Hi,
Just stumbled on a citrix KB suggesting a way to drain users’ sessions from a XenApp Server,
The article is found here: http://support.citrix.com/article/CTX119661
And offers creating a load evaluator with “Citrix User Load” rule and set it to 1,
Why not use the following Load Evaluator technique?
Create a Load Evaluator with the “Scheduling” rule and remove all schedules from every day of the week, call the new Evaluator “Drain Mode” and apply it to start draining users from the server you applied the custom load evaluator to, I use it and so far it’s been working like a charm, just make sure the applications have all been published to other server on the farm as well,
Enjoy
