RightFax 9.x: How to reserve a port for RightFax services

Question

RightFax applications typically require the RightFax RPC Server Module (FaxRPC.exe) to authenticate to the RightFax server. The FaxRPC.exe uses TCP ports 1052, 1053, 10520, and 10521 to communicate with the server. If these ports are in use by another process, it can result in error messages such as:

error 1722 The RPC server is unavailable.

The RightFax DocTransport Module (RFDOCTRANS.exe) will also require TCP port 1062 and 10062 when receiving fax schedule requests from the Server modules and also for LCR routing between ENT servers. The RightFax Remoting Module (Captaris.RightFax.RemotingService.exe) will require ports 34987 and 34988 for the .Net Remoting API for RightFax.

If the required ports are grabbed by a different process before the RightFax services can get to them, it can result it major functionality loss. For this reason, you may want to reserve a range of ports between 1052 - 1062, 10520 - 10521, 10062, and 34987 - 34988 so that the RightFax services can work properly.
