In some cases it’s good to replicate a virtual machine in and outside a clustered system.
I tried this the very first time but after setting up the replication broker role in the failover cluster manager I got an error.

After researching a while whats going on I got a solution.
The Cluster Role couldn’t write a computer object.
Usually you set up an OU where the Hyper-V Servers belongs to and there is the Cluster Role (actually a computer account created during the installation) as well.
Anyway…

The Cluster (machine account) has to get writable access to this OU and after that… The Replica Broker is working. 🙂
