers can communicate with each other on following TCP ports: 

26260
26262
26265
26266
26267
26268
