It seams that replication between the main DC server and one of the DS is not working. The DS is connected to the central location through a VPN.

is empty!

How can I discover if there is a communication problem?

As far as I understand, the patches are replicated from the main server (or directly from Internet - ManageEngine DC site?) to distribution server, and software packages are replicated only if HTTP store is used? What about using DFS (Distributed file system) as a way for SW packages replication?

It seams there is a lack of Advanced tutorials for DC deployment, which would cover this and similar topics.
