Configuring Static Ports on Exchange SP1 CAS Servers

Before we start with creating Virtual services, it is advised to configure static ports on exchange 2010 cas servers.

Here I am going to explain how you can do on Exchange 2010 SP1.

Note: The following registry changes need to be done on all of the CAS servers. Once changes are made, restart the RPC Client Access Service for the changes to be applied.

• I am going to use 55000 for Exchange RPC and 55001 for Exchange Address Book. It is recommended to use the same static port on all the servers with in the AD Site.

Exchange 2010 Sp1 RPC:

Log on to the Exchange 2010 SP1 CAS server and open the registry and Navigate to the following:

HKEY_LOCAL_Machine\System\CurrentControlSet\Services\MSExchangeRPC.

Right-Click MSExchangeRPC, Select New Key. Type the name as ParameterSystem.

Select Parametersystem, and on the right-hand side, create a REG_DWORD named TCP/IP Port and put 50000 as Decimal Value.

Exchange 2010 SP1 Address Book Service:

Log on to the Exchange 2010 SP1 CAS server and open the registry and Navigate to the following:

HKEY_LOCAL_Machine\System\CurrentControlSet\Services\MSExchangeAB

Right-Click MSExchangeAB, Select New Key. Type the name as Parameters.

Select Parameters, and on the right-hand side, create a new String REG_SZ named  RpcTcpPort and put 55001 as Decimal Value.
