  1. SUM306: Troubleshooting tools: How to isolate and resolve issues in your XenApp and XenDesktop environment more rapidly Nicholas Connolly Tech Lead Application & Desktop Delivery Support Team - EMEA Tuesday, 16 Oct, 3:30 pm - 4:15 pm / CCIB - Room 113

  2. Agenda • XenApp connectivity issues • Citrix Policies • Session Sharing issues • XenDesktop registration issues • Citrix Scout and XD Collector • TAAS 2.0

  3. XenApp Connectivity Issues • Application launch failures: • ICA connectivity 1494/2598 • DNS resolution • Application launches stuck at splash screen

  4. “An error has occurred while connecting to the requested resource”

  5. Citrix Quick Launch 3.0 - App launch failures

  6. “Users report that their Citrix sessions have disconnected and they cannot reconnect”

  7. Citrix Quick Launch 3.0 - ICA Connectivity

  8. “An error occurred while making the requested connection”

  9. Citrix Quick Launch 3.0 DNS resolution

  10. “Users report that the application remains stuck at the splash screen for several minutes before successfully loading”

  11. Application launch stuck at the splash screen -Seamless Settings Configuration tool

  12. Citrix Policies

  13. Citrix Policies

  14. Citrix Policies - Policy Modeling and GP Results • Citrix Group Policy Modeling wizard • Simulate user or computers for testing • Run from App Center Console (Citrix AD and IMA policies) • Group Policy Results – current state of GPO’s • HKLM\SOFTWARE\Policies\Citrix

  15. “The session idle timeout does not apply at the given interval”

  16. Session Sharing • A user is consuming multiple sessions • Inefficient use of server resources • Published application settings can be different • Session Sharing disabled for specific applications • User Error (double clicking)

  17. Session Sharing • Separate Zone Data Collector (Zone Controller) • Try to narrow down the behaviour as best possible • Use CDF Control to capture trace on ZDC/Controller • Record key info: user name, client name, server and session id • HKLM\SOFTWARE\Citrix\Ica\Session\[n]\Connection • Analyse Trace for root cause

  18. Connection Details • HKLM\SOFTWARE\Citrix\Ica\Session\[n]\Connection • AppName(s) • App State • Color Depth • User Name • Domain Name • Encryption • Session Guid • Session Sharing Key

  19. “A customer reports that they are seeing multiple sessions for some users across the farm”

  20. Session Sharing and CDF Control

  21. “XenDesktop VDA’s showing as Unregistered on the DDC”

  22. XenDesktop Registration Problems XDPing • Information and status of Network Interfaces and Network settings. • Performs DNS lookup and reverse lookup on the IP address of the device. • Information on Time synchronization and time check for Kerberos Authentication • User information for login User • Machine information • Information on XenDesktop Services • Displays information on the Windows Firewalls • Queries the local event log to check for known events that are related to XenDesktop. • Provides client bandwidth and response time information from the VDA to the client.

  23. Citrix Scout • XenApp • XenDesktop • Captures key data points • CDF traces for multiple machines • secure and reliable upload of the data package to Citrix Technical Support.
