I would suggest you add another instance of Web Interface and license server to one of the other boxes. If there is a failure of your WI/LIC server just reconfigure the DNS to point to the new server for WI and change the farm license setting to the new box. With a small environment you don’t really need much more. If failover has to be automatic probably go with MS NLB or some form of MS clustering.

Hello, This is probably a stupid question but I just got assigned to support the Citrix farm in our environment so apologies in advance. We’re on Xenapp 5 with Presentation Server 4.5 – which I believe are the latest stable releases. We have Enterprise edition. We don’t have a load balancer. Right now I have 4 servers. I have 1 running as the license server and primary web interface. 2 are hosting applications using the built-in load balancing/failover in Citrix. I have the last box hosting special applications that I would like to keep separate. Is there a way to do some fail-over with the web interface without a load balancer? Looks like Citrix got rid of having the centralized web configuration recently. Also any general suggestions/pointers on how to achieve load balancing and failover without use of separate load balancer would also be greatly appreciated. Thank you.
