XenApp 6 How To: force the ICA listener on one NIC in multihomed installations

Sometimes, if you have your XenApp 6 servers in a multihomed environment, you may need to force the ICA listener to listen on only one NIC. For example it might happen that your web interface returns an ICA.launch which includes the wrong IP address.

The following steps shows how to perform the required configuration:

  • Then you have to set the binding order of your network card, putting the one you want to be associaated with the ICA listener at the bottom of the list, to do so:
      1. Open “Control Panel”
      2. Open “Network and Sharing Center”
      3. Click on “Manage Network Connection”
      4. Press “Alt” on your Keyboard
      5. Click on “Advanced” and then on “Advanced Settings”
      6. Put the connection you want to use at the bottom (XenApp 6 binds in descending order)
  • Open “ICA Listener Configuration”

  • Click on “Edit” –> “Network Adapter” and select the adapter you want
  • Click “OK” and close the console.
  • Restart the IMA service

  • Open a command prompt and run “qfarm”, you will see that your server is not listed along the others (here is explained why: )
  • Open the ICA listener console and put all NIC to listen again
  • Restart the IMA service again
  • Run “qfarm” again, now you’ll see that your server is listed twice and the first row contains the IP of the NIC you chose to use for the ICA listener
