We as Citrites (Citrix employees) are encouraged to write KB articles for the Citrix knowledgebase (support.citrix.com). The following article I’ve written when I came across the issue and saw it wasn’t documented.
When stopping the Stream Service on a given Provisioning Server it can render some (but not all) target devices connected to that particular server unresponsive since the failover to other servers does not occur.
If you look at the stream process log (which can be found on the PVS server in C:ProgramdataCitrixProvisioning Serverlogs), you may find these entries: Continue reading “Stopping PVS Stream Service can Render Target Devices Unresponsive”
In a XenApp 6.5 provisioned environment the STA (Secure Ticket Authority) ID is not unique. This is because when a XenApp 6.5 (provisioned) is rebooted the NIC (Network Interface Card) has not completely started and loaded and is not functional when the Citrix services start. Therefor the STA ID is not changed with the MAC Address of the provisioned server (as expected).
Ever had the problem that your PVS streaming process becomes unresponsive when a time change occurs on the server or a hosted client? If you have HA enabled, a failover event will be triggered. But when all PVS servers see the time change occuring your targets will not be able to work. This is caused by the fact that PVS relies on the Kerberos method for authentication. Tthis makes a number of PVS services sensitive to time changes (just as your DC in Windows is sensitive for this). If there is a five minute (or more) difference between the Provisioning Server and your DC’s, Kerberos authentication will be broken, preventing PVS services from authenticating to the vDisk store and database.
