Follow these steps to establish communication between two Windows® nodes. Note that in this example, the CP names are used as LU names.

For Windows® Node A, do as follows:
  1. Add the following entry to the local HOSTS file: 
    172.25.11.2  CP2.NETA.SNA.IBM.COM
  2. Create a configuration using the Personal Communications configuration tool:
    2. Click the SNA Node Configuration icon; or click Actions → Launch → SNA Node Configuration. The Personal Communications SNA Node Configuration window is displayed.
    3. In the Configuration Options list, choose Configure Node and click New.
    4. On the Define the Node window on the Basic tab, enter:

      Fully qualified CP name: NETA.CP1

      Click OK to complete node configuration.

    5. Choose Configure Devices. In the DLCs list, choose AnyNet® SNA/IP and click New.
    6. On the Define an AnyNet® SNA over TCP/IP Device window on the Basic tab, enter:

      SNA domain name suffix: SNA.IBM.COM

    7. Click the Routing Preferences tab:

      Default Routing Preference: Nonnative only

      Click OK to complete configuration of the AnyNet® device.

    8. From the Personal Communications SNA Node Configuration window, click File. Click Save as... and enter the desired file name to save.
For Windows® Node B, do as follows:
  1. Add the following entry to the local HOSTS file: 
    172.25.11.1  CP1.NETA.SNA.IBM.COM
  2. Create a configuration using the Personal Communications configuration tool:
    2. Click the SNA Node Configuration icon; or click Actions → Launch → SNA Node Configuration. The Personal Communications SNA Node Configuration window is displayed.
    3. In the Configuration Options list, choose Configure Node and click New.
    4. On the Define the Node window on the Basic tab, enter:

      Fully qualified CP name: NETA.CP2

      Click OK to complete node configuration.

    5. Choose Configure Devices. In the DLCs list, choose AnyNet® SNA/IP and click New.
    6. On the Define an AnyNet® SNA over TCP/IP Device window on the Basic tab, enter:

      SNA domain name suffix: SNA.IBM.COM

    7. Click the Routing Preferences tab:

      Default Routing Preference: Nonnative only

      Click OK to complete configuration of the AnyNet® device.

    8. From the Personal Communications SNA Node Configuration window, click File. Click Save as... and enter the desired file name to save.
  3. Start Personal Communications on each machine.
  4. Start your applications (for example APING).
