Yes sure, I can do the same thing through remote desktop access..
I've made now one attempt with interesting result:
I added an anditional site(Server2-S2) from my primary server(S1). After replication, in console, the folder with managed clients(S1) has been replaced with the folder(clients managed on S2) from S2. S1 clients disappeared. On another site, S2 is managing the same clients like before-nothing changed, nor clients from S1 has been added here. I thought that after replication I'll be able to see clients in both consoles in both sites.. What went wrong??
