STA Servers

You now need to specify the servers that are acting as the STA in your XenApp Farm. Here I only have one server so I have a single point of failure so I am going to add a failover server.

Add STA Server

Enter the FQDN of your STA Server and the port you will communicate on, for simplicity I am using HTTP here.

Citrix Web Management

I now choose to add my Failover Server with the correct URL for STA https://servername/scripts/ctxsta.dll

Test Connection

You can now shutdown your original STA Server and then try to access a XenApp Server in your farm. This should now fail to find your Primary Server and then find your Failover Server for STA. This will take a little longer than a normal connection due to the need to check the Primary Server first.
