we are trying to add a DC (2k3 r2) to our existing domain which only contains one machine at present – a 2k3 exchange server running RPC over HTTPS
we can join the domain fine on the new server.
when dcpromo is run to upgrade to a DC we get the error “RPC server not available”
we are led to believe this is because the RPC over HTTPS on the exchange server is making RPC unavailable for the DCpromo process some how…
can anyone enlighten us on what the issue might be and how we might get around it?
