I have an clustered exchanger server with PDC and BDC in the same domain. Now I've followed this
(dual server mode)
to setup RPC over https which worked great inside of the local network. However, when I move the computer out of the network, outlook wouldn't connect to the exchange.
1) when using outlook within the network, outlook /rpcdiag shows that it connects to exchange and pdc (for directory service), but the pdc is strictly internal, so does that mean I need to open the pdc to public ? or can I use exchange for authentication?
2) I also have BDC as a backup (it's also a GC), but in the rpc over http guide, there mentioned only one dc, could I just put BDC in the registry as well?
