For Citrix StoreFront and Delivery Controller communication, you need to specify XML service broker communication to travel over HTTPS or HTTP and specify a port such as 80 or 443. The XML service is used for application and desktop resource enumeration including handling user name and password data from StoreFront to DDCs.
This is a task you will have likely carried out, on a regular basis during your day to day Citrix farm administration. You have Citrix VDA machines that you need to put in maintenance mod. Maybe it’s one machine, maybe it’s a dozen. The reasons can be to carry out maintenance, or upgrades. Whatever the reason, yes you can do it via Studio, but what about PowerShell?
With the default installation of XenApp/Desktop 7.5+ by default, users cannot change their own passwords via Receiver for Web.
The StoreFront console provides an administrator with three options for managing passwords;
1. Never (enabled by default)
2. When expired (users will only be prompted when their password has expired)
3. At any time (users can freely change their password at any time)
