I have so far been unsuccesful in getting ERAS and ERAC to work on the same machine (My Windows Home Server server). Thus they would connect via localhost, but I can not see the clients in ERAC and connection often fails. I will post logs and stuff if requested, but maybe there is someone who knows a common issue with this? On different machines ERAC connects nicely to the server where ERAS is installed. I seriously doubt this may be due to any port issues. All machines have ESS 4 installed and in learning/interactive mode.
