Scenario: A Citrix Architect designed an active/passive XenApp and XenDesktop environment for a customer, where the passive Site serves as the disaster recovery Site for all users.
The architect configured a DFS root for user profiles and redirected folders and configured DFS-R to replicate the user profiles and data to a fileserver in the disaster recovery Site.
During failover testing, no issues were reported; however, today the customer has an unexpected outage in StoreFront on the active Site which causes sessions to start flowing to the passive Site.
The customer reports that several users are experiencing issues logging on and has also stated that Citrix Director is NOT showing any issues for the passive Site.
What is likely causing this issue?
