When you Setup Static Ports for Microsoft Exchange Address Book and Microsoft RPC Client Access Services and if the same Port is already used by another service which can result service start fail.
You can follow the below steps to configure the static ports,
UDP/TCP 59531-65535; set static ports
To set a static port for the RPC Client Access service on an Exchange 2010 Client Access server, you need to open the registry on the respective server and navigate to:
Here, you need to create a new key named ParametersSystem, and under this key create a REG_DWORD named TCP/IP Port. The Value for the DWORD should be the port number you want to use.
To set a static RPC port for the Exchange Address Book Service, create a new REG_SZ registry key named “RpcTcpPort” under:
1. Find whether same port used by another process by using NETSTAT command.

2. Restart Microsoft Information Store service which will release if the same port used.
3. Check which service is using that ports using NETSTAT /autob
