Can someone or anybody here have an idea with error title above. We have nstalled 3 Exchange server 2013 CU23 in the environment. When we tried accessing other virtual directories of other exchange servers and make some changes the error always prompt. Cannot connect to the remote procedure call service on the server named EXCH2013. erify that a valid computer name was used and the Microsoft Exchange Service host service is started.
For Isolation :
We have check the firewall side and make changes from restricted to any to any the error disappeared but this is not the standard on the network firewall, and we need to specify the specific ports which needed for this.
Defined firewall port for exchange 2013 :
TCP port 25 – SMTP
TCP port 80 – HTTP for Outlook Web Access
TCP port 443 – SSL secured HTTP for Outlook Web Access (HTTPS)
