To brand our XenApp product a little bit at work, I created a favicon.ico file for web browsers. Nothing big, but it’s the little things, right? Unlike throwing the favicon.ico file in the root of your site, Citrix has a special place for the .ico files.
To change the current .ico file
Log into your Citrix Web Server and head here:
Find the file called IcaComboAll.ico. Rename this file to something else (don’t delete it in case you’d like to use it later) and change the name of the .ico you want to use to “IcaComboAll.ico” – case sensitive.
There may be other .ico files; you can change these as well.
Let me know how it goes.
