Citrix maintenance mode via PowerShell
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?
Allow users to change password via Receiver for Web
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)
