Citrix Discussions Xenapp 7.9: Wait for local session manager: “I have a Xenapp 7.9 environment on Windows 2012 R2.When logging in through Citrix I got message “Wait for local session manager” for 20-30 seconds.You must take ownership and give admin users full control to be able to delete this value.This section is more important for shared VDAs like RDSH (Windows Server 2008 R2, Windows Server 2012 R2, and Windows Server 2016).Each value is detailed in the accompanying Word document.Customer Experience Improvement Program (CEIP) is enabled by default. Also see CEIP at Citrix Insight Services at Citrix Docs. The Connection Quality Indicator tells the user the quality of the connection.
Xen App/Xen Desktop 7.15 includes Adaptive Transport, which uses EDT protocol, which uses UDP Ports 1494/2598 for HDX connections to the VDA.
The UDP ports should already be open in the Windows Firewall.
Adaptive Transport is disabled by default, but can be enabled in the Citrix Policy setting HDX Adaptive Transport.
Citrix periodically releases Cumulative Updates for LTSR versions of VDA.
The latest Cumulative Update for 7.15 is CU1 (7.15.1000).
