Troubleshooting › Change the TCP Ports

Change the TCP Ports

If you receive a Communication Error from the Windows Client, it might be because another application on the network is using the same TCP ports as CA SRM (one such application is Laplink RemoteAssist™). If this happens, you will need to change CA SRM's TCP ports.

To change CA SRM's TCP ports

1. On the Application Server machine, shut down the Windows Client and the Application Server.
2. Locate five free TCP ports on your network. To view a list of the ports currently in use, run the following Windows command:

   netstat
   

3. Open the RPC_PORT.INI file and change the value of each parameter to one of the five new ports. By default, the RPC_PORT.INI file is located in the C:\CA SRM Data\Database\Configuration folder.

   The parameters that you need to change are listed below with their default values:

   GNS_PORT_NUMBER = 2571
   MRT_PORT_NUMBER = 2572
   LNC_PORT_NUMBER = 2573
   ASRPC_PORT_NUMBER = 2574
   RSC_PORT_NUMBER = 2575
   

4. Save and close RPC_PORT.INI.
5. Restart the Application Server and the Windows Client.

   CA SRM uses the new TCP ports and the conflict is resolved.
