Am I right in assuming that if I install a new primary server into an existing ZCM zone, that it will automatically get the updates from another primary? Or would I need to send out the updates to the new primary?

I have a windows 2003 Primary server and have just installed a new SLES 11 primary server. The windows server is ZCM 10.3.3 and SLES at the moment is sitting on 10.3.0 and if I try update this server it says the content has not replicated and I should check my nearest server rules. These servers are sitting next to each other at HQ in the same subnet.

A bit confusing.
